536455 V. Description of the invention (3) Subtraction, due to the occurrence of certain vibrations, there are many defects. ′ Friction flaws are generated on the surface. Therefore, _ — θ is taken out of the outside of the spray chamber from the opening of the spray chamber exit. Since the solid particles of 2-5 cannot be recycled for recycling, 帀: The solids outside the shooting chamber are reduced with time, and suitable supplementary solids are produced 2 = solid particles in the system. The recovery rate of solid particles is reduced, which is more important. This has also become the main reason for the increase in manufacturing costs. The rough surface is roughly ^ degrees from the metal plate. In addition, the granules from the exit of the spraying chamber are dropped on the metal plate again and are equipped with ::: bu: solid cylinder contact, or stick to such hen = & 泉Various rolled rolls on the surface produce wear marks on solid particles. In this case, the cleaning of the metal plate is caused in the surface of the metal plate surface. 7 θ Solid particles enter the metal. Another aspect can also be considered. The cleaning mechanism, etc., arranges the air near the outlet in the mouth to prevent the formation of solid particles; :: == Solid particle countermeasures. The opening of the opening to the exit is brought out, but 疋 'is given as appropriate; 丨, the average particle diameter is 3 0 0 _ ;;, the solid particles of the degree, flying around because of the use of a cleaning mechanism, the fine For particles, it is easy to cause the problem that the jet ejection will be interfered by the flow of the air jet particles, which will cause interference to the blasting. That is to say, with the solid particles on the obstructive side given the surface roughness of 25, the particle conflicts caused by the direct flying rolling / moon removal mechanism blowing from the upstream of the injection chamber are reduced, and the difference between the ejector and the metal plate is reduced. The velocity of the spray particles is lowered by the spray cow. In addition, not only $ 6 pages of C: \ 2D-CODE \ 9MO \ 91H7651.ptd V. Description of the invention (4) Direct reflection from the interior of the spray chamber is generated by the air clearing mechanism, which prevents the interference of =, but also, Shot, or dropped and deposited on the jet machine :: The case where the solid particles are sprayed on the surface of the plate is a kind of protective layer, the heart = the metal plate 'and the case of Jin Yu. In addition, the surface roughness of the metal plate is compounded by the flow of the particles sprayed by the jet machine, and the solid particles generated by the reflection of the net a, and interfering with the mobile phase particles of the dimer particles. Movement, therefore, it is extremely difficult to pre-seal it to the situation where solid solids are generated inside. In the case of setting a movable particle ejection device for spraying the solid particles, it is also difficult for the effective allocation: the suction of the solid particles to be attracted to the interior. -The suction device and the estimation of the capacity of the sprayed solid particles are so small that they are flying, so that they are sprayed; within ;; except that the mechanism is easy to blow the solid particles apart and flow is extremely difficult to guide; and to control these diffuse flying For the purpose of bead blasting of particles, de + + / For the case of the solid particles of the steel plate to remove the oxide layer ', will: blast) method, etc .: Larger spraying technology used, even if the applicable solid It is ideal to remove particles from the steel sheet. Even if it is applied to the surface roughness adjustment device, the effect is not 1 歹! ] Shikou, the so-called composition research and removal materials of Fu Zhou (Li Tekai Hei 4 ~ 256578, revealed that the solid particles ejected from the surface pr0Ject1 produced by milk and the like) are removed and left in the heart due to the blowing off of the hot body nozzle :: Moreover, the technique of using a scraper and loose particles on the steel plate is used.苐 Page 7 C: \ 2D-00DE \ 9M0 \ 9l] 17651 .ptd

However, because the device of the Japanese nasal 4+ is targeted, because the technical steel plate surface described in Hei 4_25 6 5 78 is ancient and private; and, for the purpose of removing the oxide layer, the size of the grain is generally required. : Make: two sudden forces (kinetic energy of solid particles), and solid particles will not cause solid particles to diffuse; = the surface of the metal plate only blows the solid particles with the gas, and is used in the present invention A solid surface accumulates and thus forms an indentation. The surface causes the surface to fall. In the case of the surface roughness, as described above, the air nozzles prevent the surface roughness from being sprayed to the outlet to solve the problem. As the solid particles are not sprayed, even if the solid particles are sprayed, there is no change in the roughness of the partially stacked solid particles. JiJi unveiled it here, solid solid, or 5 Therefore, if the steel covers the ground in the steel state, it will be uniformly shown in the adjustment particles, the particles will be scattered and cannot fit the surface of the plate on which the steel plates are stacked. Quality The object of the present invention is to provide a method for manufacturing a metal plate by using the equipment, which can produce a metal plate with an excellent cleanliness of the surface of the metal plate and a good appearance of the metal plate. In order to achieve the above object, the present invention provides a surface treatment apparatus for a metal plate as shown below. [1] A surface treatment equipment for metal plates, with ~ 0455 V. Description of the invention (6) Spraying device, the average particle diameter of the metal plate sprayed from the solid conveyed below 4 green 300 // m is provided with the spraying Device :: spray chamber; and cleaning mechanism, located on Xi + 'surface. ;. On the downstream side of the arm shooting chamber, the above-mentioned metal plates used to clean metal plates mainly include ordinary steel plates, t: rolled steel plates, and surface-treated steel plates. Cold-rolled steel sheets include high-carbon steels, electromagnetic steel sheets, nickel-all-indium hot-dip coatings, or dip-dip coatings, etc. In addition, the surface-treated steel sheet includes a steel sheet and a steel sheet with a steel sheet structure. Various surface shapes of S at the surface and vividness after painting:. The reason is that as the surface roughness of the steel plate that is pressed into the surface (micro-concave and convex shape of the surface) can be used to shoot the solid particles for implementation, it is required to be fine and uniform. According to this, the scope of spraying. So, although = = Oxygen: Layer • 'Not the main target of the plate of the present invention, but also other metal plates such as steel and titanium composite metal plates such as steel and surface-treated steel plates :: $ Aluminum alloy plate, titanium, and others. All kinds of metal plates can be made under the condition of & cold-rolled steel plates and surface treatments. Instead of batching the steel coils into the spraying chamber in batches, each batch is ==: It is necessary to impart surface roughness in the state of the steel sheet. It is necessary to spray flat body particles on the surface of the above metal plate transported by bismuth, which is used to solidify the surface of the metal plate. Utilize the bumps of the solid particles with small pitches. $ Shot on the surface of the metal plate, its kinetic energy will be transferred to page 9 C: \ 2D-CDDE \ 9M0 \ 91117651.ptd 536455 V. Description of the invention (7) Replace with press-in metal The force of the surface of the plate is used to generate an indentation (dent) on the surface of the metal plate. The small Λ of the marks is smaller than the diameter of the solid particles, so that fine recesses can be formed. That is, by spraying large f solid particles, a large number of minute indentations are formed on the surface of the metal plate, and the indentations can be more finely formed between each other. The micro unevenness with a very short interval. The surface is provided with a large number of concave portions formed in such a unit area, that is, a corrugated shape, which can improve the oil retention between the mold and the metal plate when used for pressure processing. When the average particle diameter of the solid particles exceeds 3 0 0 // m, it is impossible to form micro-concavities and convexities with a short pitch, and it is not expected to effectively improve the press moldability. At the same time, due to the surface of the metal plate, The long-term unevenness, that is, the undulation, deteriorates the appearance and appearance, and the vividness after coating is also deteriorated. From this viewpoint, when the surface roughness is given to a cold-rolled steel sheet or a surface-treated steel sheet, 'It is necessary to design the average particle diameter of the solid particles to be less than 3 0 // // m, preferably about 50 ~. As a solid particle spraying mechanism, it can be used The centrifugal rotary spraying device or air-type spraying device is described. However, in order to continuously process a wide and wide metal plate at high speed, a centrifugal rotary spraying device that can increase the spraying amount is relatively important. Here, the spraying of solid particles is The spraying chamber is performed. The spraying chamber collides the sprayed solid particles on the surface of the metal plate and partially separates the air-centered space from the space to prevent the sprayed particles from flying to the outside. The motor part of the rotary injection device is arranged in

536455 Five, clear instructions (8) ---- " a + inside the spray room can be. : To ‘as long as the part where the solid particles are ejected is provided in the lower part of the mouth chamber, and further,’ in order to recover the ejected solid particles, the ejection # is generally performed. Become a funnel with a larger angle of tilt than the angle of repose. The spray chamber is not to lift out to the outside: it must be a closed space, but it is necessary to prevent solid particles from flying continuously to the degree. It must be covered around it. Since there is an entrance portion of a metal plate to which Μψ8M and 1 贝 are aligned and an entrance portion of the second metal plate is ejected after the solid particles are projected, an opening portion is generated in this portion. The surface treatment equipment for metal plates carried at 5 W, 1 ν is composed of at least one dust removal chamber. —Dagger 4. ^ Door The structure placed in the spray chamber should preferably consist of at least one dust removal chamber. The dust collection chamber is equipped to remove the accumulation on the ϊ ΐ side and is separated from the spray chamber. Dust extraction room refers to the use of metal plates to transport solid particles from the metal plate and the space between them. A certain space of solid particles flowing out of the exit of the shooting chamber is used for the spraying palace. A dust-removing chamber is provided at the side of the dust-removing chamber and separated from the spraying chamber. Will interfere with the injection device i, forming a segment, the flow of solid particles still does not shoot, the flow of particles is not the same: in addition, because of the composition of the flow through the jet, and two; The flying solid particles can, to a certain extent, be subjected to complex motions caused by mutual interference. Depending on the situation, gas can be effectively carried out. The activity of shooting solid particles, on the other hand, uses the configuration of the sun and the other. Configure the dust removal chamber ’by cutting gas into the space C: \ 2D-OODE \ 91-10 \ 91117651.ptd on page 11 of the cleaning mechanism described above 536455

V. Description of the invention (9) Intentionally guide the solid particles to make them fly, and the property of falling onto the metal plate can reduce the removal. These particles are always sent to the outdoor without the particles on the metal plate ^ to In the case where a gas injection device is installed in the solid injection room at the exit portion of the nozzle, on the other hand, during the flight, solid particles will diffuse to the injection device and the solid surface diffusion of the solid particles is effectively given. Therefore, ^ ^ Belongs to the board, hinders Mu. This type of removal method cannot be adopted. That is, a dust removal chamber is disposed on the surface of the jujube recording surface, and the solid particles can be effectively removed by moving the solid particles in a spray and moving the particles to another space. In addition, in the case where the solid ejection chamber caused by gas ejection in the ejection chamber and the dust removal chamber faces the ejector on the surface of the metal plate, the ejection chamber volume may be set to hang rubber and It is designed so that the pressure in the dust removal chamber is not higher than that of the solid particles in the spray. It will not flow back into the spray equipment. Field + shot h and separated from the shot chamber area t will not hinder the deer facing the metal plate surface. The functional separation of the solid particles accumulated on the metal plate to remove, the partition refers to the separation of the particles by the action of the particles in the dust removal chamber, which will not hinder the flow of the solid particles sprayed. The sectional area of the connection part with the entrance of the outlet of the dedusting chamber should be narrow, or it should be sprayed. In addition, the pressure in these shooting chambers can also be reduced to make the dust removal chamber shooting chamber. [3] The surface treatment equipment for metal plates according to [2], wherein the at least one dust-removing chamber is composed of a plurality of dust-removing chambers arranged continuously, and each of the dust-removing chambers has a structure separated from each other. Preferably, the at least one dust-removing chamber is constituted by a plurality of dust-removing chambers which are continuously arranged.

536455 V. Description of the Invention (’) Each of the dust extraction chambers has a structure separated from each other by plaques. A structure that separates the connection part between the dust removal chamber, the room king, and the king of the valley and the deer from the dust removal chamber arranged on the delivery side of the mouth is separated. As a structure for partitioning the dust-removing chamber, the same structure as the above-mentioned mechanism for partitioning the spray chamber and the dust-removing chamber can be adopted. By arranging a large number of dust extraction chambers and separating them, the residual amount of solid particles in the dust extraction chamber on the downstream side of the machine can be reduced, and the concentration of solid particles flying in the downstream dust extraction chamber can be reduced by 4 μM. . With this, the opening of the dust outlet of the dust extraction chamber can be taken out of the solid particles outside the system. "Xi [4] The surface treatment equipment for metal plates as described in [2] or [3], to the small dust removal chamber has a suction device to attract solid particles. Xi 1 In the dust removal chamber, the solid particles are blown by gas jets. Diffuse ?, it is not easy to fall on the metal plate again. Especially the use of the increase of :: Divide the grain product, because the solid particles carry on the diffused flight for a long time, therefore, the particles fall on the metal plate and are taken out of the dust outlet. The situation becomes almost extinct. However, to increase the volume of the dust removal chamber is also limited by the equipment installation space. Therefore, the above method also has unachievable surface. Here, use the equipment to attract solids flying in the dust removal chamber. The suction device such as a blower (blower) for particles can reduce the solid particles falling on the metal plate even if the volume of the dust removal chamber is relatively reduced, and reduce the amount of solid particles that are taken out of the outdoor. ^ [5] [2] to [4] The metal plate surface treatment equipment, at least one dust removal chamber has an upper height of 500 mm or more at a position closest to the metal plate. There is The volume of the solid particles diffuse fly low annihilation

536455 V. Description of the invention (11) The amount dropped directly on the metal plate and taken out of the system. However, because of the shape of the dust removal chamber, the scattered solid particles may be dropped on the metal plate due to its shape. For example, in the case where the upper part of the dust removal chamber must be partially lowered, when the solid particles pass through a short distance from the metal plate, they may easily collide with the inner wall of the dust removal chamber, and may fall on the public board. However, the solid particles to be dropped will fly again with the flow of air by using the high ceiling of the dust removal chamber. ^ Therefore, in this surface treatment equipment, as the height of the upper part of the dust removal chamber, that is, in the case of a metal plate, these distances are also at least 500 mm or more. If the height is less than 50 mm, it will be difficult for the solid particles scattered by the gas jet to continue to diffuse, which will cause the metal particles to fall easily. Specifically, if the injection volume in the injection chamber is about 100 kg / min, the distance between the upper part of the room except the "1" and the metal plate is the most distant from the distance of 500 mm. However, if the amount of solid particles ejected from the spray chamber is large, it is necessary to increase the height of the dust removal chamber. This is to allow the particles of Gengxi to diffuse for a long time in the dedusting room. Evening, * body [6] The surface of the metal plate as described in any one of [2] to [5], at least one of the dust-removing chambers has an exit portion that narrows the upper part of the dust-removing chamber and the structure of the space. _As mentioned above, the height of the dedusting room has an effect of increasing the spread of Gona ’s as the height increases. It is best to set the distance between the upper part of the dedusting room and the closest position where the metal particles are easy to lead to more than 50 mm . However, the distance between this chamber and the outlet of the dust-removing chamber is to narrow the upper part of the dust-removing chamber, the metal plate, and the structure. The height of only this part may be less than 500 mm, and the space of e is preferred. $ Its lower.

V. Explanation of the invention (12) The belt part is provided with an opening for carrying out the metal plate, and the solid part of the part comes from: the opening. The movement from the opening to the outside causes the metal plate to flow out. ; = Multiple doors? By increasing the volume of the dust removal chamber, it can largely be taken out of the solid particles on the board. As the dust particles directly flow out from the opening of the dust removal chamber during the diffuse flight, this can also cause the deterioration of the recovery rate of the body particles. . … Consolidated here. 'This surface treatment equipment is only near the outlet of the dust removal chamber, and the space between the upper part of the dust removal chamber and the metal plate is narrowed, so that solid particles and dust removal that flow to the outlet of the same dual-use dual-use can be used. The inner walls of the chamber collided, and it was dropped onto the metal plate as shown. Whereas, [7] the surface treatment equipment for a metal plate as described in [6], at least i of the chambers have an upper structure which is inclined downwardly in the direction of the exit of the dust removal chamber. Dust removal As the upper part of at least one dust removal chamber faces the exit of the dust removal chamber. It is inclined downward. Therefore, in the surface treatment equipment of the above [6], there is no step difference in the two-way part of the dust removal chamber, which can effectively make the solid particles flowing to the dust removal chamber and the upper part conflict with the inner wall of the dust removal chamber while flying. And intentionally _ 2 out D fell on a metal plate. Indy makes it, in the surface treatment equipment of [5], the "dust removal & upper part" mentioned in [5] above does not contain the "slope downward towards the dust removal chamber of the dust removal chamber" of the surface treatment equipment. part. In other words, the direction between this part and the metal plate may be 500 mm or less. ,distance

The situation that the solid particles ran out of the dust removal room was reduced; As a result, in the surface treatment equipment of [6] and [7], because the solid particles directly flow out of the above-mentioned openings are deliberately caused by human beings = the dust chamber is blown out, and the falling solid particles are blown toward Inside, the number of metal plates under the T will not be taken out from the opening of the dust removal chamber.

However, "in the case where a very small amount of solid particles remain on the metal plate", if these solid particles are not removed, the shell may cause problems in terms of cleanliness and performance of the metal plate. Here, in the surface treatment equipment of [9], in order to completely remove the solid particles remaining on the surface of the metal plate, a gas injection device and a suction device provided opposite the gas injection device are arranged on the sending side of the dust removal chamber.

Borrow, drop the transport roller parts produced from the metal, there will be solid washing, solid pressure cleaning, and pressure water purification. The time-based washing can only supplement the gold side that is carried out. However, the metal of the strong device at the surface of the solid particles that is sprayed out of the washed solid particles is reversed, and the particles are sprayed on the surface of the metal plate. The compressed air is not sprayed, but it is left on the metal plate, or it is flying on the peripheral plate, which causes scars. That is to say, cleaning and removing can not only clean the flying around the gold. Wash with water The degree of flow of the metal plate is not a problem. However, to improve the removal efficiency of the solid particles, the pressure water below 2 is enough to improve the cleaning effect. 5.

After drying, but there is still a very small amount of solid particles remaining in the metal. It ’s a small part of the metal plate that generates a small turtle. The small cracked part captures a small amount of the two with the cleaning solution at the same time. In this case, due to the work of the surface tension of the liquid, there is no ::: body particles 'but'-'Once the metal plate has been dried and used; two-liquid residue', solid particles can be easily removed. … The rabbit washing forced drying device only needs to have the ability to evaporate the washing liquid remaining due to washing. 'It can also be dried by warm air or electric 敎 = according to this' and can also be described in the forced drying installation at the same time. Gas wiping. ^ W ^ [1 5] The surface treatment equipment for a metal plate as described in [1 4], which has a gas wiping device for the metal plate arranged on the downstream side of the forced drying device. In order to remove the solid particles after drying, it is enough to spray compressed air. After this operation, only a very small amount of solid particles remains, and the aforementioned problem of scattering of solid particles does not occur. Therefore, an air nozzle may be provided as a gas wiper opening. Furthermore, it is not necessary to spray the compressed gas on the metal plate in its entirety, and it is sufficient to arrange air nozzles around the plate end portion of the metal plate from the center of the plate toward the plate end. The surface treatment equipment for a metal plate as described above is disposed in a production line of a metal plate and is used in the production of a metal plate with excellent surface characteristics. For example, at least one of the upstream side and the downstream side of the lambda-rolling mill disposed at the rear stage of the hot-dip steel sheet production line and the rear stage of the continuous annealing production line is used to produce hot-dip galvanized steel sheet and cold-rolled steel sheet with excellent surface characteristics . In this way, it is best to combine the surface treatment equipment with the quenching and rolling mill.

Description of the invention (19), however, it is also possible to arrange the quenching and rolling mill only in the hot-dip steel plate manufacturing line and continuous annealing manufacturing line, and to set the surface treatment equipment of the metal plate to other lines. Surface treatment is performed by batch processing. The hot-dip ore steel sheet shown here is a hot-dip galvanized steel sheet, an alloyed hot-dip galvanized steel sheet, a hot-dip aluminized zinc steel sheet, a hot-dip galvanized aluminum alloy steel sheet, and the like. In addition, the surface characteristics refer to surface characteristics related to the quality of a metal plate, such as press-formability, margin after coating, and the like. The present invention provides a method for manufacturing a metal plate as shown below. [16] A method for manufacturing a metal plate, which has the following steps: a step of spraying solid particles having an average particle size or less than 'm' on the surface of the metal plate continuously conveyed ; And t υ υ μ a step of removing particles adhering to the surface of the metal plate sprayed with solid particles.

The step of forcibly drying the surface of the metal plate before the particles are on the metal plate. [2 0] As described in [1 9] δ, the method for manufacturing a metal plate has a step of washing the metal plate before forcibly drying the surface of the metal plate. The present invention also provides a surface treatment apparatus for a metal plate as described below. [+21] —A kind of surface treatment equipment for metal plates, which has the following characteristics: direct control of solid particles below 3 0 0 # m on the surface of the metal plates that are continuously conveyed; and a device for removing deposits In the surface treatment equipment, which is deposited on the surface of the metal plate, the solid particles emitted by the bead blasting method have smaller shot particles that collide with the shape of the metal plate to reflect or diffuse. Flying in the air, 'If the solid particles fall into the spray device to spray the solid particles, although the solid particles are still on the board, it is very difficult to control the flow of air in the spray chamber particles. The particles are accumulated on the entry side of the spray device. It is particularly difficult to deploy multiple injection devices. The entry side of the spray chamber is used to remove particles that are more conventionally used to remove the oxide layer. Therefore, after spraying from the spray device into a mark, it flies to the surroundings and falls on the metal plate again. If the delivery side is set, even if the flow of gold particles and the flying particles that are continuously conveyed do not accumulate, the solid particle knife cannot be completely prevented, especially when the same ejection is performed. It is necessary to control the solid particle accumulation. The consideration given to the solid particle size of the surface treatment equipment particles falling on the metal plate of the spraying device is based on the entry side, which is limited to the entry side and does not hinder the proposed invention. Even if there are flying solid particles, remove the rough surface of the shooting device before performing the mouth shot.

Description of the invention (magic), the body particles are provided with roughness on the front surface of the metal plate, and the solid particles accumulated in the area are removed in advance. The particle removal device is best. Based on this, the solid particles are located. The distance between the deposit removal device and the ejection device placed near the entrance side of the spray device in the sister's sin is large. This is because even if the metal plate = right, the deposit removal device is falsely sprayed with J-set "—50 mm or less, even if the distance between the carved particles α: and He-she is only ^ Μ $ -Γ ns,. Alpha limb particles fall down on the metal plate, and the helmets are almost piled up to prevent the roughness of the spray by the spray. The larger the amount of accumulation, the more the amount of accumulation is also a secret. § In addition to solid particles, the higher the linear velocity; It is necessary to shorten its distance. Therefore, it is also necessary to shorten its distance. The sufficient time and degree of solid particles to be stacked must be in the entire wide direction of the metal plate. As long as it can be removed, it can give a wide surface roughness. Even accumulation of ΐ = particles is sufficient, and it is best to do so. If it will increase the probability of removing all solid particles flying in the air, spoon mouth ancestor particles I will have adverse effects [22 ] As described in [21], the metal object removal device is a gas F 啧 surface treatment equipment. The above-mentioned accumulation selection is selected as a combination of the Chuangu㈣ device and the suction device as a deposit removal device.

The shooting device or suction device such as this 2 plate is used as a deposit, except that the gas spray removal device does not belong to the entire transportation and therefore 'accumulation' 7 The contact of Monsoon plate can prevent the above-mentioned disadvantages [23] such as the surface treatment of the metal plate described in [21] or [22], and the accumulation on the surface of the metal plate on the entrance side of the above device. Here, the measurement of the “accumulation measurement device” refers to the measurement accumulation == refers to the amount of f or more. In the surface treatment equipment, a deposition measurement device for the surface of the metal plate is provided on the entrance side of the shooting device. The measuring mechanism determines whether there is a deposit of 4 on the metal plate or the accumulation of solid particles, and the output of the particle removal device can be adjusted based on the result. Specifically, the pressure and flow of the gas injection device are increased in the presence of solids. Or increase suction + U toe and bow force According to the amount of solid particles deposited, adjust the pressure and flow rate of the gas, or the attractive force of the suction device. The solid particle removal device is operated under the ideal conditions. [24] Surface treatment of metal plates as described in [23] The device is a deposit measuring device for measuring the reflected light on the surface of a metal plate and measuring the amount of deposits from the measurement and processing. The galvanized steel sheet and the cold subject of the present invention are Rolled steel plates, etc. have metallic light.

When particles are deposited on the steel plate, the reflection intensity of light drops sharply. By measuring the reflected light, the presence or absence of metal plate deposits can be measured or the amount can be measured with high accuracy. As the reflection device, a conventional light sensor can be appropriately selected and used. Moreover, this invention provides the manufacturing method of a metal plate as follows. [2 5] A method for manufacturing a metal plate, which has the following steps: a step of cleaning the surface of the metal plate; and a step of spraying solid particles on the cleaned metal plate.

In the case where the surface roughness of the metal plate is adhered to the surface roughness such as abrasion components, the metal surface roughness or the like is used. According to this, dry burning can be done in advance, so the method of injecting water onto the metal plate cannot be effectively given to the metal plate. As a cleaning device, a wide range of 10 kgf / cm2 or less is sufficient. However, the spraying pressure is generally on a foreign material on the surface of the plate, and the spraying pressure is higher.

The metal plate 1 is provided with a rough product, and the metal plate 1 is conveyed by a centrifugal rotary spraying device by: moving the surface of the plate. Centrifugal rotary spraying device The blades 10 driven by the dream particle 11 of the solid particles 14 are accelerated by centrifugal force to pass through the particles for solidification. The pellets 14 are supplied to the blades 10 from a state door ++ B stored in a box or the like. An openness adjustment net Z 'is set in the middle of the way. The supply of solid particles 4 can be controlled by adjusting the openness. Fig. 1 shows a state in which solid particles are sprayed only on the upper surface of the metal plate 1. However, the same device may be provided on the lower surface of the metal plate 1, or it may be sprayed on both surfaces of the metal plate. In addition, a plurality of spray devices may be arranged in the width direction and the length direction of the metal plate. The solid particle ejection unit is arranged in the ejection chamber 2 so that the ejected solid particles 14 do not fly to the outside. in

Description of the invention (27) The solid particles 14 sprayed from the inside of the spraying chamber 2 collide with the surface, leaving a corrugated indentation and being reflected to the surrounding The fly number falls to the lower part of the spray chamber 2 by the action of gravity. In particular, most of the wind current generated by the rotation of = 10 is from the gold row: 20: the lower part of the spray chamber. The falling solid particles 14 are mistakenly recovered by the particle recovery clothes 20, and are repeatedly cycled in, = shot inside the shot ::-part of the body particle 14 spray: diffused around after reflection, and dropped again on the metal plate =: The shooting chamber is taken out 'or on a metal plate! The high-speed transfer of gold is followed by the flow from the injection chamber. There are openings at the entrance and exit of the spray chamber 2 so that the metal plate 1 and the structure of the spray chamber 2 are directly connected. "The design is not extensive. The outlet of the spray chamber 2 is provided with rubber = = Yu metal ^ separated. The rubber plate 4 used between the quiet room and the m m is in a state of contact, but if it is slightly pressed, it will not be in the full category, and the λ metal plate is not connected. Therefore, if: This level of situation can also be related to: 凊 Quiet chamber 3 a with gas injection device 5 inside It has a fixed 53 body to accumulate metal in the mouth ~ ^ ~ gas injection device However, it is necessary to ensure sufficient blowing: = Below, the degree of air volume, pressure, and the number of nozzles. For example, using ^ ^ f 14 Cheng Cheng's stainless steel particles as solid particles 14 using an average of 2 diameter 85 as the gas nozzle; brother, if air pressure is used 咼The ability to press the milk nozzle about 3m3 / min is enough.

Description of the invention (28) In addition, according to the amount of solid particles sprayed in the spraying chamber 2] and the line speed ^ 'The degree of solid particles 1 4 on the blowable metal plate} is determined along the The number of nozzles arranged in the forward direction of the metal plate 1. In addition, it is preferable that the width direction arrangement is determined according to the plate width direction of the metal plate 1. That is, it is arranged so that the gas flows of the respective nozzles do not interfere with each other. On the other hand, in the case of using wind gas in a gas injection device, it is necessary to use a micro-slit nozzle for the conditions of board finding 1000 mm, linear speed 50 mpm, and particle spraying volume 60 kg / min in the spray chamber. The air volume is set to 40 m3 / min or more. In addition, in Fig. 1, the distance between the upper part of the dust removal chamber 3a and the metal plate is at least 500 mm or more. The volume of the dust-cleaning chamber requires a space where solid particles can be blown for a long time by the gas injection device "~ 5d. Therefore, the larger the better, according to this, from the viewpoint of this, the upper part of the dust-cleaning chamber 3a and the metal plate! The separation distance is as described above. ^ 'Figure 1' as the structure of the dust removal chamber 3 & the slope is downward facing the exit direction, and at the same time, the gas nozzles 6a, 6b are arranged at the exit of the dust removal chamber. The gas ejection device "~ 5 (1) blows the solid particles ^ hunting the inclination of the upper part of the dust removal chamber 3a, so that the reflection in the dust removal chamber 3a is directed toward the fly; 〇 side flying person falls on the metal plate, and the gas ejection device 6a will fall = solid particles are blown to the upstream side of the dust removal chamber 3a. In addition, the gas injection device 6b is provided to prevent the forward flow of air generated by the movement of the eight plates 1 from the dust removal. The stomach outlet% of the chamber 3a is the one that brings the solid particles 14 out of the system (outside the system composed of the dust removal chamber 3a and the equipment for recycling the solid sculpture 100 particles for recycling), and the gas nozzle service # 、 置 6a 、 6b may be the same degree as the gas injection devices 5a to 5d. less

536455 V. Description of the invention (29) Air volume. This is because most of the solid particles 4 have been scattered in the dust removal chamber 3a. In addition, a rubber curtain 9 is installed at the outlet of the dust removal chamber 3a to prevent the solid particles 14 from flowing out from the opening. The rubber curtain 9 is preferably installed so as not to contact the metal plate i. The contact with the metal plate 1 may cause scratches directly or be embedded in the solid particles 14 to cause surface defects. ^ On the other hand, the solid particles 1 4 that are scattered in the dust removal to 3 a by the gas injection device 5a to 5d or 6b fall to the lower part of the dust removal chamber 3a, and are recovered by the particle recovery device 20 and are circulated. The conditions of use are normal, but 'if the continuous transfer of the metal plate 1 increases the concentration of the flying solid particles 14 in the dust removal chamber 3 a, the solid particles 4 will easily fall on the metal plate due to the interference of the solid particles 4 Therefore, in order to prevent this, a particle suction device 7a is provided separately from the particle recovery device 20, and a solid suction device 14 that sucks flying solid particles 14 from above is also provided. The particle suction device 7a is connected to the dust collecting body, and attracts the solid particles in the flying dust. 4 The solid particles flying in the dust removing room are in the dust removing room. Most of the solid particles that are not particularly easy to fall on the metal plate 1 < blow off, can be recovered by the particle recovery device 20 with a solid force that is sucked into the dust removal chamber 3a. Machine 15 by the suction of the blower. However, it is not necessary to have the ability to attract the grain. This is because the concentration of solid particles 14 in the dust-removing chamber 3a has not reached a certain level, and it is because the metal plates 1 all fall below the dust-removing chamber 3a. According to this, in fact, as long as the amount of energy

536455 V. Description of the invention (30) '--- Also, the more the weight of the solid particles 14 sprayed in the spray chamber 2 is, the more the amount of particles brought into the dust removal chamber 3a is, so the particles can be changed according to the increase of the concentration The suction air volume of the suction device 7a. # In addition, a classification device such as a cyclone dust collector is arranged between the particle suction device 7a and the dust collector 丨 5 to constitute a similar circulation system such as returning solid particles of a certain size or more to the particle recovery device 20, and the like can be reused by the particle suction device. 7a attracted solid particles. According to this, even if the suction amount of the particle suction device 7a is set to a large value, a large amount of solid particles are drawn from the dust removal chamber 3a and returned to the circulation system by the classification device, so the amount of solid particles captured by the dust collector will not be increased. There will be no reduction in the amount of solid particles in the cycle. However, it is not necessary to arrange a gas spraying device inside the spraying chamber 2. However, in order to reduce the amount of solid particles carried out of the dusting chamber 3a from the spraying chamber 2, a lice spraying device may be provided. However, it is necessary to blow and fly the solid particles j 4 without blowing the air volume and pressure of 4 degrees from the spray device 10 toward the solid particles i to the metal plate i. Fig. 2 is a view showing an embodiment 1-2, and a diagram showing an embodiment in which the dust-removing chamber is arranged in the spray chamber 2 in a continuous two-base arrangement. The dust collecting room 3a has his dust collecting room 3b, which is separated by a rubber curtain. The structure of spraying 1 m of dust to 3 a is the same as that shown in FIG. 1 ′, so the description is omitted. The interior of the dust removal chamber 3b is provided with gas injection devices 5e and 5f for removing solid particles 14 from the metal plate. The upper part of the dust removal chamber 3b is provided with a suction device. In addition, gas outlets 6c and 6d are arranged at the outlet of the dust removal chamber 3b so as to prevent the solid particles 14 from being taken out of the room.

V. Description of the Invention (31) However, since the majority of the solid particles 14 from the spray chamber 2 are removed from the dust collection chamber 3a on the upstream side, the amount of solid particles 14 that are brought into the dust collection chamber on the downstream side is relatively reduced. 'The volume of the dust-removal chamber 3b does not need to be increased as much as the dust-removal chamber 3a upstream. It is not necessary to dispose the particle suction device 7b, and it is sufficient if the blowing ability of the gas jet is lower than that of the upstream side. ^, Fig. 3 is Embodiment 3, and is it shown that the dust removal chamber 3a is arranged in the spray chamber for display? This is a diagram showing an embodiment in which a brush-type particle removing device 27 is disposed on the downstream side of the dust removal chamber 同时 at the sending side. Fig. 4 is a detailed view showing a brush-type particle removing device 27. The brush-type particle removing device 27 shown in FIG. 4 is composed of a brush roller, a suction tube 迢 23, a dust collector 24, and a support roller 25. The brush roller is a shaft roller 22 that is covered with brush bristles 21, and includes a mechanism that presses the brush bristles against the surface of the metal θ plate and rotates them at the same time. The suction duct 2 3 has a structure for covering the entire brush roller to prevent the solid particles 14 flying from the brush roller from flying to the surroundings. In addition, the dust collector 24 is a gas generator for generating a suction air for recovering the solid particles 14 flying in the suction duct. The supporting rollers 25 are rollers for receiving the abutment load so that the brush roller is pressed against the metal plate 1 to protect the metal plate from being bent. Here, as the brush roller, a diameter of 200 to 50 mm can be used, and it is preferable to adjust the number of rotations of the brush roller and a pressing load against the metal plate. The material of the brush bristles is required to be a hardness that does not cause blemishes even when pressed against the surface of the metal plate. Engineering plastics and polypropylene-based wires can be used. In addition, the diameter of the electric bristles is less than 1 min, and is preferably 1 to 1 mm.

536455 —— " Ⅴ. 5. The degree of invention (32). This is because of the production of electric bristles, which is the second reason: it is easy to pull on the surface of the metal plate. In addition, there are brush rollers that use = as a means to remove fine solid particles, which can be generated on the metal surface. Second, the effect of grinding is included for the purpose of knowing the effect. It is necessary to have X defects and is not suitable for the present invention.体 粒 1 4 向 围 # | It is used to prevent the brush from rolling π π ρ Α ρη J η The country's flying coating M / the same as the solid structure of the brush roller If the size of the brush roller is the same as the structure of the brush . However, radon attracts air volume, so as long as the volume of the official channel is too large, it must be increased. In addition, in order to ensure a large-circle shape of the T brush roller, the brush roller and the suction pipe can attract solid particles at a wind speed of about 14 degrees, and the electric value is necessary. , Clearance, there is a dust collection device 24 set below a certain value, which is an airflow of sucking milk with a suction fan and the like in shape, and the solid particles 14 in the suction pipe 23 and the lead box 23 are used to attract the Soaring on the suction device 23 for catching, such as a suction device 23 and a dust collector. However, the classification device and the classified solid may be provided with a solid returning to the particle recovery device 20 such as a cyclone dust collector = the device 20. Shooting can eliminate the recovery rate of solid particles; to reduce the spraying of metal plates, the roller 25 is selected to drive the motor synchronously to withstand the linear speed of the brush metal plate. The yttrium bismuth shows that the brush has been rolled on one side of the metal plate, but the brush rollers are arranged on both sides of the metal plate. In this case, the roller of the branch building is not needed. Figure 5 shows the high-pressure gas-type particle removal device used in Embodiment 1.

The high-pressure gas type removing device is composed of a high-pressure gas ejection gas directed at a metal plate surface, and a suction bow 丨 f disposed opposite to it. The suction device is composed of a suction channel 32 and a dust collecting device 34 for suctioning the solid particles 14 flying in the suction channel. The eight-gas injection device 31 is a nozzle for injecting high-pressure gas, and is a micro-slit nozzle for processing a wide plate. This is because the solid particles remaining on the metal plate 1 can be blown off without any leakage. The direction in which the high-pressure gas is sprayed is preferably relative to the forward direction of the metal plate, and the direction of the spray is to be inclined with respect to the surface of the metal plate 1. This is because even if the spray is performed perpendicular to the surface of the metal plate, the solid particles do not fly in the direction of the suction pipe 32. In addition, high-pressure gas discharge = wind speed is determined by the size, specific gravity, linear velocity, and the like of the solid particles 14. However, it is necessary to ensure that the solid particles 14 fly sufficiently above the wind speed of the metal plate 1. A wind speed of 30 m / s or more is appropriate. The suction duct 32 has an opening portion which can cover a range where the solid particles 14 are flying by the gas injection device 3m. At this time, the body particles "do not fly to the position 2 which attracts more to the pipe, and the guide portion 33 is fixed. The guide 5 / section 33 is made of rubber or: take a good contact with the metal plate]. If " the plate makes the surface of the metal plate], there will be cancer on the surface of the metal plate.

The steel plate that gives the surface roughness = shank = table φi. As a result, the steel plate 'its coating surface mold is mainly a substrate with a plate thickness of 0.8mm, which is cold-rolled and hot-dip plated. For hot-dip galvanized steel, the sprayed solid particles are average;体 粒。 Body particles. This is a particle made of a solid sphere made of SUS304 by "1" by the gas atomization method 仫 5. In order to make use of the large spheroids (1Γat〇miZing), A 彳 is * M 1 ", The leather, paper-like micro concavo-convex is on the surface of the steel plate, and exhibits excellent pressure forming characteristics. The office is used for centrifugal spraying of solid particles. The second maximum rotation speed is 50 mpm, and the adjustment of Gu Lin Ge private = Rike, 6 and the steel plate is set to leg g / min. The mouth limb particle supply device 12 sets the injection volume: dust: 3 a system, volume 2m3, the distance between the upper part of the dust collection room and the steel plate ^^ The opening at the exit of He 2 is an opening with a height of 14 mm.

To this end, stick the tape to the steel plate and measure the number of particles adhered to the tape. Number of unit area. ^

536455 V. Description of the invention (40) On the other hand, as a comparative example of the present invention, the case of the device configuration shown in Fig. 8 equipped with the same mouth shot chamber as in this embodiment was also investigated. This is a case where the high-pressure gas nozzles 30a and 3 Ob are arranged inside the spray chamber, and the person does not have a dust removal chamber. In this case, the number of solid particles remaining on the steel plate carried out from the spray chamber was also determined in the same manner. As a result, it was found that the residual amount of the solid particles in this example was 5 to 20 particles / m2, while in the case of the comparative example, the residual solid particles were 2,000 particles / m2. Most of these residual solid particles are flying around the manufacturing line and falling on the steel sheet, and some of them are inserted between various rollers and steel sheets arranged on the manufacturing line, and cause surface defects. In addition, it is possible to fully anticipate the case of flying in the air at the same ratio as the amount of solid particles deposited on the steel sheet. As the long-term operation continues, the recovery rate of the solid plate is also in the apparatus according to this embodiment. There is a very large difference between the configuration and the configuration of the comparative example.

The upper and side portions of the spray chamber 106 are provided with suction ports n 0a, 1 0b, which suck solid particles flying in the spray chamber. In addition, the lower part of the spray chamber is jealous of the inclination of the particles greater than the angle of repose, so that the sprayed solid particles are collected at the lower part of the spray chamber and recovered by a screw conveyor 1 1 1. The solid particles recovered by the screw ', the conveyor 111, and the suction ports JJ 0a, 丨 i 〇b ^ ^: The solid particles are guided by the centrifugal force classifier 1 1 2 and are removed by the micro dollar and mixed foreign matter. The dust collector 11 3 performs processing. In addition, the designated particle size obtained by classification can be returned to the storage tank. The structure of the ring ^ f can be continuously adjusted, thereby continuously adjusting the surface roughness of the metal plate 〇i. Figure 13 shows the spray in detail. This plan view is shown by a side view 14 of the equipment inside the chamber 106. The centrifugal rotator that sprays on the metal plate + the entrance side of the injection devices 109a to 109c, for the purpose of blowing and depositing on the gold $ = grains, inside the injection chamber 106 is installed a rolling body connected to the compressor pipe Device 11 5a ~ 115c. Each gas injection device 115 & is composed of a plurality of flat nozzles with the discharge direction as the width direction of the plate. The 5c system = ί electromagnetic sprayer 116 provided by the body spray device can change the injection Λ. Here, the gas injection device 115a The setting of ~ 115c = the spraying position of the rotary spraying devices 109a to 109c will be sprayed from the rolling body as it is separated, even if solid particles are removed from the metal plate.疋 In order to impart 胄 to the surface roughness of the spraying device, the purpose of preventing particles from being deposited on the metal plate again can be prevented as much as possible. In addition, the solids of 氚 钿 1 1 5a ~ 11 5c are solids removed, such as km x milk ejection device 536455

The unique spraying device gives the range of solid particles immediately, and does not accumulate in gold. However, if there is a reason, it is better to download. The surface roughness of the board is sufficient. In addition, the lower part belongs to the plate. Therefore, the particles deposited in the lateral range where the static electricity and other sticky particles enter the surface injection device fall by gravity. There is no concern that a gas injection device is installed under the metal plate. A gas injection attack is set. The upper part and the side part of the spray to 106 are provided with suction ports 110a and 110b which are connected with the suction blower ^, and the suction is reversed in the spraying chamber; dusty solid particles ... Changing the opening degree of the regulating valve 11 17 can change the exhaust flow rate. In addition, a centrifugal rotary spray device 109a to 109c has a light receiving sensor at the entrance side of the detector which detects the intensity of the light source and the reflected light. 丨 ": 11 8c The output of the two light receiving sensors is used in The intensity of the reflected light in the state where the particles are deposited on the metal plate is normalized. When the intensity of the reflected light is reduced, the solenoid valve 1 and the opening and closing of the solenoid valve and the opening degree of the control valve 11 are controlled by the control calculation device 1 丨 9. In order to increase the flow rate of the gas injection device 丨 5a to 丨 丨 "and the flow rate of exhaust gas from the suction ports 11 〇a, 11 〇b. After the air has been purged, it is desirable to install a deposit measuring device in order to fully confirm whether the surface of the metal plate is normal. As described above, the surface treatment equipment of the second embodiment is installed in a metal plate manufacturing step and is applied to the production of a metal plate having excellent surface characteristics. For example, at least one of the upstream and downstream sides of the quenched and tempered rolling mills arranged at the rear stage of the hot-dip galvanized steel sheet production line and at the rear stage of the continuous annealing production line is used to produce hot-dip galvanized steel sheets and cold-rolled steel sheets with excellent surface characteristics. So it ’s best to

Description of the Invention (44) '^ The surface treatment equipment of Embodiment 2 is used in combination with the quenching and rolling mill, but it can also be used only for hot dip plating The steel sheet manufacturing line and the continuous annealing manufacturing line are arranged for 5 weeks, and the surface treatment equipment of Embodiment 2 is installed on another line, and the surface treatment is performed by batch processing. The hot-dip galvanized steel sheet shown here is a hot-dip galvanized steel sheet, a hot-dip galvanized steel sheet, a hot-dip galvanized steel sheet, a hot-dip galvanized aluminum alloy sheet, and the like. The surface characteristics refer to surface characteristics related to the quality of a metal plate, such as press formability and vividness after painting. 'Example 1 shows the results of adjusting the surface roughness of a cold-rolled steel sheet having a plate thickness of 0.8 mm and a plate width of 1 200 mm using an apparatus having the configuration shown in FIG. 12. As the sprayed solid particles, spherical particles of SUS304 having an average particle diameter of 85 were used. The target surface roughness of the Nikkei steel plate is the average roughness Ra (jISB〇614) ^, which is ι · o // m. The diameter of the rotor of the injection device is φ 33 0ππ] and the number of rotations is set to 3600 rpm. At this time, the conveying speed of the steel sheet is set to 30 m / min, and the spraying amount per unit time of each spraying device is 120 kg / min, and the amount of solid particles sprayed per unit area is sprayed to 0 kg / m2. Conditions for spraying. A steel plate sample was taken for both the case of using the gas injection device and the case of using the gas injection device installed in the injection device in this state. Fig. 15 shows the distribution of the average roughness Ra (jisb6141) in the plate width direction of the sample taken. It can be seen that the flatness roughness Ra of the steel plate manufactured without using the gas injection device is only about 0 / zm at the maximum, and there is a large error in the plate width direction. On the other hand, it can be seen that steel manufactured using a gas injection device

536455 V. Description of the invention (45) " --- Plate: The average roughness is about RaW.〇㈣, and the plate width direction is given the uniform surface roughness. From this, it can be seen that when the gas injection device is not used, the solid particles flying in the injection chamber are accumulated on the steel plate, and the surface roughness = lower IV and the direction of the visibility are not uniform. The mechanism is on the entry side of the spray device, which can effectively impart uniform surface roughness. Example 2 shows the results of adjusting the surface roughness of a thermally sub-zinc steel sheet having a plate thickness of 0.75 mm and a plate width of 12 0 mm without using the equipment having the structure shown in FIG. 13. As the sprayed solid particles, spheroidal particles of §1] §304 with an average particle diameter of 85 # m were used. The target surface roughness of the steel sheet at this time is an average roughness Ra and is j · 2. The rotor diameter of the injection device is φ33mm, and the number of rotations of the motor is set to 3000rpm. At this time, the conveying speed of the steel plate is gradually increased from Ompm to 50 mpm from the beginning of the line operation, and the stage is decelerated before the production line is stopped. Even if the conveying speed of the steel plate is changed, solid particles per unit area are still made. The injection amount is 5 kg / m2, and the particle supply amount is controlled by a dosing device according to the conveying speed. Moreover] At this time, using the light-light sensing benefit of detecting the reflected light of the light source provided on the entrance side of the injection device, when the intensity of the reflected light is reduced, it is desired to make the air expelled from the gas nozzle proportional to the decrease in the intensity of the reflected light. The flow rate and the flow rate discharged from the suction port are increased, and the opening and closing of the solenoid valve and the opening degree of the regulator are controlled to adjust the surface roughness (Example A), and the flow rate discharged from the gas nozzle and the suction The inhaled flow rate is set to a constant value (Example B), and the results of surface roughness adjustment are compared.

In Practical Example A, the reflectance calculated from the intensity of the reflected light detected by the light receiving sensor is controlled to a minimum air flow rate of 0.9 or more even if the conveying speed of the steel sheet is changed. On the other hand, in Example B, the operation is often performed with a large air flow. Fig. 17 shows the distribution of the average roughness h in the plate width direction of the sample taken in the area measurement of the accelerated steel plate transfer speed in the case of Examples A and B = results. It can be seen that in Example A where the air flow rate is less controlled, a uniform surface roughness in the width direction can be ensured. That is, by using a sensor for measuring the intensity of the reflected light to control the air flow rate, a desired surface roughness can be obtained even with a small air flow, and therefore, the running cost can be reduced. 0 (Embodiment 3 ) FIG. 18 is a view showing an example of Embodiment 3-1, and shows a row of equipment for adjusting the surface roughness by the spraying room 205 while continuously conveying the metal plate 201 ′. For metal, cold rolled steel sheet or galvanized steel sheet is generally used. In the case of cold rolled steel sheet, it is better to perform cold rolling and continuous annealing to adjust the mechanical properties. In addition, "in the case of imparting surface roughness to a hot-dip galvanized steel sheet", it is suitable for those who are subjected to cold rolling, annealing, and galvanizing and then temper-rolled. However, 疋 'may be subjected to tempering rolling after passing through this production line before being subjected to tempering rolling. In addition, the metal plate 201 is not limited.

Accelerate the compressed air in the micro-slit nozzle, at the same time, entrain the solid particles 24 i and accelerate the solid particles, and spray them towards the metal plate. ,

On the other hand, in the case of a centrifugal rotary spraying device, solid particles are stored in a feed box 241, and a blade 244 is rotated by a drive motor 245. The solid particles 240 are accelerated toward the metal plate by being accelerated by the centrifugal force of the blade. 1 In the case of an air jet device, even if the average particle diameter is small, solid particles can be greatly accelerated. However, it is difficult to increase the spray area. Therefore, there are multiple Necessary for micro slit nozzle.
