以往之連續熔融金屬鍍敷裝置係採用，使欲鍍敷之鋼 板連續的通過由熔融金屬所成之鍍敷浴中，在鋼板之表面 產生與鍍敷浴構成元素之化合物，同時堆積鍍敷浴構成元 素本身之方法β而在浴中所使用之輥及元件即使甩余羼材 料，一般乃使用耐蝕性優異之鑄鐵，不銹鋼，高鉻鋼等之 鐵鋼材料。惟這些材料也在長期間使用時，即發生由熔融 金屬之腐蝕作用及摩擦所致之摩耗。即以金屬而言對於溶 融金屬無法做到絕對沒有腐蝕，因此浸漬於金靥浴中而使 用之金屬元件必在運轉操作中發生由熔融金靥所致之腐蝕 損耗，浴中元件乃急速地會摩耗。所以有很多利用熔射法 ，化學蒸著法，物理蒸著法將金臑表面以種種之耐蝕性金 屬，金屬陶瓷，陶瓷等來被覆以提高耐蝕性或耐摩耗性之 提案及嘗試。例如日本專利公報特開昭6 1 — 3 7955 號乃掲示利用水等離子熔射陶瓷，以製造對於耐蝕性、耐 熱性、耐摩耗性優異之金屬浴用輥之技術。特開昭 6 2 - 1 2 7 4 5 7號公報即揭示，以雷射光線照射以資 本紙張尺度適用中國國家標準（CNS ) 格（210X297公釐）-4 - 經濟部中央標準局具工消费合作社印製 44824 2 A7 _五、發明説明（2 ) 一部份地熔融形成於金靥基材之表面之陶瓷或金屬陶瓷之 被膜，由而提高金羼基材之高溫耐蝕性之技術。 上述之連續熔融金靥鍍敷裝脣乃需要大型之鍍敷浴槽 ，欲變更鍍敷浴之組成時即須更換大量之鍍敷浴*因此適 合於單品種大量生產，而對應於多樣化之鋼板之需求上即 經濟上不合宜。 因此有人提案如特開平4 一 2 4 7 8 5 7號公報所揭 示之不使用鍍敷浴槽之輥被敷方式，或使用小的鍍敷浴槽 之空中罐方式。 輥被敷方式乃使鋼板不通過鍍敷浴槽地，將沾於被敷 輥之表面之熔融金屬附著於鋼板，由而實施鍍敷，而多餘 之熔融金屬乃藉由很淺之熔融金靨回收用承盤所回收再使 用。在輥被敷方式中所使用之輥乃不與以往之鍍鋅輥或導 輥一般地浸漬於鍍敷浴中而使用，不過是輥表面之一部份 浸漬於浴之程度。而使用以往之金屣材料之輥時即由於熔 損或摩耗損傷很大，因此輥與鍍敷鋼板之間隙保持於一定 間隔這件事乃成爲不可能。因此須要選用熔損或摩擦損傷 較少之材質，可考慮將陶瓷形成於鐵鋼材料之輥乃元件之 適用。 在鐵鋼材料之表面形成陶瓷膜之方法有，CVD * P V D或熔射法等等很多方法被開發。惟這些之表面處理 被膜會有很小之針孔之存在。因此通過此針孔而熔融金屬 會浸入，不但會腐蝕基材，發生表面被膜之剝離》非常不 安定且缺乏可靠性。所以須受形成緻密且密著性良好之表 (請先W1*背面之注意事項再填转本頁 訂 本紙張尺度適用中ΒΒ家標车（CNS Μ4规格（2丨ΟΧ2!>7公釐） -5-

Description of the Invention (1) (Field of Invention) The present invention relates to a roller, an element and a manufacturing method thereof, and a continuous molten gold alloy plating device, and a method for operating the same. The molten metal is in contact with the steel plate, and the rollers and components of the molten metal plating device for plating (electroplating) on the surface of the steel plate, and the molten metal plating device using these (previous technology), Central Industry and Commerce Bureau, Ministry of Economic Affairs Printing (铕 Read the precautions on the back before writing this page) In the past, continuous molten metal plating equipment was used to continuously pass the steel plate to be plated through the plating bath made of molten metal. The surface produces compounds of the constituent elements of the plating bath, and the method of depositing the constituent elements of the plating bath at the same time. The rollers and components used in the bath are generally cast iron, stainless steel, and high corrosion resistance, even if the remaining materials are thrown away. Iron steel materials such as chrome steel. However, when these materials are used for a long period of time, wear caused by the corrosion and friction of molten metal occurs. That is, in terms of metals, there is absolutely no corrosion of molten metals. Therefore, metal components used in immersion in gold baths must cause corrosion loss caused by molten gold baths during operation. The components in the bath will rapidly Wear. Therefore, there are many proposals and attempts to improve the corrosion resistance or abrasion resistance by coating the surface of gold tincture with various corrosion-resistant metals, cermets, and ceramics by using the spraying method, chemical evaporation method, and physical evaporation method. For example, Japanese Patent Application Laid-Open No. Sho 6 1-3 7955 shows a technique for manufacturing a metal bath roll excellent in corrosion resistance, heat resistance, and abrasion resistance by using water plasma to spray ceramics. Japanese Patent Application Laid-Open No. 6 2-1 2 7 4 5 7 reveals that China National Standard (CNS) grid (210X297 mm) is applied to the capital paper scale with laser light irradiation-4-Industrial Standards Bureau of the Ministry of Economic Affairs Printed by the cooperative 44824 2 A7 _V. Description of the invention (2) A technology that partially melts the ceramic or cermet film formed on the surface of the metal substrate to improve the high-temperature corrosion resistance of the metal substrate. The above-mentioned continuous molten gold tin plated lip requires a large plating bath. When changing the composition of the plating bath, a large number of plating baths must be replaced. Therefore, it is suitable for mass production of a single variety and corresponds to a variety of steel plates. The demand is economically unsuitable. Therefore, some people have proposed a roll coating method that does not use a plating bath, or an air tank method that uses a small plating bath, as disclosed in JP-A No. 4 2 4 7 8 5 7. The roller coating method is such that the steel plate does not pass through the plating bath, and the molten metal adhered to the surface of the coated roller is adhered to the steel plate, thereby performing plating, and the excess molten metal is recovered by very shallow molten gold. Recycled with the plate. The roller used in the roll coating method is not used to be immersed in a plating bath in the same way as conventional galvanized rollers or guide rollers, but is only a part of the surface of the roller immersed in the bath. However, when using a conventional roller made of a gold-plated material, it is impossible to maintain a gap between the roller and the plated steel plate due to the large melting or abrasion damage. Therefore, it is necessary to select a material with less melting or frictional damage, and consider the application of ceramics formed of iron steel materials to rollers as components. There are many methods for forming a ceramic film on the surface of iron steel materials, such as CVD * P V D or spraying methods. However, these surface treatment coatings will have small pinholes. Therefore, the molten metal will penetrate through this pinhole, which will not only corrode the substrate, but peel off the surface film. It is very unstable and lacks reliability. Therefore, it is necessary to form a dense and good adhesion table (please note on the back of W1 * before filling in this page to modify the paper size applicable in the BB family standard car (CNS Μ4 specification (2 丨 〇 × 2!) 7 mm) ) -5- Printed by the Central Labor Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, 4482 4 ^ Λ7 __B7 V. Description of the invention (3) The surface film. Therefore, it is appropriate to combine the substrate and the surface film with a chemical reaction. To form a dense The ceramic film (nitride, boride, carbide layer) has the following methods. The method for forming a nitride layer is soft nitriding or ion nitriding. The most common method. The method for forming a boride layer is powder impregnation. Boron treatment (for example, the lecture of the Japanese Society of Metallurgical Materials: 1971-10) * and treatment with molten salt immersion boron method (for example, the lecture of the Japanese Golden Hurricane Society: 1-9 7 2-4) and so on. Methods include heating in a halide-containing gas to cover the hafnium carbide (for example, Einige Eigenschaften der Werkstoffkorabination Stahl mit Titankarbiduberzug, Metalloberflach 1 4 (1 960) 229)), or melting in a melting bath for shaping In the face of carbide metal, it is impregnated with iron and steel material, and the iron and steel material diffuses carbon and combines it with gold alloy to form carbides (for example, Niigata, Metal Materials 13, 3 (1973) 98), etc. These are applicable to the rolls in the bath of the plating line of the actual machine (Japanese Unexamined Patent Publication No. 7-188884) (problems to be solved by the present invention). In the molten metal plating device of the roll coating method, if the surface of the roll is When it is not wet with molten metal, uneven plating adhesion may occur. Therefore, for practical application of the roller coating method, the surface of the roller needs to be easily wetted with the molten metal. This paper standard is applicable to Chinese national standards ( CNS) A4 grid (210X297 mm) ~ (please fill out the notes on the back of Mit before filling in this page) -Reorder · 4482 4 2 Printed by the Consumer Sample Cooperative of the Central Procurement Bureau of the Ministry of Economic Affairs Λ7 B? 4) In the past, when a roller was immersed in a molten gold-plating bath, in order to prevent the surface of the roller from being eroded by the molten metal, the surface of the roller was not required to be wetted by the molten metal. The required roller. Roller On the contrary, the rollers in the plating system of the coating method are required to have the easy wettability with molten gold. Therefore, the conventional rollers for the molten metal plating equipment cannot be directly applied to it.

Description of Invention (13) The molten metal storage unit can be used for shovel (plating). The end of the body of the plating roll 3 2 is provided with an upper side plate to leak molten gold from both sides of the roll. The molten metal overflowed from the molten metal bath 16 passes through the upper surface of the plating roll 3, and The molten metal plate 5 is recovered, and the liquid level of the recovered molten metal 1 7 on the molten gold plate 5 is controlled to be a portion of the lower part of the plating roller 3 and the plate 1 outside the plate width. A part of the lower side plate 7 of the lower part of the coating roll 3 can be immersed in the recovered molten metal 17 so that the space and the environment of the upper part of the plating roll 3 can be cut off to make it an oxidation-free environment. The inert gas is sprayed from the nozzle 9 to spray argon or nitrogen, and the side molten metal carrier 8 is used for recovery, thereby preventing leakage of molten metal from the plate width of the plating roller 3 and the steel plate 1. In the lower part of the molten metal tray 5, a space 12 is continuously arranged in the nostril 13 of the non-gasified environment. In the space 12 is provided a turning roller 1 1 for changing the direction of the steel plate 1 to the vertical upward direction. A heat corrector 10 for correcting the bending of the steel plate 1 is provided above the steering roller 11, but this is not necessary. Furthermore, as shown in the flow direction indicated by the arrow in the figure, the molten metal recovered in the molten metal holder 5 and the side molten metal holder 8 is returned to the molten metal circulation tank 1 through the molten gold recovery pipe 18. 4 »In this example, a dross recovery device 19 for decomposing, oxidizing, floating and the like is installed in the middle of the molten metal recovery pipe 18. The molten metal 21 passed through the dross device 19 is entered into the molten gold alloy circulation tank 14 and is supplied to the molten metal bath 16 by the molten metal supply pump 15 and the molten metal supply pipe 20. The plating thickness of the steel plate 1 is adjusted by the ejector 2 for adjusting the plating thickness.

Description of the Invention (14) Among the components used in the molten metal plating device, the body of the plating roller rotating while contacting the plating bath and the steel plate has a lot of melting loss and wear. When the damage and wear are progressing; the gap between the roller and the steel plate cannot be fixed during the running of the steel plate, so it is impossible to perform a stable operation. Therefore, preventing the melt loss and wear of the components in the bath is an important issue for the continuous implementation of plating operations. Materials that do not wet with molten metal are very suitable. On the other hand, when the roller is applied, it is different from the conventional case where the plating operation is performed in a plating bath. The surface of the roller is used to transfer the plating. The bath is carried out, so the roll and the molten metal need to be wetted. A roll that has both the excellent melt-loss resistance to the molten metal and the opposite properties of wettability is required. "Plating rolls are generally very large, so Roll It is not economical to use all ceramics for making, so only the necessary part of the surface can be achieved by ceramization. In the application of the method of the present invention, the material of the roller base material is not limited, and to the extent that surface treatment is possible In general, iron and steel materials can also be used. Furthermore, as for the material of ceramics, as long as it is a material that has excellent melt loss resistance to molten metal and can be wetted, there is no special limitation. The embodiment of the present invention is described. (Example 1) In this example, in order to confirm the effect, as an object equivalent to a roller, carbon steel (S45C) for construction was processed into an outer diameter of 60 mm * an inner diameter of 4 2 mm, and a width of 2 After the cylinder of Omm, it is buried in the boronized powder containing carbonization as the main component, and it is kept at 90 in an argon atmosphere (please read the precautions on the back before filling this page).

Description of the invention (15) The gaseous boron was diffused into the gold steel in 10 hours at the temperature. Selenium iron pottery formed on the surface The test piece β of the film is shown in Fig. 2 as a result of investigating the hardness near the roller surface. The vertical axis of Fig. 2 represents micro-Vickers hardness, and the horizontal axis of Fig. 2 represents the distance from the surface of the roller. It is the hardest on the surface. As it gets lower inside, it becomes the hardness of the substrate at about 150 / ζιη from the surface. This means that the depth of diffusion and immersion of boron is about 150 from the surface. The reason is that the compound with a different composition from the base material. The results of investigating the compound layer by X-ray foldback, and knowing the compound of iron and boron "detailedly means that F e B is mixed on the surface, and F eaB enters the internal F. The smaller e B is, only Fe2B remains. From the surface 1 50 # m, there is only a — Fe (please read the notes on the back before filling in the K yellow). Cooperative Du Printing (Example 2) For the test piece used in Example 1, a boron-iron ceramic film was formed on the surface, in a zinc plating solution maintained at 470 ° C, at a peripheral speed of 2 Om / mi η while rotating and holding for 100 hours, the latter investigated the surface wetness and melting loss caused by the zinc plating bathAs a result, no adhesion of the zinc plating bath and melting loss were observed on the surface of the test piece after the test. In the comparative example, a test piece before the formation of the iron boride ceramic film was used, and the same test was performed. Results The diameter of the test piece was reduced in 25 hours. 64mm, 0.90mm in 50 hours, 1.14mm in 75 hours, and 1.32mm in 100 hours. The iron-zinc reaction layer was seen on the surface. It can be seen that iron boride ceramics are formed on the surface. The paper size is applicable to the Chinese National Standard (CNS) A4 pit (210X297 mm). -18-Printed by the Shell Industry Consumer Cooperative of the Central Sample Bureau of the Ministry of Economic Affairs Λ7 _B? Explanation of the invention (16) The stability of the test piece of the film to the zinc plating bath. Fig. 3 (a) Scanning electron microscope photograph showing the cross section of the surface of the test piece of the comparative example. Between the ceramic layer and zinc The existence of a clear interface. It can be seen that the wettability is poor. The resin above zinc is the resin in which the test piece for observation is embedded. Figure 3 (b) shows the "Broken surface of the test piece of the example" A scanning electron microscope photograph of the surface. There is no clear interface between the ceramic layer and zinc, and it is known that there is good wettability. (Example 3): In Example 1 | Boron was formed on the surface The test piece of the iron ceramic film was placed in an atmospheric furnace at 350 ° C for 5 hours. The surface layer was oxidized. The test piece after the oxidation treatment was placed in a zinc plating bath maintained at 470 ° C and rotated at a peripheral speed of 20 m / mi η. After being held for 100 hours, the zinc plating bath was investigated. Wetness and melting loss on the surface. As a result, although the zinc plating bath was adhered on the surface of the test piece, no melting loss was seen. * The surface layer of the oxidized test piece was marked with X before the test. Result of investigation based on line foldbacks * From the surface to 50 #m, the proportion of F e Β is relatively large. Although the relatively porous part is observed with F e3 04 and B 2 0 3, it is F e2B from the inside. No F e304 or B2 03. Using X-ray foldback to investigate the surface of the test piece from which the zinc plating bath was removed after the test, it was found that there was a compound Z n F e 204 and in other words borrowed before the test. In the test, F e 204 formed by oxidizing the surface, in the test, reacted with zinc to produce a Z n F e 204 compound, which caused wetness. However, although the above-mentioned reaction occurs in the surface layer, only This reaction only occurs on the polar surface layer, and it is still internal (read the precautions on the back before filling in the buttercup) National standard rate (〇 «) 6 4 grids (210 fathers 2 mm) -19- 4 2 a?

Description of the invention (17) 2B exists as a bone, so the reaction will not proceed, and the melting loss will no longer proceed. After the test, the surface analysis of the zinc near the surface of the test piece by S EM and EDX showed that the zinc system had a high concentration of about 20 from the surface. Ground invasion, and local infiltration can be seen up to 5 0 // m inside, but there is no zinc infiltration from within 50. * · As mentioned above, the zinc plating bath is attached and the plating may be transferred. Because the surface is porous, the molten metal immersed here is easily fixed by the wedge effect, so it is very suitable for the transfer of the plating bath. (Example 4) As a result of carrying out a transfer test of a zinc plating bath using a simulation and roller having a diameter of 10 mm and a length of 20 mm made in the same manner as in Example 3, it was understood that a stable transfer amount was required 2 ~ 3 hours of tame operation "This is due to the reaction of Fe 300 and Z η to form Z n Fe 200. The porous part of the surface is filled with a zinc spatula bath, and the wedge effect To achieve sufficient transfer of the zinc plating bath, it is necessary to tame the operating time, but the industry is required to be able to move to a steady operation in a short time. Therefore, in order to accelerate the reaction speed, the F e304 formed on the surface is reduced to promote the reaction with Zn. This embodiment will be explained below. A simulation roller with a diameter of 100 mm and a length of 200 mm will be manufactured in the same manner as in Example 3. The roller will be freely installed on the lathe, and a width of 200 mm will be installed on the tool table. Hexane heater. While pre-heating the roller while rotating the surface to a surface energy of approximately 450 ° C, the paper of the roller is sized in a general and difficult country. {CNS) A4 «l grid (210X297 mm) ^ '{婧 先Read the notes on the back and fill in this page again.) 448242 V. Description of the invention (18) Part of the plate can be set with molten zinc in contact with the molten zinc bath of 470 eC. "Rotate the roller at 2 rpm to heat The reducing flame part of the device can touch the surface of the roller near the surface of the molten zinc and bring it close to the surface of the roller for reduction treatment. The surface of the reduced roller is immersed in molten zinc between oxidations. * As a result of the transfer test of the zinc plating bath performed on the roll, the test was started at the same time as the roll temperature became the bath temperature. As a result, the transfer thickness of the plating bath was constant and stable after the test was started. The effect can be confirmed. . Further, instead of the reduction flame of the heater, the surface of the Fe 300 film was coated with a highly reducing flux, and the same test was performed, and the same results as those obtained when the reduction flame was used were obtained. From this, it can be known that before the molten metal is brought into contact with the element of the continuous molten metal plating device, it is desirable to heat the surface of the element by heating. It is also advisable to attach a reducing agent to the surface of the element before bringing the molten metal into contact. (Example 5) Printed by the Shellfish Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economics (for zinc, read the precautions on the back and then fill out this page) Because it is predictable that the iron boride system will react with molten aluminum, On the surface of the sample in which the iron boride ceramic film was formed in Example 1, an aluminum film of about 10 〇 # πι was formed by a reduced-pressure plasma spray method, and a reducing flame of a butane heater was used to melt the surface. The aluminum was reacted with iron boride to decompose it into aluminum boride and iron. The sample was held in a zinc plating bath at 4 7 Ot and rotated at a peripheral speed of 200 m / mi η. Wetness and melting loss of the surface of the zinc plating bath after hours. As a result, the adhesion of the zinc plating bath was confirmed on the surface of the test piece after the test, but the paper size does not use the Chinese National Standard (CNS) A4 specification (210X297 mm) -21-4 ^ 82 /: · λτ B? Printed by the Central Consumer Bureau of the Ministry of Economic Affairs and Consumer Cooperatives. 5. Description of the invention (19) Melt loss was observed, and the surface of the iron boron ceramic film was oxidized and zinc was sprayed on the surface. Show the same effect. (Example 6) A plating roller having a diameter of 20 mm and a body length of 230 mm and a total length of 6 50 mm was produced in the same manner as in Example 3, followed by the reduction flame treatment of the heater described in Example 4, using the drawing. The zinc plating simulator of the roller plating method constituted by the roller shown in FIG. 1 was used to plate a steel plate having a thickness of 0.8 mm and a width of 200 mm at a linear speed of 30 m / mi η. The results were obtained and used. In the past, large galvanized baths had no difference in quality of the galvanized steel sheet, and the zinc plating simulator was used to perform intermittent operation for 10 hours and no-load operation for 90 hours without observing roller damage. (Example 7) A plating roller having a diameter of 20 mm, a body length of 230 mm, and a total length of 650 mm was produced in the same manner as in Example 3, and was in contact with the end face of the light body, and each other as the roller was rotated. The rubbed side plate was also subjected to surface treatment in the same manner as in Example 3. The roller and the side plate were assembled in the simulation machine used in Example 6. As a result of the test, the contact and sliding portions of the roller and the side plate were abraded. Since there is no abnormal phenomenon such as vibration, it can be judged that smooth rotation was performed with low friction. We also evaluated the reduction treatment or the application of reductive flux on the side plate in the same manner as in Example 4. The same result was obtained and the effect was confirmed * (Please read the precautions on the back before reading Fill out this page > This paper size applies to Chinese National Standards (CNS > A4 size (2 丨 0X297mm) -22- 4 Printed by the Bayer Consumer Cooperative of the Central Standards Bureau of the Ministry of Economy 4 __B? V. Description of the invention (20 ) Moreover, the side plate 1 is also evaluated for only the treatment of Example 1. It also shows a situation of low friction and low friction. However, when only the treatment of Example 1 is performed for the roller and the side plate, that is, The contact sliding part between the roller and the side plate shows that the friction also vibrates and cannot be smoothly rotated. (Embodiment 8) For a diameter of 200 mm and a body length of 230 mm made in the same manner as in Example 1, a total length of 650 mm The plating roller and the side contacting the roller with the body end surface and rubbing against each other as the roller rotates. After the isotropic carbon sintered body with solid lubricity is divided and processed into segments with a dovetail shape , Mechanical processing on the surface of the side plate. The same experiment as in Example 6 was performed to evaluate the sliding characteristics. As a result, friction and no abnormalities such as vibration were observed on the contact sliding portion between the roller and the side plate. Therefore, it can be judged that smooth operation was performed with low friction. For the replacement of the carbon sintered body, a combination of a carbon fiber / carbon composite sintered body was used for evaluation, and the same sliding characteristics as when the isotropic carbon sintered body was obtained> (Example 9) are shown in FIG. 1 The components that come into contact with the molten metal and the components that are in contact with the molten metal used for the molten metal circulation will also suffer from melting loss and sliding wear. Therefore, the length of the molten metal transfer pipe with a maximum length of 2m and an internal diameter of 60mm (equivalent to The piping 18 for molten metal recovery in FIG. 1) and the pump used in the system (equivalent to the pump for molten metal supply 15 in FIG. 1 (for the first note on the back, please write this page again) Applicable to Chinese National Standards (CNS M4 specification (210X297 mm) 23-Printed and printed by Shellfish Consumer Cooperatives, China Standards Bureau, Ministry of Economic Affairs ^ ^ ^ Λ7 __V. Description of Invention (21)) Also implemented and implemented The same surface treatment as in Example 3 was used in the experiment of Example 6 = this result, no friction was seen in the part in contact with the molten zinc, and the friction (friction) part also showed low friction and low friction. It was confirmed that the pipe which only circulates molten metal has the effect of applying only the treatment of Example 1. As described above, in the molten gold-plating apparatus, the elements in the bath are generally iron-steel metal. Since its corrosion resistance and abrasion resistance are poor, in this embodiment, for example, when a ceramic film with good pinhole-free adhesion is formed, and a new compound having a composition that reacts with its molten metal is produced on its surface, it is doubled. In order to achieve a structure that makes the components in the bath have corrosion resistance, abrasion resistance and wettability with molten metal "according to the embodiment, it is unnecessary to use a large plating bath tankless plating In the continuous molten metal plating device of the device, a ceramic film having a corrosion resistance is formed on the surface of a component used in a bath such as a roller used in the molten metal plating bath, and at the same time, it can make contact with the molten metal. The molten metal can be stick to the roller surface and roll surface of the coating to be transferred Shiru. Furthermore, the film obtained in the embodiment is very dense and has good adhesion to the iron steel material of the base material of the roller or the element, so that a high-reliability long-life bath element can be obtained. Furthermore, as a result of using the plating roller or element according to the embodiment, it is possible to achieve a stable operation movement of the plating device of the roll plating type.
