Description of the invention (1) Printed by Zhongji Ministry of Industry and Economics, Beigong Consumer Cooperative Society This invention relates to the loading and unloading of molten metal barrels and in particular to the improvement of the bottom opening of the barrel (for example, a pouring bucket). The valves placed below the liquid discharge tank of the barrel include movable valve parts with flow passages, which are displaced from each other when the valve is in the closed position, and are substantially aligned with each other in the open position of the valve , So that the melt can flow out of the barrel through the flow path. This type of valve and its external equipment are called sliding gate systems and can be obtained in several new styles, including those in which the valve member tracks a linear relative movement and the valve member tracks a relative rotational movement. Examples of such valves are described in WO / 87/07306, among other instructions. The present invention will be further described below on the pouring bucket. In the bottom of the pouring bucket, there is an outflow hole leading to the sliding washing valve system. To prevent the melt from flowing down into the valve, solidifying and blocking the liquid drain, the outflow hole is usually filled with sand. Despite being filled with sand, it is still an important moment when the drain valve on the hopper filled with molten steel is about to open to allow steel to flow into the steel making process of the casting mold or funnel. What happened in some cases was that the steel did not flow out due to some form of blocking relationship in or in the pipeline connected to the outflow hole. The absence of natural flow of molten metal when the valve is open can cause a series of economic and environmental problems. Under normal circumstances, the melted liquid flows out of the ladle through a protective line that prevents air from contacting the liquid steel. When the liquid drain is blocked, this protective line must be removed so that the oxygen combustion equipment can be approached to clear this blockage. Then, a sample of the tube connected to the oxygen pipeline is manually fed into the liquid discharge tank so that the blockage can be burned out. During the implementation of this action, molten steel and slag will be splashed in the outflow hole (please read the note $ item on the back and then fill out this page) ί% The speed of this paper is the speed of the Chinese National Standard (CNS > A4 specification (2 丨 〇 > < 297 mm) V. Description of the invention (2) A7 B7 Zhong Ji Φβ-Zhongyuan Garden of the Employee Consumer Cooperative of the Central Committee, and when the obstruction is cleared, the molten steel flows rapidly The method flows into the funnel near the operator. The risks associated with this operation are quite obvious. In addition to the oxygen collision and the cost of oxygen, this operation may increase the consumption of refractory materials that constitute the liquid discharge tank. A clogged ladle takes time, and the best casting speed from the funnel to the mold cannot be achieved, so that it may produce steel with deteriorated quality. The worst case is that the casting must be stopped and new castings are started. Various subsequent preparations and reheating of the steel in the ladle. It was once proposed to blow argon gas into the drain before opening the sliding wash port, by which method the tank can be pressurized so that the cover can be removed High-temperature sintering of outflow holes Shell, or steel that may have solidified. The argon gas in this proposal has been introduced into the lower part of the liquid discharge tank at the closed position of the valve, and under large resistance, it must be forced upward through the entire sand column in order to reach this liquid discharge tank The upper part. During the trial period of this proposal, the sand has been blown away, and the molten steel has flowed into the drain tank and had time to solidify before the valve can be opened. Even sealing has become a major problem ^ If so, because many The reason is that the outflow of natural molten metal must be coordinated with the opening of the pouring valve, and the purpose of the present invention is to provide this improvement. Thus, the present invention is based on the use of gas, and argon is preferred, and a device will be used This argon gas is introduced into a relatively high position in the liquid discharge tank. During the implementation of this procedure according to the present invention, a tube that is relatively easily broken is introduced into the liquid discharge tank, and when the valve is in the closed position, the tube is in The groove protrudes from the two parts of the valve. Then the gas is blown in through the tube, so the valve is opened, and the tube breaks during this period.

Description of the invention (A7 B7 Printed by the Consumer Labor Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Before the steel liquid flows, the tube has been folded and the prostitute sand flows out. Therefore, from the point of view, the present invention can provide a device that can open and close the outlet in the molten metal loading and unloading barrel, the barrel contains a The port is in communication with the outlet and has a relatively active material. The parts between these have a mutual displacement to close the valve and, therefore, the openings of the port A, and these openings are in communication with each other and with the outlet It is connected to open the outlet, so that the molten metal can flow out from the loading and unloading barrel. It is characterized by providing a fragile tube through which the gas can pass. This tube has a length enough to allow it to extend from the two parts of the valve Out and extend into the outlet of the loading and unloading barrel, so that the gas can be sent into the outlet, and then the valve is opened by the relative movement of the components of the valve to break the tube, so that it does not hinder the opening, and lies in one of the tubes The end has a cup-shaped seat portion so that it can be matched with a similarly shaped recess in or near the valve. On the other hand, the present invention can provide a method of opening and closing the outlet in the molten metal loading and unloading barrel.

Description of the invention (4) The Negative Work Consumer Cooperative of the Ministry of Economic Affairs of the People ’s Republic of China prints a very fragile tube, for example, it can extend from a part of the valve ’s moving parts to the other side of the valve ’s opening, namely its flow path, and Pass upwards through the opening in the fixed part of the valve, the passage. The cup-shaped seat portion of the frangible tube can be conveniently placed in a correspondingly shaped recess in the connector, and the connector is attached to the lower part of the valve, that is, the movable valve part of the sliding gate valve. The cup-shaped seat portion may be roughly hemispherical or partially hemispherical, for example, and for convenience, each specific example will be described later. Nevertheless, it should be understood that the present invention is not limited to these particular shapes. The hemispherical seat portion at the end of the tube is compared with the diameter of the tube itself, and the larger diameter is preferred. In this way, the hemispherical seat portion can form a spherical extension at one end of the tube, so that the pole of the hemisphere is farthest from the tube. The passage of the gas through the pipe or each passage must of course pass through the hemispherical part, or enter the pipe above it, but the former is more falcon. The end of the fragile tube, that is, the lower end does not need to be completely hemispherical in use and it is true that the shape of the seat part is better, so that the truncated hemispherical shape has a flat lower surface, and this one The device, as explained in more detail later, has been found to be very advantageous for the device regarding the passage of airflow through the tube. The present invention is advantageous in that it provides a fixing device that can move in an oblique direction than when the pipe is fixed, and that the pipe passes through the valve components to accurately align the frangible pipe with less movement. In this way, without the hemispherical seat, the pipe can still be fixed slightly away from the necessary pipeline, and it can be damaged during its installation or operation of the valve, so that it cannot perform its function as required at the critical time❶The present invention ~ 6 The size of this paper is not in the "Guo Qiang!

Description of the invention (5) A7 B7 Zhongji Ministry Central Rubbing Bureau Beigong Consumer Cooperative Printed can overcome this problem in a smart and effective way. Any misalignment with the necessary pipeline can be quickly accepted It is calibrated and can be adjusted by matching the seat device with a hemispherical shape. On the other hand, the present invention can provide a frangible tube with at least one longitudinal passage through which gas can pass, one end of the tube has a cup shape For example, the seat part of a substantially hemispherical shape can be fitted with a correspondingly shaped recess in or near the outlet valve of the molten metal loading and unloading barrel. The frangible tube is made of ceramic material. The ceramic material It can withstand the temperature of molten steel, and is easily broken when the valve is opened. The tube can be provided with several, for example four, axially extending gas passages along its entire length. The tube and its hemispherical protrusions can be molded or The mechanism is from a larger-diameter tube. Several small-diameter axial gas passage devices have the advantage that when the valve is opened, the gas tube ruptures, and the next section remains fixed in the movable plate of the valve. When draining the melt, the sliding valve must be closed, and the remaining section of the tube will form a plug, so that the remaining outflow area is limited by the hole or holes in the tube. Therefore, several The small hole, while allowing the gas "I" to pass, will prevent its passage through the solidification of the melt, and thereby prevent its own passage. As long as it passes through the valve's tube part, it will break when the valve is opened, The full length of the tube does not need to be fragile material. The rest of the tube, that is, the upper part can be, for example, metal. This metal tube can be installed in a suitable recess at the top of the fragile tube, or vice versa , Or press fit between the two ---------- 1 ------ ir ------ 0 (please read the $ item on the back before filling this page) The size of this paper is applicable to the «National Standard (CNS) A4« 1 grid (210X297 mm).

Description of Invention (7) System 6 is a unit that can be attached to the washing bucket and separated from it. The unit includes an upper shell 7 and a lower shell β, the upper shell 7 includes a refractory valve plate with a flow passage opening therethrough, and the lower shell 8 includes a refractory valve plate 11 having an outlet groove 12. The upper part of the sliding washing system 7 is arranged so that when it is in the position shown in the figure, it does not move relative to the washing bucket, so that the opening of the flow path is positioned coaxially at the position of the opening defined by the inner nozzle 5 , That is, it is coaxial with the liquid discharge tank 5a. In Figure 1, the sliding mouthwash system is shown in the closed position, the lower movable valve member 8 is positioned to the left, so that the outlet groove 12 in the valve plate 11 is biased to the flow passage opening 10 in the flow valve plate 9 The surface of the valve plate 11 is located at both ends of the liquid discharge tank 5a and closes the liquid discharge tank. As described in the sliding gate system, it is equivalent to the known similar system. According to the present invention, the gas pipe 13 passes through the lower casing 8 and the portion of the valve plate 11 that closes the liquid discharge tank 5a. The upper end of the gas pipe 13 extends into the upper portion of the groove 5a, and the lower end thereof is seated in the seat connecting member 14 supporting the lower side of the lower case. A gas source not shown in the figure can be connected to the gas skull tube via the joint 14. The gas tube 13 is quite fragile, that is, a relatively brittle refractory material. The lower end 13a of the gas tube 13 is in the shape of a truncated hemisphere, and is seated in a similarly shaped recess in the joint 14. Regarding this forming end of the gas pipe, it will be further explained below with reference to Sections 5 and 6. In the washing bucket, well block 4 and inner nozzle 5 above the tablet liner 2, there is a molten liquid (not shown in the figure) and, as is known, the liquid discharge tank 5a is defined by the nozzle 5 and filled with an appropriate amount Sand {not shown in the figure), the sand in the area in contact with the melt is sintered into a dome-shaped hard shell 15. When discharged from the washing hopper, the gas (argon gas is better) is blown through the joints · 14 ~ 9 ~ This paper standard speed is used in the Chinese national rate (CNS > A4 specification (210X297mm) ----- ----- ^ ------ 1Τ ------ 0 (please read "Notes on the back and then fill in this page") 5. Description of the invention (8) A7 B7 Central Ministry of Economic Affairs The industrial and consumer cooperation is du-printed to destroy the obstruction in the liquid discharge tank, that is, the sintered sand-hard shell 15, which is shown in a loose state in Figure 2. By; the liquid pipe extends upward to the liquid discharge There are quite a number of grooves 5a (measured from the bottom about three-quarters of the height of the rising nozzle, and it has been shown that good results can be obtained), the gas pressure is introduced just below the obstacle to be removed. In addition, most of the Sand will be left in the nozzle, so it can prevent the melt from pushing the nozzle downwards, which may cause the risk of solidification and blocking the liquid drain. "And the remaining sand will produce a downward pressure, which reduces the risk of leakage. However, it needs to At this time, a suitable gasket can be placed at the bottom of the opening 10 in the plate 9 to surround the tube 13 and seal between the plate 9 and the movable plate 11 The gasket should be a compressible, non-porous, high temperature resistant material, such as ceramic fiber material covered with a mica layer. Therefore, a gas pressure system will not affect the drive unit for opening the valve (not shown in the circle), such as hydraulic pressure The piston and cylinder unit, so the movable lower shell part 8 can be moved to the right as shown in No. 1 to open the nozzle hole unit. In this regard, the gas tube 13 engages the inner wall of the inner nozzle 5 and is cut in front of the lower edge of the latter. This position is shown in Figure 3. However, in fact, the gas skull tube will break earlier because the sand in the inner nozzle 5 will fix the part where it is inserted. At the same time the valve plate is broken! The insertion part of the upper gas tube 13 may be pushed to the position shown in FIG. 3. The continuous opening movement can open the coverage of the entire liquid discharge tank, so that the melt can flow out through the inner nozzle 5, through the flow passage opening 10, and then from the lower valve plate outlet groove 12. Here, the cut-off portion of the gas pipe 13 is performed separately along this. The remaining portion of the gas tube 13 in the lower shell portion 8 can be removed by releasing the adhesive fixing the joint member 14 on the lower shell portion 8 after the liquid discharge is completed. The frangible tube 13 is shown in great detail in both Figures 5 and 6. ～ 1 〇〜 ---------- ^ ------ 1T ------ 0 (please read "Note on the back of the item before writing this page]) This paper / ut applies Medium η® Family Car (CNS) A4 threatened (21 () > < 297 public envy) Printed by the Ministry of Economic Affairs Central Consumers ’Bureau Consumer Cooperative A7 ---________ B7 V. Description of invention (9) The curved surface of the truncated hemispherical seat portion 13a is formed so that it can be fitted with a similar curved recess in the joint 14. Due to the curvature of the fitting surface between the seat portion 13a and the joint 14, any misalignment of the necessary bend direction of this tube can be accommodated so that the tube will not be damaged during insertion through the valve and during insertion into the outlet. As shown in the figure, the pipe 13 has four axial gas passages extending from the top of the pipe and rising in the flat end face 13c of the frusto-hemispherical seat. As mentioned above, although the hemispherical seat does not necessarily need to provide a flat end surface, it may be found to be advantageous because the possibility that each hole 13b is blocked during the formation of the hemispherical portion is less than that which occurs in the crossbow area. For example only, the diameter of the tube Ί3 and the end face 130 may be about 8 mm, and the radius of the hemisphere may be about 8 mm, and the diameter of each axial channel is about 2 mm. The length of the tube can exceed 200 mm, for example from 350 to 700 mm. In the seventh section, the " floating mandrel " connection between the lower end of the frangible tube 13 and the lower side of the valve housing is shown. In this particular example, the cup-shaped end 13a of the frangible tube 13 is seated in a complementary recess in the upper surface of the floating mandrel. The mandrel 20 is installed inside the annular casing 21, and the casing 21 is clamped to the lower side of the valve member 8 by a base 22. Sealing the O-ring 21a allows the shell 21 and the base 22 to be sealed. The annular recess is bounded between the mandrel 20 and the inner wall of the shell 21. The cup-shaped lower end 13a is fixed to the lower side of the base 22 by a gasket 22a. The gas can be connected to the annular recess 23 and the mandrel 20 through a passage 25 from a gas source (not shown in the figure). The tube 24 of the base 13a of the tube 13 is introduced into the tube 13. ～ 1 -1〜 This paper standard uses the Chinese national flour rolling rate (CNS) A4 specification (210X297mm) I binding line (please read the note $ item on the back and then fill in this page) A7 __B7 V. Invention description ( 1〇) The plug 26 can close the lower end of the shell 21, and is sealed with the inner wall of the shell by the O-ring. The plug 26 has an upper annular shoulder 2β, and the upper periphery of this shoulder 28 can receive a stepped retaining ring 29. The lower part of the mandrel 20 has a depending central boss and an annular shoulder 31. The shoulder 31 is supported on the upper surface of the fixing ring 29, and the boss 30 protrudes from the fixing ring to leave an annular recess between itself and the ring. The vertically extending central configuration hole of the boss 30 can receive the legs of the inverted T-shaped connector or the box bottom 32. The "Ding Ding" crossbar is supported on the upper surface 26a of the plug 26, between but separated from its shoulders. This device allows easy assembly of the tube 13 and the arrangement of its seats in the shell 21. The annular recesses 23 and 29A allow the oblique movement of the mandrel 20 to one side so that it can "float" and cater to the vertical misalignment of the tube 3. This device cooperates with the correction feature of the cup-shaped end of the tube 13 Provide a most advantageous device. ---------- ^ ------ lτ ------ ^ (Please read the notes on the back before filling this X) Printed and printed by the Bureau ’s Consumer Cooperatives ~ 12 ~ This paper uses the Chinese national standard (CNS) A4 specifications (210X297mm)
