Description of the invention (/) Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs This invention relates to molten metal loading and unloading barrels and in particular to the improvement of the bottom opening of the barrel (for example, a washing bucket). The threshold placed under the liquid discharge tank of the barrel includes movable valve parts with flow passages. These passages are displaced from each other when the valve is closed. When the valve is in the open position, they are substantially mutually Aligned so that the solution can flow out of the barrel through the flow-out channel. Such a valve and its external equipment are called sliding gate systems and can be obtained in several new styles. And the valve parts track relative rotational movements. Examples of such valves are described in WO / 87/07306, among other instructions. In the present invention, the pouring bucket will be additionally described below. There is an outflow hole leading to the sliding gate valve system in the bottom of the $. 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 melting fun will open to allow steel to flow into the 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. On the valve: No natural flow of molten metal when opened will cause a series of economic and environmental problems. Under normal circumstances, the melted liquid flows out of the Jidoujing through a protective pipe for preventing air and liquid steel from contacting. 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 ^^^^ China National Standard (Fuyang) 84 specifications (210/297 mm) ---------- ------ Install ------ (Please read the precautions on the back and then this page) Order> m- m · l— In 312638 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Inventions Around (2), and when the obstruction is cleared, the copper liquid flows into the funnel near the worker in a rapid flow. The risks associated with this remake are quite clear. In addition to the cost of the oxygen bumper and oxygen, this operation may increase the consumption of fire materials constituting the liquid discharge tank. However, it takes time to beat the material, making it impossible to achieve the best casting speed from the funnel to the mold, so it may produce copper with deteriorated quality. The worst case is that the fabrication must be stopped and all subsequent preparations for the new front piece started, and the steel in the ladle must be reheated. It has been suggested that argon gas be blown into the silicon tank before opening the sliding gate. By this method, the liquid discharge tank can be pressurized, so that high temperature sintered sand covering the outflow hole can be prepared. Stray argon gas 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 sand column in order to reach the upper part of the liquid discharge tank β in the trial of this proposal During this time, the sand was blown away, and the molten steel had flowed into the drain tank and had time to solidify before the valve could be opened. Even sealing has become a major issue. · If it is due to Xu Da's reason, the outflow of natural metal melt must be matched with the opening of the bucket valve to add bismuth to improve, and the purpose of the present invention is to provide this improvement. In this way, the present invention is based on the use of gas, and argon gas is preferred, and the argon gas is introduced into a relatively high position in the liquid discharge tank by a device. During the implementation of this procedure in accordance with the present invention, a f which is relatively easy to break is introduced into the drain, and when the valve is in the closed position, the tube protrudes from the two parts of the valve in this slot. After that, gas was blown in through this tube, so the valve was snapped and the tube was broken during this period. Melt during the solution flow out of the furnace.-I.

Description of the invention (3. Before the steel flow flows, the broken end of the pipe is handled with the outflow of sand. M point of ϋ clearly can provide-a device to open and close the molten metal In the loading and unloading barrel, the barrel contains a valve that is in communication with the outlet and has relatively movable components, etc. This displacement is used to close the .. Therefore, the openings of the fine mouth, which are in communication with each other, and The π π is connected to each other, and the molten metal can be reduced from loading and unloading. The feature of the miscellaneous tool is that it provides a fragile tube through which the gas can pass. The length of the tube is sufficient to be from the two parts of the valve And reach the exit of the loading and unloading barrel, which can be fed into and out of the body, and then opened by the relative movement of the parts to break the tube so that it will not hinder the opening, and the end of the tube has a cup-shaped seat Part so that it can interact with the valve or near the que One of the similar-shaped notch pairing installation "• 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. A valve in the barrel is positioned so that it can be connected to the The outlet is connected, this valve has a relatively movable valve part and each opening of each valve part is displaced from each other, so that the valve and therefore the outlet can be closed, and the positions of these openings are set so that Communicate with each other and with the outlet to open the outlet, so that molten metal can flow out of the loading and unloading barrel. It is characterized by a fragile tube that is inserted into the outlet through the valve components when the valve is in the closed position. It is injected into the outlet through this tube to remove any obstacles in the opening, and the valve is opened to destroy the entire section of the tube, and there are two cup-shaped seat parts at one end of this tube to allow Paired with a similarly shaped notch in or near the valve. 1 paper wave New Zealand financial country country quasi (Nuo) eight 4 miscellaneous (2 献 297 公 #). ^ 1τ -------- ^ --- (please read the precautions on the back and then this page) · ^ -m .-ii · I-ml- V. Description of the invention (4) A7 B7, the Economic and Central Bureau of Economics and Social Affairs staff printed a very fragile tube for example, which can extend from part of the valve's movable part to the valve The other side of the opening is its flow path and the opening in the fixing member passing through the valve β upwards, that is, the cup-shaped seat portion of the passage β frangible tube can be conveniently placed in the correspondingly shaped recess in the connector, and this The connector is attached to the lower part of the valve, that is, the lower side of the movable valve part of the zip line r washing valve. The cup-shaped seat portion may be roughly hemispherical or partially hemispherical, for example, and for convenience. The specific examples will be described later. Although it should be understood that the present invention is not limited to these special shapes 0; the hemispherical seat portion of the pipe end is compared with the diameter of the pipe itself, and the larger diameter is more Good / so, this hemispherical seat part can form a spherical feast extension at one end of the tube, so that the pole of this hemisphere is farthest from the tube. Of course, the passage of the gas through the pipe or each passage must of course pass through the hemispherical part or enter the pipe on it, but the former is preferred. 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 this seat part is better, so that the shape of the hemisphere has a flat lower surface, and this -The device, as explained in detail later, has been found to be very advantageous for the device about the passage of the gas flow through the tube. Β ηίΐ provides a means to move in an oblique direction than when the tube is fixed. Few are easy to break. In this way, without a hemispherical seat, Guan Yu can still be slightly = pipeline to be closed, and when recording or dancing, it can be made so that it can not perform its function as required at a critical time.

With any necessary pipelines, the quasi-predictable correction can be corrected, and the silk material can be matched with the seat device. Adjustment. On the other hand, therefore, the present invention can provide a frangible tube having at least one gas through which a check passage can pass, one end of the tube having a cup-shaped shape, such as a substantially ball-shaped seat portion , So that it can be fitted with the smelting metal _ barrel outlet _ or its four pairs of quasi-qing. The fragile tube is preferably made of ceramic material * The ceramic material can withstand the temperature of molten steel, It is easy to break 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 single spherical protruding portion can be for example molded or from a larger diameter Take control of the mechanism. Several small straights: pumping gas The advantage of the channel device is that when the valve is opened, the gas pipe ruptures, and the next section remains fixed in the movable plate of the valve. If the molten gate is drained, the sliding gate valve must be closed. 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 smaller holes allow the gas to pass through while borrowing the melt The solidification prevents it from passing, and thereby prevents its own passage. As long as the tube part passing through the valve is broken when the valve is opened, the entire 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 on the top of the fragile tube, or vice versa, or pressed to fit between the two.

By; there is a considerable amount of the liquid pipe 5a extending into the gas pipe ^ (measured from the bottom to the rising nozzle about three quarters of the height and it means that good results can be obtained), the gas pressure is just right to be removed. Introduce below obstacles. In addition, the sand of '大部 # will be left in the nozzle, so it can prevent the melt from pushing down the nozzle to cause the risk of solidification and blocking the liquid drain. And the remaining sand will produce a downward pressure, and there is a reduced risk of leakage. However, if necessary, an appropriate collar can be positioned at the bottom of the opening 10 in the plate 9, surrounding the tube 13 and sealed between the plate 9 and the movable plate 11. The gasket should be a compressible, non-porous, high-temperature resistant material, such as a ceramic fiber material covered with a mica layer. Therefore, a gas pressure system will not affect the Thai dynamic units (not shown in the figure) for opening the valve, such as hydraulic piston and cylinder units, so the movable lower shell part 8 can be moved to the right as shown in Figure 1 Open the nozzle hole. In this regard, the gas tube 13 engages the inner wall of the inner nozzle 5 and is cut at the front face of the lower edge of the latter. This position is shown in Figure 3. However, in fact, the gas 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 insertion portion of the gas tube 13 above the valve plate M may be opened to the position shown in FIG. 3. The continuous opening movement can open the cover of the draining tank, so that the dazzling liquid can flow out through the inner nozzle 5, through the flow opening 10 and then out of the lower valve plate outlet tank 12. Here, the cut-off portion of the gas pipe 13 is performed separately along this. The remaining part of the gas tube 13 in the lower shell portion 8 can be removed by releasing the adhesive fixing the joint member μ 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.

Description of the invention (7) The curved surface of the truncated hemispherical seat part i3a at its lower end is formed so that it can be fitted with a similar curved recess in the joint 14. With the seat part 13a and The curvature of the fitting surface between the joints 14 can accommodate any misalignment of the necessary bend direction of the tube so that the tube will not be damaged during insertion through the valve and during insertion into the outlet. As shown, the tube 13 has four axial gas passages extending from the top of the tube and rising out of the flat end surface 13c of the truncated hemispherical seat. As shown 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 of each hole 13b being blocked during the formation of the hemispherical portion is smaller than that which appears in the Zanqu area.-For example only, the diameter of the tube 13 and the end surface 13 may be about 8 mm, and The radius of the hemisphere can also be about 8 mm, and the diameter of each axial channel is about 2 mm. The length can exceed 200 mm, for example from 35 to 700 mm in length. In Figure 7, the "floating mandrel" connection between the lower end of the frangible tube and the lower side of the valve housing is shown. In this specific example, the cup-shaped wall 13a of the frangible tube I3 is seated in a complementary recess in the upper surface of the floating mandrel. The mandrel 20 is installed on the inside of the ring. The shell 2 is inside, while the shell 21 is It is clamped to the lower side of the valve member 8 by a base 22. A sealed o-ring 21a seals the shell 21 and the base 22. The annular recess is bounded between the mandrel 20 and the inner wall of the shell 21. The lower end is initially fixed to the underside of the base 22 by a gasket 22a. The gas can be connected to the pipe through a passage 25 from the gas source (not shown in the figure) into the annular recess 23 and the center 20. The tube 24 of the base t3a of 13 was introduced into the tube 13. n ^ — 1 m (I ml nn 0 (please read the note ^ ′ on the back and then Jr. this page) -1 — line-i Ministry of Economic Affairs Printed by the Bureau of Standards and Employee Consumer Cooperatives • mi ......... 1-; i I-i 1 · — — — —-________ ) ~ " 3126J8 Α7 Β7 V. Description of the invention (The plug 26 can close the lower end of the shell M and is sealed by the O-ring and the inner wall of the shell. The plug 26 has an upper annular shoulder 28, which is The upper periphery of 28 can receive a stepped retaining ring 29. The lower portion of mandrel 20 has a depending central boss and annular shoulder 31. Shoulder 31 is supported on the upper surface of retaining ring 29, and boss 30 is a series Protruding from the retaining ring to leave an annular recess between itself and the ring. The centrally extending cavity of the boss 30 that extends vertically can also receive the legs of the connector or box base 32. The horizontal sample of "Ding Ding" is supported on the upper surface 26a_h of the plug 26 between its shoulders but separated from each shoulder. This device allows easy assembly of the tube 13 and the arrangement of its seats in the housing 21. The annular recesses 23 and 29A may allow the oblique one side of the mandrel 20 to be " floating " and cater to the vertical misalignment of the tube 13. This: the correction feature of the cup-shaped end of the tube 13 can provide the most advantageous device (please read the precautions on the back first and then h.
