OBJECTS OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to a slab cooler for a blast furnace, which is configured to absorb 5 stresses caused by thermal expansion between the slat body and the iron sheet, in particular a The stress acting on the welded portion between the water supply and drainage take-out pipe and the slat body can be minimized and can be used for a long time. [Just 4 standard; j Background of the invention 10 15 In the current blast furnace operation, a slat cooler (hereinafter also referred to as a slat) is widely used as a means for cooling the fireplace. In recent years, in the operation of blast furnaces, as the output volume increases and the output efficiency increases, compared with the past, the heat load of the blast furnace body is increased, and it is increasingly required to cool the plate of the furnace body more effectively. Strip cold device. In this development, it has recently been developed that the cast iron slats are more excellent than the known cast iron slats, or steel slat coolers are becoming more suitable. l When the slats made of copper or noodle alloy are used in the blast furnace, the new problems of the white cast iron slats are becoming more and more obvious. That is to say, "the conventional cast iron plate (4) is a structure in which the cooling pipe is placed in the model plate of the slat body in advance, and then the cooling pipe and the slat body are integrally formed, so that there is no slat until the outer side of the iron sheet. The structure of the joint between the main body and the tube is welded to the following structure and the steel plate or the slab of the same alloy is cooled, that is, after the cooling tube is formed in the slat body, Because of the need for 20 200920851 body water supply and drainage port and water supply and drainage pipe, there is a fusion joint near the slat body. The slab joint near the slat body in the copper or copper alloy slat cooler is in the blast furnace operation. When the inside of the 5 furnaces of the slat main body exposed to high temperature is in contact with the displacement caused by the difference in thermal expansion between the iron side of the slat main body for cooling and releasing heat, stress is concentrated. Fatigue cracking at this part causes the life of the slat cooler to be shortened. In the general slat installation, as shown in Fig. 6, the slats are attached by the mounting bolts 8 1〇 and the iron nut 9 The body 1 is fixed to The iron sheet 6 is used to disperse the load, so that the load of the slat body 1 does not directly act on the water supply and drainage take-out tube 2. The water supply and drainage take-out tube 2 of the slab cooler made of copper or copper alloy is welded to the board as shown in Fig. 3 The water supply and drain port of the strip body 1. The opening portion of the iron sheet 6 for penetrating the water supply and drain pipe 2 is sealed by welding the water supply and drainage pipe 15 and the iron sheet 6 through the sealing plate 5, and is sealed in the furnace of the blast furnace. The gas leaks to the outside of the iron sheet. The conventional slats shown in Figures 3 and 6 are in the blast furnace operation due to the difference in thermal expansion between the inside of the slat body and the side of the slab, and thus the iron side of the slat body The displacement caused by the difference in thermal expansion between the iron sheets causes a change in stress 2,. At this time, the longitudinal or mounting bolt 8 can share the load of the lath body, and the stress fluctuation due to the difference in thermal expansion cannot be absorbed. Therefore, copper or copper alloy In the slat cooler, the stress fluctuation caused by the difference in thermal expansion during the operation of the blast furnace is particularly concentrated as stress. P is the dazzling between the water supply and drainage pipe near the iron sheet and the slat body. In addition, the sealing plate 5 that connects the water supply and drainage pipe 2 and the iron sheet 6 is likely to be deformed when the slat body and the iron sheet are displaced due to a difference in thermal expansion, and Although it has the effect of reducing the stress of the welded joint between the iron and the water supply and the drainage pipe in the vicinity of the slat body, the sealing plate 5 itself is still damaged by the deformation caused by the repeated stress, which may cause gas leakage in the furnace. In the above-mentioned technical problem, there has been a method of joining a water supply and drainage pipe and a metal sheet through a telescopic tube having a retractability (for example, Japanese Patent Laid-Open Publication No. SHO 52-85). As shown in Fig. 4, the telescopic tube 7 is disposed to cover the water supply and drainage take-out tube 2, and the water supply and drainage take-out tube 2 and the iron sheet 6 are welded through the telescopic tube. At this time, the sealing plate 5 welded to the end of the bellows 7 and the water supply and drainage take-out battalion 2 is sealed, so that the gas in the blast furnace furnace is not leaked outside the circumference 15 . According to the method of the present invention, when the heat transfer is caused by the difference in thermal expansion between the slat body and the iron sheet, the tension can be absorbed by the expansion tube 7 in the direction of thermal expansion or thermal contraction, thereby obtaining a stress-stable difference. The resulting force of 0 causes the effect of the fatigue damage in the seal plate 5 between the iron and the water supply and drainage pipe near the slat body. As shown in Fig. 4, the 'receiving' telescopic officer 7 is easy to make a wrinkle structure, etc., and the opposite side of the telescopic structure, and the extension of the telescopic tube 7 due to years of use It is fast, and it is easy to cause fatigue damage, and there is a problem on the surface of durability. ^ ' 200920851 Therefore, it is necessary to replace the telescopic tube 7 regularly so as to avoid the occurrence of perforations or cracks in the telescopic tube 7, and let the gas in the furnace leak to the outside, or simply repair the telescopic hole 7 to have a through hole or crack. The part, therefore, has the problem of requiring a lot of labor 'again' because of the shutdown of the blast furnace, etc., there is a problem of reduced productivity. 5 Further, when the slat load acts on the welded portion between the slat main body and the water supply and drain pipe due to the deformation of the slat mounting bolt, etc., the welded portion between the slat main body and the water supply and drainage take-out pipe may be fatigue-damaged, and There is leakage of cooling water, which has the danger of causing water in the furnace. Further, as a method of attaching a conventional cast iron slat to a metal sheet, it is known that the slats are quickly replaced by omitting the mounting bolt 8 and the nut 9 of the slat main body. As shown in Fig. 5 and Fig. 7, the shy tube 3 is placed on the slat body to cover the water supply and drainage power take-off tube 2, and further, the comb box 4 is placed around the iron sheet opening portion to cover The protective tube 3, and between the water supply and drainage take-out tube 2 and the protective tube 3, and between the comb-shaped box 4 and the protective tube 3 are fixed by the filler 10 and the fixed block 11, respectively (refer to Japanese Patent Laid-Open Publication No. JP-A-8: 225813). According to this method, the water supply and drainage take-out pipe 2 and the protective pipe 3' can be fixed by the filler 10 or the like to increase the rigidity of the water supply and drainage take-out pipe 2, and the protective pipe 3 and the comb case 4 can be fixed by the filler 10 or the like. The mounting bolt 8 and the nut 9 of the slat body 1 can be omitted by supporting the load of the slat body 20 as shown in Fig. 7. The method can also be applied to longitudinal or copper or copper alloy strips. However, in this method, since the water supply and drainage take-out pipe 2, the protective pipe 3, and the comb-shaped case 4 are integrated, the displacement stress due to the difference in thermal expansion between the slat body 1 and the iron sheet 6 cannot be absorbed, and the plate The fuse between the strip body 1 and the water supply and drainage take-up tube 2 200920851 > _stress* in If%' makes the possibility of fatigue damage worse. For example, in recent years, the heat of the blast furnace I with the high-yield blast furnace operation has increased. The inside of the slab body and the iron side, and then the thermal expansion between the plate L and the iron side of the body and the iron sheet. Therefore, the possibility of fatigue damage is improved in the fusion portion between the slat main body and the water supply and drainage take-out pipe, and further, the slats of the head can not be improved. The sufficient effect of the slat life is the status quo. 10 SUMMARY OF THE INVENTION In view of the state of the art described above, it is an object of the present invention to provide a slab slab cooling n which is capable of absorbing a blast furnace body associated with a high throughput blast furnace operation. The stress caused by the difference in thermal expansion between the slat body and the iron 15 caused by the increase in heat load, and the fusion between the slat body and the water supply and drainage officer, and the fatigue failure in the welded portion between the iron sheet and the water supply and drainage take-out portion It has a high reliability constructor that can be used for a long time. The present invention is directed to a technical subject, and the gist of the present invention is a slab cooler for a blast furnace, which is obtained by welding a water supply and drainage take-out pipe to a copper or copper 20 alloy slat body, and the slat body and the blast furnace The iron sheet is fixed by a plurality of steel mounting bolts, wherein the protection tube is welded to the slat body to cover the water supply and drainage unit; and the comb is provided on the outer surface of the opening formed on the iron sheet. a shape box for covering the protection tube; one of the end portions of the side plates of the comb box is welded to the iron sheet; and the side 9 200920851 = the side of the system, the board is the blast furnace according to the invention of the foregoing protection tube With a slat cooler, when using the cooling performance «LA m U Ludi-steel Q-gold slat cooler, 5 is accompanied by a high-yield blast furnace operation, which is made by the ancient secret steep ', and ', and The difference between the heat of the slat body and the iron (4) caused by the increase in the thermal load of the furnace body can be suppressed by the slat body and the water supply and drainage, and the welded joint between the official and the iron and the drainage pipe.

In the slab cooler for blast furnace according to the present invention, as shown in Figs. 1 and 2, the water supply and drainage take-out pipe 2 is welded to a copper or copper alloy slat body sill, and the slat body 1 and the blast furnace iron 6 are It is fixed by a plurality of steel mounting bolts 8. By making the slat body made of copper or copper alloy, the thermal conductivity can be improved compared with the conventional 10 cast iron slat body, and the cooling water can be circulated in the cooling water pipe in the slat body. The heat from the inside of the furnace of the slat body is eliminated. Further, the load of the slat body 1 is supported by a plurality of steel mounting bolts 8. Although the steel mounting bolt 8 can share the weight of the slat body, it does not absorb the stress variation caused by the difference between the slat body i and the iron sheet 6. Therefore, in the present invention, as shown in Figs. 1 and 2, the slab cooler for a blast furnace has a structure in which the protective tube 3 (4) is placed on the slat body , to cover ’. Draining s 2' and forming a metal box 2 on the outer periphery of the opening portion on the iron sheet, a comb-shaped box 4 is provided to cover the protective tube 3, and the iron sheet 6 is dazzled in the side plate port p of the comb-shaped phase 4 - The other of the side plate end portions is welded to the outer circumference of the water supply and drainage pipe 2 via the sealing plate 5. In the slat structure, since the protective tube 3 is fused to the slat cut 1 by means of covering the water supply and drainage take-out tube 2, the stress needle portion, that is, the slats 200920851 body 1 and the water supply and drainage port and the water supply and drainage take-out tube 2 The cross-sectional area in the vicinity of the welded portion is enlarged, and the weight of the portion can be shared by the protective tube. When the displacement due to the difference in thermal expansion occurs, the stress on the welded portion of the water supply and drainage take-out tube 2 can be reduced. 5 If the thickness of the tube of the protective tube is less than 5 mm, sufficient strength cannot be obtained, and if it exceeds 7 mm, the gap between the tube and the water supply and drainage tube becomes narrow and it is not easy to be welded, so that it is based on the reason that it can have sufficient strength and is easy to be welded. It should be 5mm 7mm. Further, the material of the protective tube is made of carbon steel for high-temperature piping because it has strength and can be welded even when exposed to a high temperature. Further, in the opening formed in the iron sheet, the comb case 4 is disposed so as to cover the protective tube 3, and the water supply and drainage take-out tube 2 and the protective tube 3 are not directly bonded to the iron sheet, and may be thermally expanded. The displacement state is performed, and the water supply and drainage removal pipe 2 and the protection pipe 3 are welded to the iron sheet 6 via the comb case 4, and when the displacement due to the difference in thermal expansion occurs, the comb case 4 is generated in the displacement direction 15. The opening is opened, whereby the stress of the welded portion of the water supply and drainage take-out pipe 2 can be reduced. Furthermore, since one of the end portions of the side plates of the comb box 4 is in contact with the iron surface of the outer periphery of the opening portion, and the other of the side plate end portions of the comb box 4 and the outer peripheral surface of the protective tube 3 are separated by a sealing plate 5, the welding is performed, so that the gas system in the blast furnace is sealed by the side plates of the comb box 4 and the sealing plate 5 to prevent leakage to the outside of the iron 20 skin. Further, in the opening portion of the aforementioned iron sheet 6, when the displacement due to the difference in thermal expansion during the operation of the blast furnace occurs, the longitudinal or the water supply and drainage take-out tube 2 and the protective tube 3 are somewhat deformed, but the free contact with the iron sheet is free. The state of the shift 'cause' should have a sufficiently large opening diameter compared to the outer diameter of the protective tube 3. 12 200920851 In addition, 'the side plate and the sealing plate 5 constituting the comb-shaped box 4 are preferably metal plates such as steel plates having a thin plate thickness, and when there is a displacement caused by a difference in thermal expansion in the operation of the blast furnace, It can be shrunk in the direction of displacement. If the length of the side plate is less than 40 mm, the length is too short to sufficiently absorb the displacement caused by the difference in thermal expansion of 5, but if it exceeds 120 mm, it is too long and interferes with the surrounding equipment. For the above reasons, the length of the side plate is preferably 40 mm. 120mm. If the thickness of the side plate is less than 8 mm, it is too thin to be easily welded. When it exceeds 10 mm, although it is not easily deformed, it cannot absorb the difference in thermal expansion. Therefore, the side plate is maintained by sufficient strength and easy to be welded. The thickness should be 8mm~1 〇mm 〇 and the thickness of the sealing plate 5 is too thin to be too thin when it is less than 5mm. When it exceeds 7mm, it is not easy to deform but cannot absorb the difference in thermal expansion. Therefore, it is sufficient to maintain sufficient The thickness of the sealing plate 5 15 is preferably 5 mm to 7 mm for reasons of strength and ease of welding. Further, the material of the side plate and the sealing plate is preferably a normal carbon steel because it has sufficient strength and is easy to be spliced. Further, the inner space of the comb box and the sealing plate should not be filled with the filling castings and the refractory, etc., so that the comb box and the sealing plate are easily deformed and can absorb the difference in thermal expansion. Further, the method for producing the copper or copper alloy strip according to the present invention is not particularly limited, but it can be generally produced as follows. First, in the inner side of the furnace ~ the outside of the furnace, each of the wooden molds having the same shape as the slats is formed, and the wooden mold is placed on each mold corresponding to the inner side of the slats and the outside of the furnace 13 200920851. Then pour the sand. Third, the solid material removes the wooden dragon and calls it a sand mold. The hydrophobic channel system and the sand of the S3 sand are made and placed at a fixed position of the sand mold. Knife Fourth, let the inner side of the furnace and the sand mold on the outside of the furnace be combined up and down, and the joint of copper or copper alloy is injected into the main port. Fifth, remove the sand mold after solidification, ^ the same as the copper strip body (4), the plug is connected to the sand hole. The _ = button is connected to the water supply and drainage port, and the lining of the lining (4) is given to the water supply and drainage. There is also a manufacturing method as follows, that is, a rolled copper plate or a dry copper alloy plate which is the same as the slats. The water channel is discharged, and the hole which is not required is embedded in the same material as the slat body and melted, and the protective tube is welded to cover the water supply and drainage tube. EXAMPLES Hereinafter, examples of the invention will be described by way of illustration. As shown in Fig. i and Fig. 15 and Fig. 2, a copper slat cooler for protecting f3 and the comb box 4 is disposed around the water supply and drainage take-out pipe 2 which is fused to the copper slat body 1 of the present invention, and The four places in the slat body are fixed to the iron of the blast furnace body by copper bolts and nuts. Further, in order to confirm the effectiveness of the copper slats of the present invention, a conventional steel 2 slab slat cooler is used to weld the water supply and drainage take-up tube 2 to the conventional copper slat body 1 by a sealing plate 5 The slat body and the water supply and drainage take-out pipe are connected to the iron sheet and are similarly mounted on the iron of the blast furnace body and simulate the cooling of the hair-like copper slats and the conventional copper slat cooler for blast furnace operation. The welding of the two joints and the damage of the sealing plate 5 are 200920851. Furthermore, the steel slats of the present invention. Ordinary carbon steel with a degree of 9 mm, sealed: in the crucible, the comb box is made of thick steel. In the reverse, a normal carbon having a thickness of 6 mm was used. 5 10 15 20 According to the simulation results, no damage was found in the reverse strip cooler between the noodle body 1 of the present invention and the water supply and drainage take-out tube 2. "The joint and the damage in the sealing plate 5, on the other hand, the conventional copper slat A', the joint between the mouth draining pipe 2, and the "part", the slat body 1 and the feeding portion, It is possible to cause damage to the joint take-out pipe and the seal plate between the iron sheets of the stress-sealing plate 5, and it is apparent that the usability of the water supply and drainage industry is high.
