Description

Technical Field

[0001] This utility model is a water-cooled intermediate tank cover plate, belonging to the field of metallurgical continuous casting casting parts. Background Technology

[0002] Currently, in the continuous casting process of the metallurgical industry both at home and abroad, intermediate tank covers are indispensable for the casting process.

[0003] The tundish cover serves two purposes: first, it is used during the baking of the tundish to ensure that the flame can reach the refractory material at the bottom and sides of the ladle, baking the refractory material at a temperature of approximately 1100 ℃, thus ensuring the tundish is properly heated; second, it maintains the temperature of the molten steel during the casting process, reducing heat loss and thus serving as a heat preservation function.

[0004] Because the tundish cover is relatively close to the surface of the molten steel in the tundish, generally within the range of 200 to 300 mm, the radiant and convective heat transfer of the molten steel will cause thermal shock to the tundish cover, which will then damage the tundish cover. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water-cooled intermediate tank cover plate.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A water-cooled intermediate tank cover plate includes an intermediate tank cover plate body and a water-cooling device. The intermediate tank cover plate body includes a rectangular frame with a plurality of hooks inside. The rectangular frame is filled with refractory material. The water-cooling device includes a serpentine coil at the bottom of the water-cooling device. The two ends of the serpentine coil are respectively provided with a water inlet and a water outlet. The rectangular frame and the serpentine coil are connected and fixed by a connecting mechanism.

[0008] Furthermore, the connecting mechanism includes a plug-in groove formed at the bottom of the rectangular frame and a slot and a receiving groove formed on the outer surfaces of both sides of the rectangular frame. The slot and the receiving groove are connected to both sides of the plug-in groove. A plug-in plate is inserted into the plug-in groove and is connected and fixed to the serpentine coil. A snap-fit ​​member is passed through the slot, and the snap-fit ​​end of the snap-fit ​​member passes through the plug-in plate into the receiving groove.

[0009] Furthermore, a locking member is engaged inside the receiving groove. Both ends of the locking member have grooves. The engaging end of the locking member passes through the grooves. A first engaging groove and a second engaging groove are respectively formed on both sides of the engaging end. A first limiting plate and a second limiting plate are slidably fitted on the engaging end. A through hole is formed on both the first limiting plate and the second limiting plate. The through holes of the first limiting plate and the second limiting plate are engaged and fixed with the first engaging groove and the second engaging groove, respectively.

[0010] Furthermore, both the first limiting plate and the second limiting plate are provided with bolt holes, and locking bolts are threaded into the bolt holes. The end thread of the locking bolt passes through the locking member and is threadedly fixed to the receiving groove.

[0011] Furthermore, the rectangular frame is welded from steel plates, and the sides of the rectangular frame are provided with several lifting lugs.

[0012] Furthermore, the plug-in plate has through holes that mate with the snap-fit ​​component.

[0013] Furthermore, the hook is formed by bending round steel.

[0014] Furthermore, the serpentine coil is a water ring pipe welded from steel pipes.

[0015] The beneficial effects of this utility model are:

[0016] Through the design of the water cooling device, when in use, the water inlet of the water cooling device is connected to an external water source. As the water flows along the serpentine coil, it carries away the heat from the body of the intermediate tank cover through heat exchange, and the heated water flows out from the outlet.

[0017] The design of the lifting lugs facilitates the hoisting of the water-cooling device.

[0018] Through the design of the connecting mechanism, during the installation of the serpentine coil, the plug-in plate on the side of the serpentine coil is first installed in the plug-in slot. Then, the locking member is plugged in and installed in the receiving slot. Next, the snap-fit ​​member is inserted and snapped into the snap-fit ​​slot. The snap-fit ​​end of the snap-fit ​​member passes through the snap-fit ​​slot, the plug-in slot, and the receiving slot in sequence, extending into the groove on the inner locking member. Then, the limiting plate is first placed on the snap-fit ​​end of the snap-fit ​​member in the groove. Then, the first limiting plate is moved laterally so that the through hole on the first limiting plate is snapped and fixed together with the first docking slot on the snap-fit ​​member. Then, the above operation is repeated to snap the second limiting plate into the second docking slot on the snap-fit ​​member. At this time, the first limiting plate and the second limiting plate lock the snap-fit ​​member and the locking member into a whole. Finally, the locking bolt passes through the bolt holes on the second limiting plate, the first limiting plate, and the locking member in sequence and is connected and fixed with the bolt holes on the receiving slot.

The rectangular frame 3 and the serpentine coil 9 are connected and fixed by a connecting mechanism. The water inlet 7 on the water-cooling device 2 is connected to an external water source. As the water flows along the serpentine coil 9, it carries away the heat on the intermediate tank cover plate body 1 through heat exchange. The heated water flows out from the water outlet 8.

[0032] See Figures 2-9The connecting mechanism includes an insertion slot 11 at the bottom of the rectangular frame 3 and slots 12 and receiving slots 13 on the outer surfaces of both sides of the rectangular frame 3. Both slots 12 and receiving slots 13 communicate with the two sides of the insertion slot 11. An insertion plate 10 is inserted into the insertion slot 11 and is fixedly connected to the serpentine coil 9. A snap-fit ​​member 14 passes through the slot 12, with its snap-fit ​​end passing through the insertion plate 10 into the receiving slot 13. The insertion plate 10 has a through hole that mates with the snap-fit ​​member 14. The receiving slot 13 contains... A locking member 17 is engaged, with grooves 18 at both ends. The engaging end of the engaging member 14 passes through the grooves 18. A first engaging groove 15 and a second engaging groove 16 are respectively formed on both sides of the engaging end. A first limiting plate 19 and a second limiting plate 20 are slidably fitted onto the engaging end. A through hole 21 is formed on both the first limiting plate 19 and the second limiting plate 20.

A water-cooling device 2 is added between the intermediate tank cover plate body 1 and the radiant heat of the high-temperature molten steel. The inlet 7 of the water-cooling device 2 is connected to an external water source. As the water flows along the serpentine coil 9, it carries away the heat from the intermediate tank cover plate body 1 through heat exchange. The heated water flows out from the outlet 8, thereby improving the service life of the intermediate tank cover plate body 1. After prolonged use at high temperatures, the serpentine coil 9 experiences significant wear and needs to be replaced to maintain its heat dissipation performance. At this point, the locking screw...
