Description

Technical Field

[0001] This utility model relates to the field of steelmaking slag basin technology, specifically, to a steelmaking slag basin. Background Technology

[0002] High-temperature melts such as molten steel and molten iron cannot be cast into blocks or returned to the furnace due to low temperature or other reasons, and are therefore dumped into slag basins. Due to the different operational needs of steel companies, high-temperature melts such as molten steel and molten iron need to be cut a second time after solidification in the slag basin to meet production needs.

[0003] The existing publicly available technology, application number CN202321146649.5, describes a steelmaking slag basin that is used in conjunction with a solidification box via a plug-in mechanism. The solidification box, with a corresponding size grid, can be installed into the installation slot according to the required block size. This allows for the replacement of the solidification box with the corresponding specification without replacing the slag basin body, reducing the cost of using the slag basin and providing convenience for processing personnel.

[0004] However, the aforementioned patent still has certain drawbacks in its use: although it can restrict the operation of different blocks by changing different types of solidification boxes, the internal structure of the solidification box is also fixed and cannot be adjusted. It is necessary to frequently change solidification boxes with different internal structures, which increases the overall consumption, leads to higher usage costs, and causes inconvenience to processing personnel. At the same time, the temperature of the melt put into the steelmaking slag basin is high, and this heat will diffuse into the air, which will not only cause burns to personnel, but also cause heat loss. It is not energy-saving and environmentally friendly, and the overall usage effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] (a) Technical problems to be solved

[0008] (II) Technical Solution

[0009] To achieve the advantages of waste heat utilization, internal cavity adjustment, and diverse size types, the specific technical solution adopted by this utility model is as follows:

[0010] A steelmaking slag basin includes a slag basin body and an inner basin body. The inner basin body is installed in the middle of the slag basin body. A heating chamber is provided between the inner basin body and the slag basin body. Several sets of slots are opened at the top of the inner basin body. Long partitions are snapped between each pair of slots. Several sets of positioning holes are opened at the top of one side surface of the long partitions and at the top of both sides of the inner basin body. Several sets of butt joints are uniformly welded at the top of the other side surface of the long partitions. Several sets of short partitions are inserted between each pair of long partitions and between the long partitions and the inner basin body. The short partitions have the same structure as the long partitions, but their size is half that of the long partitions. The inner basin body has a receiving cavity inside.

[0011] Furthermore, several sets of heat-conducting fins are evenly installed around the outer surface of the inner basin, located inside the heating cavity.

[0012] Furthermore, several sets of circulating water pipes are staggered and installed on one side surface of the slag basin body.

[0013] Furthermore, the main body of the slag basin is symmetrically welded with bearing plates on both sides. A limiting groove is formed at the top of the bearing plate. A sliding strip is slidably connected inside the limiting groove. A limiting plate and an anti-detachment plate are respectively provided at one end of the sliding strip and one end of the limiting groove. A sealing cover is welded at the top of the sliding strip.

[0014] Furthermore, a gas collection hood is installed at the top of the sealing cover, and an exhaust pipe is installed at the top of one side surface of the gas collection hood. The exhaust pipe is connected to an external waste heat utilization device.

[0015] Furthermore, several sets of moving wheels are evenly installed around the bottom of the slag basin body.

Several sets of positioning holes 6 are opened at the top of one side surface of the long partitions 8 and at the top of both sides surface of the inner basin 3. Several sets of butt joints 9 are uniformly welded at the top of the other side surface of the long partitions 8. Several sets of short partitions 11 are inserted between each pair of long partitions 8 and between the long partitions 8 and the inner basin 3. The short partitions 11 have the same structure as the long partitions 8, but their size is half that of the long partitions 8. The inner basin 3 has a receiving cavity 7 inside.

[0032] In one embodiment, several sets of heat-conducting fins 2 are uniformly installed around the outer surface of the inner basin 3, located inside the heating cavity 17. The heat-conducting fins 2 are designed to increase the heat-conducting area and facilitate better heat transfer.

[0033] In one embodiment, several sets of circulating water pipes 4 are installed alternately on one side surface of the slag basin body 1. The purpose of the circulating water pipes 4 is to introduce water into the heating chamber 17, and then utilize the waste heat through the heating of the water.

[0034] In one embodiment, a bearing plate 19 is symmetrically welded to both sides of the slag basin body 1. A limiting groove 5 is formed at the top of the bearing plate 19. A sliding strip 15 is slidably connected inside the limiting groove 5.

[0035] In one embodiment, a gas collecting hood 13 is installed at the top of the sealing cover 12, and an exhaust pipe 14 is installed at the top of one side surface of the gas collecting hood 13. The exhaust pipe 14 is connected to an external waste heat utilization device, such as a radiator or a boiler, without specific limitations.
