Description

Technical Field

[0001] This utility model relates to the field of refining furnace cover technology, and in particular to a furnace cover that prevents cold steel from accumulating during steelmaking in a refining furnace. Background Technology

[0002] The furnace cover of a refining furnace is a device used to prevent slag from splashing during the steelmaking process. During steelmaking, the electrodes are energized for electrolysis and argon gas is blown from the bottom of the furnace, causing slag in the molten steel to splash upwards. By covering the top of the furnace, the furnace cover effectively prevents slag from splashing out of the furnace, ensuring operational safety and environmental cleanliness.

[0003] The furnace cover cooling device is achieved through a spirally wound water pipe structure. The water pipe is welded in a ring inside the furnace cover, circulating cooling water to reduce the temperature. Since the temperature above the molten steel is high, the cooling water pipe can effectively prevent the furnace cover from being damaged by high temperature, ensuring that the furnace cover is always kept within a safe temperature range and guaranteeing the safe operation of the equipment.

[0004] Because there are gaps between the cooling water pipes of the refining furnace cover, splashed steel slag will adhere to and accumulate in the gaps. Long-term steel slag adhesion will corrode the water pipes, causing water pipe damage and leakage, which in turn affects the cooling effect of the furnace cover and seriously endangers production safety. Therefore, a furnace cover that prevents cold steel accumulation during steelmaking in the refining furnace is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a furnace cover to prevent cold steel from accumulating during steelmaking in a refining furnace, aiming to improve the problem in the prior art where splashed steel slag adheres to and accumulates in the gaps of cooling water pipes, damaging the water pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A furnace cover for preventing cold steel accumulation during steelmaking in a refining furnace includes a base plate. A refining furnace, a water tank, and a water pump are mounted on the top of the base plate. A furnace cover is mounted on the top of the refining furnace. A cooling assembly is installed on the top of the furnace cover. A water pump is installed at each of the two connection ends of the water tank, and a quick-release assembly is installed at the connection end of each water pump. The cooling assembly includes a first connecting pipe and a second connecting pipe, both located on the top of the furnace cover.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a furnace cover for preventing cold steel accumulation during steelmaking in a refining furnace. The cover includes a base plate 1, a refining furnace 2, a water tank 3, and a water pump 4 on the top of the base plate 1. A furnace cover 5 is located on the top of the refining furnace 2, and a cooling assembly 6 is installed on the top of the furnace cover 5. A water pump 4 is installed at each of the two connecting ends of the water tank 3, and a quick-release assembly 7 is installed at the connecting end of the water pump 4. The cooling assembly 6 includes a first connecting pipe 8 and a second connecting pipe 9, which are located on the top of the furnace cover 5. Water enters and exits the furnace cover 5 through the first connecting pipe 8 and the second connecting pipe 9. An inlet pipe 10 and an outlet pipe 11 are fixedly connected to the ends of the first connecting pipe 8 and the second connecting pipe 9, respectively. The ends of the inlet pipe 10 and the outlet pipe 11 are located inside the quick-release assembly 7. Water enters the first connecting pipe 8 through the inlet pipe 10 and exits through the second connecting pipe 9 and the outlet pipe 11. The furnace cover 5 has a water-cooling tank 12 inside. Connecting pipe 8 and connecting pipe 9 are respectively set at both ends of the water-cooling tank 12. Water flows in the water-cooling tank 12, carrying away the heat inside the furnace cover 5. The bottom of the furnace cover 5 is provided with an anti-corrosion coating 24. The anti-corrosion coating 24 is made of silicon nitride material, which has good anti-corrosion performance and can withstand high temperature environment, effectively reducing the adhesion of steel slag.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The quick-release assembly 7 includes a connecting shell 14, which is fixedly connected to the connecting end of the water pump 4. A connecting plate 15 is fixedly connected to the side of the connecting shell 14 to protect the internal structure. A fixing plate 16 is fixedly connected inside the connecting shell 14. A spring telescopic rod 17 is installed on the side of the fixing plate 16, and a pressure plate 18 is fixedly connected to the side of the spring telescopic rod 17. The pressure generated by the cooperation of the fixing plate 16 and the spring telescopic rod 17 controls the movement of the pressure plate 18. Both the first connecting pipe 8 and the second connecting pipe 9 have locking blocks 13 fixedly connected to their sides. A sliding groove 19 is provided inside the connecting plate 15, and the locking blocks 13 are slidably connected inside the sliding groove 19, entering the connecting plate 15 from the sliding groove 19. A slot 20 is provided inside the connecting plate 15, and the locking blocks 13 and the slot 20 engage with each other. When the pressure plate 18 moves, it presses the locking blocks 13 into the slot 20, securely connecting the inlet pipe 10, the outlet pipe 11, and the water pump 4.

[0034] Reference Figure 1 , Figure 3 and Figure 4Protective sleeves 21 are fixedly connected to the sides of both connecting pipe 8 and connecting pipe 9. The protective sleeves 21 are located inside the connecting plate 15, fixing plate 16, and pressure plate 18, protecting the outer structure from contact with water and corrosion. A handle 22 is installed on the side of the water tank 3 to assist in moving the water tank 3. A limiting groove 23 is opened at the bottom of the furnace cover 5. The top of the refining furnace 2 is slidably connected to the inside of the limiting groove 23, which restricts the position of the furnace cover 5 at the top of the refining furnace 2.

[0035] Working principle: Water in water tank 3 is pumped into inlet pipe 10 by water pump 4, and then enters water cooling tank 12 inside furnace cover 5 through connecting pipe 1 8. Water is then pumped back into water tank 3 through connecting pipe 2 9 and outlet pipe 11 by water pump 4. The water is then cooled by carrying away heat from furnace cover 5 through water cooling tank 12. At the same time, the anti-corrosion coating 24 of silicon nitride material effectively reduces the adhesion of steel slag to the bottom of furnace cover 5 and prevents damage to cooling components 6.

[0036] The locking blocks 13 of the inlet pipe 10 and the outlet pipe 11 enter the connecting shell 14 through the slide groove 19 of the connecting plate 15. By rotating the locking blocks 13, the pressure generated by the cooperation of the fixing plate 16 and the spring telescopic rod 17 causes the pressure plate 18 to press the locking blocks 13 into the locking groove 20, thereby achieving a stable connection between the inlet pipe 10, the outlet pipe 11 and the water pump 4. When disassembly is required, the locking blocks 13 are moved inward to squeeze the pressure plate 18, and the locking blocks 13 are rotated to remove them from the slide groove 19, thereby achieving quick disassembly of the inlet pipe 10 and the outlet pipe 11 and improving the efficiency of inspection and maintenance.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
