Description

Technical Field

[0001] This utility model belongs to the field of continuous casting crystallizer technology, and in particular relates to a water cooling system for continuous casting crystallizer. Background Technology

[0002] A crystallizer is a continuous steel casting device that receives molten steel poured from an intermediate ladle and solidifies it into a solid billet shell according to a specified cross-sectional shape. Therefore, cooling is required when the crystallizer is working, and water cooling is more effective. Thus, a water cooling structure for the crystallizer is used.

[0003] Existing continuous casting crystallizers typically use a single water-cooling pipe for cooling. While this method can achieve cooling, the water cooling efficiency is low. Furthermore, the water temperature gradually increases from top to bottom, resulting in uneven cooling. This makes it easy for cracks to appear after the material solidifies, greatly reducing the applicability of water cooling systems for continuous casting crystallizers. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water cooling system for continuous casting crystallizer, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a water-cooling system for a continuous casting crystallizer, comprising a crystallizer chamber and a water tank body disposed on one side of the crystallizer chamber, and further comprising:

[0007] The refrigeration component is fixed on one side of the water tank. A connecting pump is provided on the upper end of the refrigeration component. A connecting pipe is fixed at the tail end of the connecting pump, and the other end of the connecting pipe extends into the crystallizer chamber.

[0008] A heat-conducting cylinder is installed inside the crystallizer chamber, and a cooling chamber is provided between the crystallizer chamber and the heat-conducting cylinder. A cooling mechanism is installed inside the cooling chamber to cool the inside of the crystallizer chamber.

[0009] The sealing mechanism is located on the lower end face of the crystallizer chamber and is used to seal the lower end face of the crystallizer chamber.

[0010] Furthermore, a scale is provided in the center of one side of the water tank, and a protective cover is provided on the upper surface of the water tank, with the center of the protective cover having a hollow structure.

[0011] Furthermore, the cooling mechanism includes a spiral tube, a branch pipe, and a branch guide device. The spiral tube is spirally arranged inside the cooling chamber. The branch pipe is connected to the tail end of the spiral tube. The branch guide device is fixed to the tail end of the branch pipe, and one end of the branch guide device is connected to the water tank body.

[0012] Furthermore, the inner wall of the spiral tube is uniformly provided with spray guide ends, and the inner wall of the spray guide ends is in contact with the outer surface of the heat conduction cylinder.

[0013] Furthermore, a flow pipe is connected to one side of the lower end face of the cooling cavity, and the other end of the flow pipe is connected to the guide bracket.

[0014] Furthermore, the sealing mechanism includes a servo motor, a sealing baffle, and a cover plate. The servo motor is located on one side of the lower end face of the crystallizer chamber, the sealing baffle is fixed to the output end of the servo motor, and the other end of the sealing baffle is tightly fitted to the lower end face of the crystallizer chamber. The cover plate is snapped onto the upper end face of the crystallizer chamber.

[0015] This utility model has the following beneficial effects:

[0016] This invention utilizes a refrigeration assembly to cool the water tank. A connecting pump guides water through a connecting conduit into a spiral tube within the crystallizer chamber. This spiral tube, positioned outside a heat-conducting cylinder, cools the inside of the cylinder. Simultaneously, a spray nozzle inside the spiral tube sprays water into the heat-conducting cylinder, further dissipating heat. The ends of the spiral tube and the flow pipe are then connected to a guide frame, guiding water back into the water tank for circulating cooling, ensuring effective cooling of the subsequent crystallizer chamber.

The scale 4 is transparent and has graduations on its surface, which allows the water volume in the water tank 2 to be controlled. At the same time, the protective cover 5 can protect the connecting pump 6, which not only facilitates the subsequent heat dissipation of the connecting pump 6, but also facilitates the subsequent inspection and maintenance of the connecting pump 6.

[0027] A heat-conducting cylinder 8 is installed inside the crystallizer chamber 1, and a cooling chamber 9 is provided between the crystallizer chamber 1 and the heat-conducting cylinder 8. A cooling mechanism is installed inside the cooling chamber 9 to cool the crystallizer chamber 1. The cooling mechanism includes a spiral tube 10, a branch conduit 12, and a guide bracket 13.

One end of the guide bracket 13 is connected to the water tank body 2. The spiral tube 10 can be connected to the connecting conduit 7. When the spiral tube 10 is fitted onto the outer surface of the heat-conducting cylinder 8, the heat can be quickly conducted due to the metal material of the heat-conducting cylinder 8. Then, the branch conduit 12 and the guide bracket 13 can guide and recover water for subsequent processing. The inner wall of the spiral tube 10 is uniformly provided with spray guide heads 11, and the inner wall of the spray guide head 11 is in contact with the outer surface of the heat conduction cylinder 8. Through the multiple sets of spray guide heads 11, water can be sprayed into the heat conduction cylinder 8, thereby further dissipating heat into the heat conduction cylinder 8 and ensuring the cooling effect of the heat conduction cylinder 8. A flow pipe 14 is connected to one side of the lower end face of the cooling cavity 9, and the other end of the flow pipe 14 is connected to the guide bracket 13. The cooling water sprayed through the spray guide head 11 can enter the cooling cavity 9, and the flow pipe 14 can guide the water in the cooling cavity 9 to the guide bracket 13, thereby enabling the water in the guide pipe 12 and the cooling cavity 9 to be recycled. The other end of the guide bracket 13 can also be connected to a pump, thereby guiding the water into the water tank 2, enabling the water to be recycled.

[0028] A sealing mechanism is installed on the lower end face of the crystallizer chamber 1 to seal the lower end face of the crystallizer chamber 1. The sealing mechanism includes a servo motor 15, a sealing baffle 16, and a cover plate 17. The servo motor 15 is installed on one side of the lower end face of the crystallizer chamber 1. The sealing baffle 16 is fixed to the output end of the servo motor 15, and the other end of the sealing baffle 16 is tightly fitted to the lower end face of the crystallizer chamber 1. The cover plate 17 is snapped onto the upper end face of the crystallizer chamber 1. The servo motor 15 can drive the sealing baffle 16 to rotate. When the sealing baffle 16 rotates and cooperates with the cover plate 17, it can seal the crystallizer chamber 1 and solidify the molten steel entering the heat-conducting cylinder 8.
