Description

Technical Field

[0001] The present application relates to the technical field of crystallizers, and in particular to a crystallizer cooling system based on lowering the inlet water temperature. Background Art

[0002] The mold is a crucial component of the continuous casting machine. A bottomless copper tube mold with forced water cooling, it is known as the "heart" of the continuous casting machine. The mold receives molten steel from the tundish and solidifies it into a solid shell with a specified cross-sectional shape. It is the most critical component in the continuous casting machine, and its structure, material, and performance parameters play a decisive role in the quality of the cast strands and the production capacity of the casting machine.

[0003] When pouring begins, the head of the dummy rod is the movable inner bottom of the crystallizer. The molten steel injected into the crystallizer gradually condenses into a shell of a certain thickness and is continuously pulled out. At this time, the inner wall of the crystallizer is subjected to the combined effects of mechanical stress and thermal stress generated by the static pressure of the high-temperature molten steel and the friction force of the relative movement with the shell. Its working conditions are extremely harsh.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the inlet temperature of the cooling water is usually high, and the cooling efficiency is limited, which can easily lead to thermal cracks on the surface of the billet and internal pores, inclusions, etc., resulting in defects such as poor billet quality. Summary of the Invention

[0005] In order to improve the quality of the cast billet, the present application provides a crystallizer cooling system based on reducing the inlet water temperature.

[0006] The present application provides a crystallizer cooling system based on reducing the inlet water temperature, which adopts the following technical solutions:

[0008] By adopting the above technical solution, the cooling water flows back to the heat sink through the return pipe. At this time, the rotating motor rotates the first worm gear through the first worm, and the first worm gear rotates the heat sink, so that the heat sink throws out the cooling water inside itself. In the process of throwing out, the heat dissipation area of ​​the cooling water is increased, so that the cooling water dissipates heat more quickly, and then the circulating water in the water pool is quickly cooled down. The thermal energy of the circulating water is lower, the cooling efficiency is guaranteed, and thermal cracks on the surface of the billet and internal pores, inclusions, etc. are not easy to appear, thereby achieving the effect of improving the quality of the casting.

The spur gears rotate the first baffle via the first roller, thereby opening the first water trough. Water in the first water injection tank enters the crystallizer through the first water trough. When the drive assembly stops driving the spur gears to rotate, the first telescopic spring releases its elastic force to reset the first baffle, thereby closing the first water trough. Through the above structure, the first water troughs are opened in sequence, the position where the first water injection tank injects water into the crystallizer is continuously changed, and the cooling water temperature gradient on both sides of the crystallizer is reduced, thereby further improving the quality of the cast billet.

[0011] Optionally, the driving assembly includes a linkage roller, a second worm and a driving motor. A base is provided on one side of the crystallizer, and a support plate is fixedly provided on the upper surface of the base.

During the rotation process, only one of the spur gears on the same side is engaged with the half gear at a time. When the spur gear is engaged with the half gear, the half gear drives the spur gear to rotate, thereby achieving the effect of only one spur gear on the same side rotating at a time.

[0013] Optionally, a first telescopic rod is provided in the first telescopic spring, one end of the first telescopic rod is hinged to the first limit plate, and the other end of the first telescopic rod is hinged to the first baffle.

[0016] By adopting the above technical solution, the first roller rotates the second driven gear via the second driving gear, which in turn rotates the second roller, which in turn rotates the second baffle, thereby opening the second water trough. Water in the second water injection tank enters the crystallizer through the second water trough. When the first telescopic spring releases its force, the first roller resets via the second driven gear and the second driving gear, resetting the second roller. This resets the second baffle and closes the second water trough. Through this structure, the second water troughs are opened sequentially, continuously changing the position at which the second water injection tank injects water into the crystallizer, reducing the cooling water temperature gradient at both ends of the crystallizer, and further improving the quality of the cast billets.

The number of the water baffles 10 is the same as the number of the water outlet grooves 231 and corresponds one to one. Connecting rods 101 are fixed at both ends of the water baffle 10, and the end of the connecting rod 101 away from the water baffle 10 is fixedly connected to the heat dissipation tank 23.

[0065] refer to Figure 8 and Figure 9 A first worm 24 is provided horizontally on one side of the pool 2, and both ends of the first worm 24 are sleeved with hanging rings 241, and the hanging ring 241 is rotatably connected to the first worm 24. A hanging rod 25 is fixed horizontally between the hanging ring 241 and the pool 2, and one end of the heat dissipation tank 23 away from the connecting pipe 2331 is sleeved with a first worm gear 232 that meshes with the first worm 24, and the first worm gear 232 is fixedly connected to the heat dissipation tank 23. A fixing seat 26 is fixed on the outer wall of the pool 2, and a rotating motor 261 that drives the first worm 24 to rotate is installed on the upper surface of the fixing seat 26.

[0066] The rotating motor 261 starts to drive the first worm 24 to rotate, the first worm 24 drives the first worm gear 232 to rotate, and the first worm gear 232 drives the heat sink 23 to rotate. The heat sink 23 rotates to throw out the cooling water inside itself, so that the cooling water hits the surface of the water baffle 10, and finally the cooling water falls into the water pool 2 for circulation.

[0067] The implementation principle of the crystallizer cooling system based on lowering the inlet water temperature in the embodiment of the present application is as follows: the cooling water in the water pool 2 is pressurized by the pressure pump station 21 and then injected into the first water injection tank 3 and the second water injection tank 6 through the first water injection pipe 211 and the second water injection pipe 212 respectively. At this time, the first baffle 313 and the second baffle 613 are driven to open and close in sequence by the driving component 4, so that the first water injection tank 3 and the second water injection tank 6 are respectively uniformly injected into the crystallizer 1 through each first water flow trough 311 and each second water flow trough 611. The cooling water in the crystallizer 1 flows into the return pipe 81 through the first return pipe 11 and the second return pipe 12. The cooling water in the return pipe 81 flows into the temporary storage tank 8. The cooling water in the temporary storage tank 8 flows into the connecting pipe 2331 through the connecting pipe 82. The cooling water in the connecting pipe 2331 flows into the heat dissipation tank 23. The heat dissipation tank 23 rotates to throw out the cooling water, so that the cooling water hits the water baffle 10 and falls into the water pool 2 for circulation. Through the above structure, the effect of improving the quality of the casting billet is achieved.

[0068] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
