Description

Technical Field

[0002] The crystallizer is the most critical component of the aluminum alloy slab continuous casting machine. Its structure, material and performance parameters play a decisive role in the quality of the ingot and the production capacity of the casting machine. It is a continuous steel casting equipment that injects molten steel from the intermediate tank and solidifies it into a solid ingot shell according to the specified cross-sectional shape.

[0003] For example, announcement number CN216226845U discloses an aluminum alloy flat ingot casting crystallizer, including a frame plate, a mounting plate, a variable pitch cylinder, an intermediate cavity and an angle adjustment mechanism; with this arrangement, the angle of the side plate can be adjusted by the angle adjustment mechanism, thereby changing the angle on both sides of the intermediate cavity, and the alloy ingot with a trapezoidal small face shape can be conveniently cast, and the side inclination is adjustable, the overall structure is simple, and it is easy to use.

[0004] However, the key components of the crystallizer include the heat-conducting copper tube and the water jacket cavity. When the cooling water circulates to cool down the mold, whether soft water or normal water source is used, scale will inevitably be generated, which will block the water jacket cavity and make it impossible to cool down the heat-conducting copper tube normally. At the same time, scale enters the water jacket cavity and adheres to the outside of the heat-conducting copper tube, causing the heat-conducting copper tube to lose temperature locally and burst.
