Description

Technical Field

[0001] The utility model relates to the technical field of crystallizers, in particular to an anti-loosening combined crystallizer. Background Art

[0002] The crystallizer is an important equipment in the continuous casting production line, which is used to uniformly cool and solidify the high-temperature liquid metal (such as steel) into a continuous casting billet. The crystallizer mainly consists of components such as the crystallizer shell, the crystallizer copper tube, the crystallizer cooling water system, the crystallizer roller and the crystallizer support device. These components cooperate with each other to ensure that the high-temperature liquid metal is uniformly cooled and solidified in the crystallizer, thereby forming a continuous casting billet. Among them, the crystallizer cooling water system mainly refers to the water jacket set outside the crystallizer copper tube. The water jacket and the crystallizer copper tube are connected with coolant, and the heat is transferred and controlled by heat conduction, thereby realizing the control and regulation of the crystallizer temperature, ensuring that the temperature in the crystallizer is kept within an appropriate range, thereby realizing the control and optimization of the crystallization process. However, due to the change in temperature, the water jacket has a certain expansion coefficient, and the joint part is prone to loosening at high temperature, which leads to leakage of coolant, affecting processing stability and production safety.

The above patent greatly improves the deformation resistance of the crystallizer copper tube and the gap accuracy of the water seam by arranging fixing bolts connected to the crystallizer copper tube on the inner water jacket and arranging reinforcing ribs surrounding the outer surface of the inner water jacket, but does not enhance the deformation resistance and sealing effect of the water jacket, affecting the overall stability of use.
