The required performance and classification of the crystallizer
1) It has good thermal conductivity and can quickly form a primary green shell of sufficient thickness.
2) It has good structural rigidity and structural manufacturability, easy to manufacture, install and adjust.
3) It has better wear resistance and longer life.
4) The weight should be light and the cost should be low.
The crystallizer is lined with copper and copper alloy with very good thermal conductivity, and the outer jacket is covered with water for cooling. The structure is divided into three parts: copper inner wall, outer jacket and water tank. The material used to make the crystallizer requires good thermal conductivity, high strength, small expansion at high temperatures, easy cutting and surface treatment.
According to the external shape, the crystallizer can be divided into straight crystallizer and arc crystallizer. The former is used on vertical and vertical bending continuous casting machines, and the latter is used on arc and elliptical continuous casting machines.
According to the shape of the casting billet, the crystallizer can be divided into square billet, slab, rectangular billet, round billet and special-shaped section crystallizer;
According to the structure, the crystallizer can be divided into integral type, tube type, combined type and adjustable width crystallizer.

In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
