In order to obtain a qualified casting billet, the basic conditions that the mold should meet are
(1) It has good thermal conductivity, so that copper water can quickly condense and form;
(2) It has good wear resistance to extend the life of the mold , Reduce the maintenance workload and time to replace the mold, improve the operation rate of the continuous casting machine;
(3) have sufficient rigidity, especially in the case of chilling and heating, and large temperature gradients, small deformation is required;
(4) The structure is simple and compact, easy to manufacture, easy to disassemble and assemble, easy to adjust, and the cooling water circuit can be connected by itself for quick replacement; the self-weight is small to reduce the inertial force when the mold is vibrating and reduce the driving power of the vibration device, and make the crystal The vibration of the device is stable.

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