The basic conditions of the mould assembly:
In order to obtain qualified casting billets, the basic conditions that the mould assembly should meet are:
(1) It has good thermal conductivity, so that the molten steel can quickly condense and form.
(2) It has good wear resistance to extend the life of the mould assembly, reduce the maintenance workload and the time of replacing the mould assembly, and improve the operation rate of the continuous casting machine.
(3) It has sufficient rigidity, especially in the case of chilling and heating, and a large temperature gradient. Small deformation is required.
(4) The structure is simple, compact, easy to manufacture, easy to disassemble and assemble, and easy to adjust. The cooling water circuit can be connected by itself for quick replacement; the dead weight is small to reduce the inertia force when the mold is vibrating and reduce the drive of the vibration device Power, and make the crystallizer vibrate smoothly.

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