1. The continuous evaporation crystallizer shall be carefully inspected before casting. If water seepage and water leakage are found, it shall be replaced immediately. The copper plate scar depth on the working surface of the inner cavity of the continuous evaporation crystallizer shall not exceed 1.5mm.
2. All kinds of water pipes, valves and secondary cooling nozzles must be unblocked, the water volume and water pressure bell system must be good, and the electrical and mechanical equipment shall meet the casting requirements. In case of water cut-off or continuous evaporation of a large amount of steam in the crystallizer during casting, the pouring shall be stopped immediately.
3. It is mainly completed by the internal cooling water. The forced water spray cooling crystallization cavity in the crystallizer accessories can effectively take away the heat of molten steel quickly, but the corresponding preconditions must be met for the smooth completion of this operation.
continuous crystallizer has higher cost performance due to the reduction of material price. It does not need complex procedures for installation and use. Because of this material, this type of crystallizer is widely used in many fields, with a wide range of applications, and its promotion is also increasing. With the development of society, the application range will gradually expand.

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