The treatment of copper mould tube after scaling
1. Extract the scale sample on the copper mold tube for analysis. If the surface of copper mold tube turns green, it may be oxidized and corroded;
2. Test whether the effluent quality of soft water meets the standard
3. If the quality of soft water can not be improved, it is necessary to consider adding scale inhibitor.

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