Daub, dry lining
WTM coating has the characteristics of good adhesion, strong bursting resistance, corrosion resistance, peeling resistance, and not easy to react with the base material. Especially magnesium, magnesium calcium continuous casting dry lining construction is convenient, can reduce the pollution of molten steel, continuous pouring time increased significantly, the maximum service life has reached more than 50 hours, for steel mills to reduce production costs
