The material has excellent construction property and drying property, can suit the conditions of various steelworks and meet the requirement of large scale production with time saving, labor saving and high work efficiency. It is corrosion resistant and peeling resistant. Integral concreting is carried out according to the using condition of ladle and slag line casting, various positions can be kept synchronous, and service life is greatly enhanced, and the tension situation of ladle turnover is eased.

The product has good integrity at high temperature, reducing the accident of ladle puncturing and missing. Peeling casting can be realized to save material and reduce ton steel refractory consumption.
