Abstract:

The raw material, proportioning ratio and production process for water free stopping mix for blast furnace tapping hole are described. At present under the condition of high capacity of blast furnace,the stopping mix for blast furnace tapping hole is developed in the directions of high strength, high corrosion resistance, long service life and environmental protection. Emphasis should be given to improve the structure and properties of the stopping mix for blast furnace tapping hole to produce a high quality stopping mix.
