The products are one kind of spray coating mix,made of high-strength, light-weight refractories with various kinds of micro-powders as additivies and the advance processes,widely used in various of tubes of blast furnace and hot stove,ordinarily used in gas tube and descended tube at the top of blast furnace,hot blast main pipe,packing tube and flue lining etc.
The products have the advantages of resistance to high-temperature wear,low shrinkage rate at high-temperature,low thermal conductivity,spalling resistance,resistance to CO gas corrosion,solving the problem of strength not in line with insulation,resulting in longer service life.
