The product adopt the advanced technology of composite carbon and carbon-free to increase the fire resistance, with long holding time, small capacity, good performance, small thermal conductivity, pour rate of more than 90%, small dust flying, non-stick wall and other advantages.

It is suitable for alkaline magnesium and magnesium calcium lining. When casting ultra-low carbon clean steel, it can adsorb impurities of molten steel with special effect, which can improve the stability of continuous casting slag and ensure the variety quality of steel.
