Uses of filler sand in the steel industry

High-efficiency filler sand is composed of high-quality imported chromium ore sand, refined quartz sand and high-refractory materials. It has the advantages of good fluidity, high specific gravity, fast speed, appropriate sintering layer, resistance to erosion and penetration of molten steel, and the self-flowing pouring rate of the ladle can reach more than 99%. It reduces oxygen blowing and drainage, improves the quality and stability of steel products, and ensures the smooth progress of the continuous casting process.
