calcium aluminate has the following characteristics:
1. homogeneous, low melting point, melting fast, can shorten the refining time;
2. has a certain amount of sulfur melt, with addition of a small amount of lime used directly for hot metal desulfurization activity, and promote the removal of sulfur in steel, aluminum on steel, silicon and other oxides adsorption. Reduce non-metallic inclusions in steel. Help to improve the quality of steel;
3. erosion of the ladle lining and light, is the best substitute for fluorite;
4. non-absorbent, easy storage and transport;
5. the ingredients evenly, into the slag quickly, can reduce the steel plant dust
