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.
