Pre-Melting Calcium Aluminate

Description of the pre-melting calcium aluminate

Pre-melting calcium aluminate for refined steel-making is newly developed by our company. It is produced by selecting material of high quality, melting the material in electro-furnace, cooling, crashing and screening into different sizes.

Character & uses for the Pre-melting calcium aluminate

Low Melting Point and good fluidity
Quick melting speed, good liquidity and good lubrication make the desulphurization more efficiency.
Excellent security
It is mainly used for desulphurization and temperature preservation in high quality steel-making.

Size of the Pre-melting calcium aluminate

1~30mm or produce according to clients requirements
