Character & uses for the REFMAT Pre-melting calcium aluminate

REFMAT Pre-melting calcium aluminate  for refined steel-making is gained through melting method and therefore it possesses more merits than other clinkers: The composition is consistent.

The low melting point, quick melting speed, good liquidity and good lubrication make the desulphurization more efficiency.

The product is clumps or grains so that dust pollution in smelting can be greatly reduced.

It is mainly used for desulphurization and temperature preservation in high quality steel-making. 

 Size of Pre-melting calcium aluminate

1～30mm or produce according to clients requirements

Products type and specifications:

Package of Pre-melting calcium aluminate

1000kg/1200kg/1250kg in big bag, other packing according to the demand of a customer.
