Pre-melting calcium aluminate

Product Details:

Description of Pre-melting Calcium Aluminate
Pre-melting calcium aluminate for refined steel-making is newly developed by our company.It is produced through selecting material of high quality, melting the material in electro-furnace, cooling, crashing and screening into different sizes. This product can be divided into following types:CaO-Al2O3,CaO-SiO2-Al2O3-MgO and CaO-Al2O3-BaO-CaF2.We can also adjust and produce the product according to customers' requirement.

Character & uses for the Pre-melting calcium aluminate
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.
