1.Pre-melted calcium aluminate description:

Pre-melted calcium aluminate for steel refining 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.

Pre-melted calcium aluminate 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.

Pre-melted calcium aluminate is mainly used for desulphurization and temperature preservation in high quality steel-making.

2. Pre-melted calcium aluminate Specifications:

CaO 49 – 54%

Al2O3 41 – 45%

SiO2 <3.8%
