Fused Calcium Aluminate

Fused Calcium Aluminate(synthetic refining slag) is produced by fusing the quality raw materials in the electric arc furnace.

It is featured by uniform chemical composition, low melting point and high melting speed for becoming dreg in short time, reducing the energy consumption and dust pollution in the steel plant.

It is mainly used for desulphurization, deoxidation and impurity absorption in the process of refined steelmaking for general carbon steel, high carbon steel, high and low alloy steel.
