Calcium Aluminate Clinker is produced by burning the raw materials of high grade crude aluminous bauxite andlimestone in arc-furnace kiln. It is mainly used in refiningladle to remove the sulfide impurities from steel liquid and keeping good fluidity of slag. Physical performance and use (1) Low melting (≤1370 ), low viscosity of melting slag, good flowing property, short time for slag-forming; (2) Big sulfur absorption capacity of slag stream; good desulphurisation, oxygen-removing and phosphorus-taking off properties; efficiently absorbing the impurities in the steel at the same time. (3) Capable to increase the refining efficiency and the life of steel ladle largely. Specifications.
