Calcium Aluminate
Calcium Aluminate Back to Refractories

 

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.
