Calcium Aluminate Clinker is produced by burning the raw materials of high grade crude aluminous bauxite and limestone in rotary kiln. It is mainly used in refining ladle to remove the sulfide impurities from steel liquid and keeping good fluidity of slag. After grinded into cement, it turns to refractory cement, also named high alumina cement and is used as the bonding agent of refractory concrete.

 Physical performance and use

(1) Low melting (¡Ü1370¡æ), 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.
