As a steel refining addition, Calcium Aluminate for Synthetic Slag is a kind of auxiliary material for steelmaking. Calcium Aluminate for Synthetic Slag is made of select raw material of Calcium and Aluminate, blended at a proper proportion, ground to powder, pelletized after churning , sintered or melted in kiln. The mineral composition of Calcium Aluminate for Synthetic Slag is CA, CA2, C3A and C12A7.

We handle all grades of calcium aluminate. Usually we divide them into 2 types, sintered type and premelting type. Sintered type is calcined in rotary kiln, tunnel kiln and other kilns with fuels of gas and coal. Fused type is from electric arc furnace (EAF) only. Our annually output is 100000 tons and our products are exported to the steel mills in Korea, Japan, Indonesia, Singapore, Malaysia, Turkey and Etc.

The premelting specifications are as below:

Al2O3:35%min, CaO:45%min , Fe2O3:1.5%max TiO2:1.5  Max
SiO2: 5.0%max , H2O:0.50%max,

Size:0-50mm.

The sintered type we can offer is as below:

Al2O3:53%min, CaO:32%min , Fe2O3:3.0%max 
SiO2: 6.5%max , MgO<1.0%

Size:0-30mm.
