Calcium Aluminate Synthetic Slag

Product Details:

Description of Calcium Aluminate Synthetic Slag
As a steel refining addition, Calcium Aluminate Synthetic Slag is a kind of auxiliary material for steelmaking. Calcium Aluminate 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 Synthetic Slag is CA, CA2, C3A and C12A7.

Applications of Calcium Aluminate Synthetic Slag
Calcium Aluminate Synthetic Slag is used in steel making process specially for desulphurizationdephosphorization and non-metallic inclusion absorption without adversely affecting ladle refractory. Calcium Aluminate Synthetic Slag can play a role of thermal insulation; Calcium Aluminate Synthetic Slag can purify liquid steel by preventing steel from reacting with OxygenNitrogenHydrogen. Calcium Aluminate synthetic slag is widely used as a steel making addition in most large-scale steel corporation in JapanUSA and European countries.

Benefits Of Calcium Aluminate Synthetic Slag
1. Low melting(≤1400), low viscosity of melting-slag, optimum fluidity
2. High performance of desulphurization and non-metallic inclusion absorption
3. Energy savings, Ladle refractory protection and the life of ladle prolonging
4. Faster steel refining times and better refining performance
5. Savings on the elimination or reduced consumption, cost effective, production efficient
6. Form slag quickly, avoid moisture absorption, never get powder, environment friendly   

 Using Method of Calcium Aluminate Synthetic Slag
Calcium Aluminate Synthetic Slag can be added into ladle bottom once before slag-removing. The dosage of Calcium Aluminate Synthetic Slag will be depended on production on site. The reference dosage is 6-8kg per ton of steel. There is another method. Calcium Aluminate Synthetic Slag can be added twice, half dosage in ladle bottom at the first time, then put the last with steel flowing. Make sure ventilate at the bottom of ladle. Make the air and slag in steel go up float completely. Keep the steel liquid temperature and chemical composition consistent.

 Package of the Calcium Aluminate Synthetic Slag
Calcium Aluminate Synthetic Slag is available in ton-jumbo bag. Other packing is according to customer’s requirement.
