Calcium aluminate advantages:

 

1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time;

 

2) It has no fluoride and doesn’t erode furnace lining and ladle, and it is compact, non-absorbent,and easy to storage as well;

 

3) Stable phase and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and suppresses phosphorus into molten steel;

 

4) Improving the protective effect and reducing erosion to ladle lining.

 

 

Remark: specification and size can be optimized by per customer' requirement
