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
