Steelmaking Fused Calcium Aluminate Synthetic Slag Used High Melting Speed
Calcium Aluminate for Metallurgy is a kind of auxiliary material for steelmaking, as it speeds up secondary metallurgy process, especially faster desulfurization, Improves overall steel cleand makes high grade steel with cheaper cost.
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 se and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and suppresses srus into molten steel;
4) Improving the protective effect and reducing erosion to ladle lining.
