Details

Calcium Aluminate for Metallurgy is a kind of auxiliary material for steelmaking,  as it speeds up secondary metallurgy process, especially faster desulphurization, Improves overall steel cleanliness and makes high grade steel with cheaper cost.Its applications have already been mature in some foreign countries, such as South Korea, Japan, the United States and the developed European countries.

Fused 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.
