Calcium aluminate advantages: 1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time; 2) It has no fluoride and doesnt 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.
