Sintered Calcium Aluminate ( Sintered Refining Slag) is calcined in the rotary kiln with the high quality raw materials.
It is featured by uniform chemical composition, low melting point and high melting speed for becoming dreg in short time, reducing the energy consumption and dust pollution in the steel plant.
It is mainly used for desulphurization, deoxidation and impurity absorption in the process of refined steelmaking for general carbon steel, high carbon steel, high and low alloy steel.
