Fused calcium aluminate (Premelted calcium aluminates residue) is mainly used for separating the impurity elements such as sulfur and oxygen in ladle refining of LF furnace, open hearth furnace and the converter furnace, and it can reduce the content of harmful elements and impurities, which is applicable for general carbon steel, high carbon steel, high and low alloy steel. Its applications have already been mature in some foreign countries, such as South Korea, Japan, the United States and the developed European countries
