Characteristics of sintered calcium aluminate:
1) Uniform chemical composition, low melting point and fast melting speed can shorten the refining time;
2) No fluorine, no erosion of furnace lining and ladle;
3) Compact structure, no water absorption, easy storage and transportation;
4) Due to the stable phase and fast slag formation, it can reduce the dust pollution to the iron and steel plant and comprehensively stabilize the refining process;
5) It does not contain impurities such as hydrogen, nitrogen and carbon, which is conducive to improving the quality of steel.
Sintered calcium aluminate (premelted aluminum calcium slag) is mainly used in LF furnace, open hearth furnace and converter ladle refining to remove impurities such as sulfur and oxygen in molten steel and reduce the content of harmful elements and impurities in steel. It is suitable for ordinary carbon steel, high carbon steel, high and low alloy steel.
