铝酸钙又叫精炼渣， 因其成分均匀、熔点低熔速快、可缩短冶炼时间等特点，正越来越受炼钢工作者的重视。 Sintered calcium aluminate is also called refining slag. Due to its characteristics of uniform composition, low melting point, fast melting speed, and shortening the smelting time, it is getting more and more attention from steelmaking workers. 不含氟，保护生态环境，不浸蚀炉衬； 不吸水，便于储存、运输； 由于成分均匀、成渣快，可减少钢铁厂粉尘污染； 不含氢、氮、碳等杂质，以及良好的冶金效果，有利于提高钢材质量。 Uniform composition, low melting point and fast melting speed, can shorten the smelting time; non-fluorine, protect the ecological environment, do not etch the furnace lining; do not absorb water, easy to store and transport; due to uniform composition and fast slag formation, it can reduce dust pollution in steel plants; Does not contain impurities such as hydrogen, nitrogen, carbon, and good metallurgical effects, which is conducive to improving the quality of steel.
It is mainly used for refining outside steel and metallurgical furnaces.
