Hloov steelmaking calcium silicon Si40 Fe40 Ca10
Txij li calcium muaj kev sib raug zoo nrog oxygen, sulfur, hydrogen, nitrogen thiab carbon nyob rau hauv molten steel, silicon-calcium alloys yog tsuas yog siv rau deoxidation, degassing thiab fixation ntawm leej faj nyob rau hauv molten hlau.Calcium silicon ua rau muaj zog exothermic nyhuv thaum ntxiv rau molten hlau.Calcium hloov mus rau hauv calcium vapor nyob rau hauv molten steel, uas muaj ib tug stirring nyhuv ntawm molten steel thiab yog zoo rau lub floating ntawm non-metallic inclusions.
