Kubera ko calcium ifitanye isano ikomeye na ogisijeni, sulfure, hydrogène, azote na karubone mu byuma bishongeshejwe, calcium silicon alloy ikoreshwa cyane cyane mu kwangiza, kwangiza no gutunganya sulfure mu byuma bishongeshejwe. Kalisiyumu silicon itanga ingaruka zikomeye iyo yongewe kumashanyarazi.
Kalisiyumu ihinduka imyuka ya calcium mu byuma bishongeshejwe, bikurura ibyuma bishongeshejwe kandi bigira akamaro mu kureremba kutari ibyuma. Nyuma ya calcium silicon alloy isukuye, ibyongeweho bitari ibyuma bifite ibice binini kandi byoroshye kureremba birakorwa, kandi imiterere nimiterere yibintu bitari ibyuma nabyo birahinduka. Kubwibyo, calcium silicon alloy ikoreshwa mugukora ibyuma bisukuye, ibyuma byujuje ubuziranenge bifite ogisijeni nkeya na sulfure, hamwe nicyuma kidasanzwe gifite ogisijeni nkeya na sulferi. Ongeramo calcium silicon alloy irashobora gukuraho ibibazo nka nodules kuri ladle nozzle yicyuma ukoresheje aluminium nka deoxidizer ya nyuma, hamwe no kuziba tundish nozzle mugukomeza ibyuma | gukora ibyuma.
Mu buhanga bwo gutunganya itanura ryo hanze y’icyuma, ifu ya calcium silikate ya pisitori cyangwa insinga yibanze bikoreshwa mukwangiza no kugabanya imyuka ya ogisijeni na sulfuru biri mu byuma bikagera ku rwego rwo hasi cyane; irashobora kandi kugenzura imiterere ya sulfide mubyuma no kunoza ikoreshwa rya calcium. Mu gukora ibyuma bikozwe mu cyuma, usibye kwangiza no kweza, calcium silicon alloy nayo igira uruhare mu kurera, ifasha gukora grafite nini nziza cyangwa ifatika; irashobora gukwirakwiza grafite mu cyuma cyijimye kandi ikagabanya imyumvire yo kwera; irashobora kandi kongera silicon na desulfurize, kuzamura ubwiza bwibyuma.
