I-Calcium Silicon Alloy iyingxubevange ye-silicon ne-calcium, izingxenye zayo eziyinhloko ziyi-silicon ne-calcium, kodwa futhi iqukethe amanani ahlukene ensimbi, i-aluminium, i-carbon, isulfure ne-phosphorus nezinye izinsimbi.
Ngenxa yokuhlobana okuqinile phakathi kwe-calcium ne-oxygen, isulfure, i-hydrogen, i-nitrogen ne-carbon ku-liquid steel, i-Calcium Silicon Alloy isetshenziselwa kakhulu ukuqeda amandla, ukukhipha umoya nokulungisa isibabule ensimbi ewuketshezi, i-calcium silicon ngemva kokwengeza insimbi ewuketshezi ikhiqiza umphumela oqinile we-exothermic, i-calcium iba umhwamuko we-calcium ensimbini ewuketshezi, umphumela onyakazayo kunsimbi ewuketshezi, okulungele ukuntanta kokuhlanganisa okungezona ezensimbi. Ngemuva kwe-deoxidation, i-silicon calcium alloy ikhiqiza i-non-metallic inclusions enezinhlayiya ezinkulu futhi kulula ukuntanta, futhi ibuye iguqule ukuma kanye nezakhiwo ze-non-metallic inclusions. Ngakho-ke, i-silicon calcium alloy isetshenziselwa ukukhiqiza insimbi ehlanzekile, insimbi yekhwalithi ephezulu enomoya-mpilo ophansi nesibabule, kanye nensimbi ekhethekile enomoya-mpilo ophansi kakhulu nesibabule.
