I-Calcium Silicon Alloy yi-alloy yokubini ye-silicon kunye ne-calcium, amacandelo ayo aphambili yi-silicon kunye ne-calcium, kodwa iqulethe izixa ezahlukeneyo zentsimbi, i-aluminium, i-carbon, isulfure kunye ne-phosphorus kunye nezinye isinyithi.
Ngenxa yobudlelwane obuqinileyo phakathi kwekhalsiyam kunye neoksijini, isulfure, ihydrogen, initrogen kunye nekhabhoni kwintsimbi engamanzi, iCalcium Silicon Alloy isetyenziselwa i-deoxidation, i-degassing kunye nokulungiswa kwesulfure kwintsimbi engamanzi, i-calcium silicon emva kokongeza intsimbi engamanzi ivelisa isiphumo esinamandla se-exothermic. calcium iba ngumphunga wekhalsiyam kwintsimbi elulwelo, ifuthe ifuthe kwintsimbi engamanzi, nto leyo eluncedo ukudada inclusions non-metallic. Emva kwe-deoxidation, i-silicon calcium alloy ivelisa i-non-metallic inclusions kunye neengqungquthela ezinkulu kunye nokulula ukudada, kwaye iphinde iguqule imilo kunye neempawu ze-non-metallic inclusions. Ke ngoko, i-silicon calcium alloy isetyenziselwa ukuvelisa intsimbi ecocekileyo, intsimbi ekumgangatho ophezulu eneoksijini ephantsi kunye nomxholo wesulfure, kunye nentsimbi ekhethekileyo eneoksijini ephantsi kakhulu kunye nomxholo wesulfure.
