Ebe ọ bụ na calcium nwere njikọ siri ike na oxygen, sọlfọ, hydrogen, nitrogen na carbon na nchara a wụrụ awụ, a na-ejikarị calcium silicon alloy eme ihe maka deoxidation, degassing na fixation nke sọlfọ na ígwè a wụrụ awụ. Calcium silicon na-emepụta mmetụta exothermic siri ike mgbe agbakwunyere na nchara a wụrụ awụ.

Calcium na-atụgharị ghọọ uzuoku calcium n'ime ígwè a wụrụ awụ, nke na-akpali nchara a wụrụ awụ ma na-aba uru na-ese n'elu mmiri nke na-abụghị ọla. Mgbe calcium silicon alloy na-deoxidized, na-abụghị metal inclusions na ibu irighiri na mfe sere n'elu, na ọdịdị na Njirimara nke na-abụghị metal inclusions na-agbanwekwa. Ya mere, a na-eji calcium silicon alloy na-emepụta ígwè dị ọcha, ígwè dị elu nke nwere obere ikuku oxygen na sọlfọ, na ígwè ọrụ pụrụ iche nke nwere oke ikuku oxygen na sọlfọ dị ala. Ịgbakwunye calcium silicon alloy nwere ike iwepụ nsogbu ndị dị ka nodules na ladle nozzle nke ígwè na-eji aluminum dị ka ihe ikpeazụ deoxidizer, na ngọngọ nke tundish nozzle na-aga n'ihu nkedo ígwè | ime ígwè.

Na n'èzí-ọkụ refining technology nke ígwè, calcium silicate ntụ ntụ ma ọ bụ isi waya na-eji maka deoxidation na desulfurization iji belata oxygen na sọlfọ ọdịnaya n'ime ígwè ka nnọọ ala larịị; ọ nwekwara ike ijikwa ụdị sulfide na nchara ma melite ọnụego ojiji nke calcium. Na mmepụta nke ígwè nkedo, na mgbakwunye na deoxidizing na ime ka ọ dị ọcha, calcium silicon alloy na-arụkwa ọrụ na-azụlite, na-enyere aka ịmepụta ihe dị mma ma ọ bụ graphite; ọ nwere ike kesaa graphite n'otu n'otu na ígwè nkedo isi awọ ma belata ọchịchọ nke ịcha ọcha; ọ nwekwara ike ịbawanye silicon na desulfurize , melite ogo nke nkedo ígwè.
