I-Ferrosilicon iwuhlobo lwe-ferroalloy olwakhiwa ngokuncishiswa kwe-silica noma isihlabathi nge-coke lapho kukhona insimbi.Imithombo ejwayelekile ye-iron insimbi eyi-scrap noma i-millscale.Ama-Ferrosilicons anokuqukethwe kwe-silicon afika cishe ku-15% enziwa ezithandweni eziqhumayo ezifakwe izitini zomlilo ezine-asidi.Ama-Ferrosilicons anokuqukethwe okuphezulu kwe-silicon enziwa ezithandweni zikagesi ze-arc.Ukwakhiwa okujwayelekile emakethe ama-ferrosilicons ane-silicon engu-60-75%.Okusele kuyinsimbi, cishe u-2% ohlanganisa ezinye izakhi ezifana ne-aluminium ne-calcium.Ukuchichima ngokweqile kwe-silica kusetshenziselwa ukuvimbela ukwakheka kwe-silicon carbide.
Isicelo:
①Njenge-deoxidizer ne-alloy embonini yokwenza insimbi
②Njenge-ejenti egomelayo ne-spheroidizing kunsimbi ewugqinsi
③Njenge-ejenti eyehlisayo ekukhiqizweni kwe-ferroalloy
④Njenge-ejenti esusayo ekuncibilikisweni kwe-magnesium
⑤Kwezinye izinkambu ze-aplocation, i-silicon iron powder egayiwe noma e-atomizing ingasetshenziswa njengesigaba esimisiwe.
