Inkqubo yokucoca ngokubanzi imalunga noku kulandelayo:
1. Qala ukuthoba inqanaba lezinto ezisibhozo ngaphambi kokucokisa ukunciphisa ukuqokelelana kwezinto ezingama-75 ze-ferrosilicon kwisithando somlilo.
2. Emva kokuba isithando somlilo sokugqibela se-75 Ferrosilicon sigqityiwe, iifayili zentsimbi (ngokuqhelekileyo iibhloko zensimbi ezilahliweyo) zongezwa. Imali eyongeziweyo idla ngokulingana okanye iphezulu kancinane kunexabiso lentsimbi eveliswa kwiziko ngalinye lokunyibilikiswa okuqhelekileyo kwe-75 Ferrosilicon (kufuneka kuqwalaselwe Kuxhomekeka kwizinto ezifana neqondo longenelelo olusezantsi lweziko okanye ubungakanani bentsimbi etyhidiweyo eqokelelwe ezikweni) , I-45 ferrosilicon iya kukhutshwa emva kwe-1 kwiiyure ze-1.5. Ngokohlalutyo lwesampulu yentsimbi phambi kwesithando somlilo, ukuba i-silicon iphezulu, inani elifanelekileyo leentsimbi zetsimbi linokongezwa kwi-ladle yensimbi etyhidiweyo; ukuba i-silicon iphantsi, inani elifanelekileyo le-75 ye-ferrosilicon inokongezwa (imali eyongezelelweyo yi-45 ferrosilicon ngetoni. Ukwandisa i-silicon nge-1%, i-silicon ye-75 kufuneka yongezwe Kubalwa ngokusekelwe kwi-12 ukuya kwi-14 yeekhilogram zentsimbi).
3. Emva kokufaka izilaphu zentsimbi, unokongeza intlawulo ye-ferrosilicon engama-45.
Umzekelo: kukho i-3000 yeekhilogram ze-ferrosilicon kwi-ladle yensimbi etyhidiweyo, kwaye umxholo we-Si uhlalutywe phambi kokuba iziko liyi-50%, ngoko ubungakanani bentsimbi yentsimbi ekufuneka yongezwe kwileyidi yentsimbi etyhidiweyo yile:
3000×(50/45-1)÷0.95=350kg
