Ukongeza ekusetyenzisweni ukwenza intsimbi, i-ferrosilicon ikwasetyenziswa njenge-deoxidizer ekunyibilikiseni isinyithi se-magnesium. Inkqubo yokwenza intsimbi yinkqubo apho isinyithi esinyibilikisiweyo sichithwa kwaye sisusa ukungcola okuyingozi okufana ne-phosphorus kunye nesulfure ngokuvuthela i-oksijini okanye ukongeza i-oxidants. Ngethuba lenkqubo yokwenza isinyithi kwintsimbi yehagu, umxholo we-oksijini kwintsimbi etyhidiweyo ukhula ngokuthe ngcembe, kwaye ngokuqhelekileyo imelwe yi-FeO ikhona kwintsimbi etyhidiweyo. Ukuba i-oksijini engaphezulu eshiywe kwintsimbi ayisuswanga kwi-silicon-manganese alloy, ayikwazi ukuphonswa kwi-billet yensimbi efanelekileyo, kwaye isinyithi esineempawu ezintle zomatshini azikwazi ukufunyanwa.
Ukwenza oku, kuyimfuneko ukongeza ezinye izinto ezinamandla okubopha i-oksijini kunentsimbi, kwaye i-oxides yayo kulula ukuyikhupha kwintsimbi etyhidiweyo kwi-slag. Ngokokuqina okubophelelayo kwezinto ezahlukeneyo kwintsimbi etyhidiweyo ukuya kwioksijini, ukulandelelana ukusuka buthathaka ukuya komelele ngolu hlobo lulandelayo: chromium, manganese, carbon, silicon, vanadium, titanium, boron, aluminium, zirconium, kunye necalcium. Ke ngoko, iialloyi zentsimbi ezenziwe ngesilicon, imanganese, ialuminiyam, kunye nekhalsiyam zisetyenziswa ngokuqhelekileyo ukwenza i-deoxidation kwi-steelmaking.
Isetyenziswa njenge-arhente yokudibanisa. Izinto ze-alloying azikwazi ukunciphisa kuphela ukungcola kwintsimbi, kodwa zilungelelanise ukubunjwa kweekhemikhali zensimbi. Izinto ezisetyenziswa ngokuqhelekileyo zibandakanya i-silicon, i-manganese, i-chromium, i-molybdenum, i-vanadium, i-titanium, i-tungsten, i-cobalt, i-boron, i-niobium, njl. Isetyenziswe njenge-arhente yokunciphisa. Ukongezelela, i-ferrosilicon ingasetyenziselwa njenge-arhente yokunciphisa ukuveliswa kwe-ferromolybdenum, i-ferrovanadium kunye nezinye i-alloys zensimbi. I-silicon-chromium alloy kunye ne-silicon-manganese alloy ingasetyenziswa njengeejenti zokunciphisa ukucokisa i-carbon ferrochromium ephakathi kunye ne-medium-low-low carbon ferromanganese ngokulandelanayo.
Ngamafutshane, i-silicon inokuphucula kakhulu ukuqina kunye nokuqina kombane wentsimbi. Ke ngoko, ii-alloys ze-silicon kufuneka zisetyenziswe xa kunyibilikiswa intsimbi yesakhiwo, intsimbi yesixhobo, intsimbi yasentwasahlobo kunye nentsimbi ye-silicon yokuguqula; intsimbi jikelele iqulathe 0.15% -0.35% silicon, intsimbi yesakhiwo iqulathe 0.40% -1.75% lesilicon, kwaye isixhobo intsimbi iqulethe Silicon 0.30% -1.80%, spring steel iqulathe silicon 0.40% -2.80%, intsimbi stainless acid-resistant iqulethe silicon 3.40% -4.00%, insimbi ekwazi ukumelana nokushisa iqulethe i-silicon 1.00% -3.00%, i-silicon steel iqukethe i-silicon 2% - 3% okanye ngaphezulu. I-Manganese inokunciphisa i-brittleness yentsimbi, iphucule ukusebenza okushushu kwentsimbi, kunye nokwandisa amandla, ukuqina kunye nokumelana nokunxiba kwentsimbi.
