Kuphatikiza pa kugwiritsidwa ntchito popanga chitsulo, ferrosilicon imagwiritsidwanso ntchito ngati deoxidizer posungunula chitsulo cha magnesium. Kupanga zitsulo ndi njira yomwe chitsulo chosungunula chimaphwanyidwa ndikuchotsa zonyansa monga phosphorous ndi sulfure powombera mpweya kapena kuwonjezera ma oxygen. Panthawi yopanga zitsulo kuchokera ku chitsulo cha nkhumba, mpweya wa okosijeni muzitsulo zosungunula umawonjezeka pang'onopang'ono, ndipo kawirikawiri umayimiridwa ndi FeO ilipo muzitsulo zosungunuka. Ngati mpweya wochuluka wotsalira muzitsulo sunachotsedwe ku silicon-manganese alloy, sungathe kuponyedwa mu billet yachitsulo yoyenerera, ndipo chitsulo chokhala ndi makina abwino sichingapezeke.
Kuti muchite izi, m'pofunika kuwonjezera zinthu zina zomwe zimakhala ndi mphamvu yomangirira kwambiri ndi okosijeni kuposa chitsulo, ndipo ma oxides ake ndi osavuta kuchotsa ku chitsulo chosungunula mu slag. Malinga ndi mphamvu yomangirira ya zinthu zosiyanasiyana muchitsulo chosungunuka kupita ku okosijeni, dongosolo lochokera ku chofooka kupita ku lamphamvu lili motere: chromium, manganese, carbon, silicon, vanadium, titaniyamu, boron, aluminium, zirconium, ndi calcium. Choncho, zitsulo zachitsulo zopangidwa ndi silicon, manganese, aluminiyamu, ndi calcium zimagwiritsidwa ntchito popanga zitsulo.
Amagwiritsidwa ntchito ngati alloying agent. Alloying zinthu sangathe kuchepetsa zonyansa zili zitsulo, komanso kusintha mankhwala zikuchokera zitsulo. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo silicon, manganese, chromium, molybdenum, vanadium, titaniyamu, tungsten, cobalt, boron, niobium, ndi zina zotero. Amagwiritsidwa ntchito ngati kuchepetsa. Komanso, ferrosilicon angagwiritsidwe ntchito ngati kuchepetsa wothandizila kupanga ferromolybdenum, ferrovanadium ndi ma aloyi ena chitsulo. Silicon-chromium alloy ndi silicon-manganese alloy angagwiritsidwe ntchito ngati kuchepetsa othandizira kuyenga sing'anga-otsika mpweya ferrochromium ndi sing'anga-otsika carbon ferromanganese motero.
Mwachidule, silicon amatha kusintha kwambiri elasticity ndi maginito permeability zitsulo. Chifukwa chake, ma aloyi a silicon ayenera kugwiritsidwa ntchito posungunula zitsulo zamapangidwe, chitsulo chachitsulo, chitsulo cha masika ndi chitsulo cha silicon kwa thiransifoma; zitsulo ambiri lili pakachitsulo 0.15% -0.35% pakachitsulo, structural zitsulo lili 0.40% -1.75% pakachitsulo, ndi chitsulo zitsulo lili Silicon 0.30% -1.80%, masika zitsulo lili pakachitsulo 0.40% -2.80%, zosapanga dzimbiri asidi zosagwira zitsulo lili pakachitsulo 3.40% -4.00%, chitsulo chosagwira kutentha chimakhala ndi silicon 1.00% -3.00%, chitsulo cha silicon chili ndi silicon 2% - 3% kapena kuposa. Manganese amatha kuchepetsa kuphulika kwachitsulo, kupititsa patsogolo ntchito yotentha yachitsulo, ndikuwonjezera mphamvu, kuuma ndi kuvala kukana kwachitsulo.
