(1) Amagwiritsidwa ntchito ngati deoxidizer ndi alloying alloying mumakampani opanga zitsulo. Kuti mupeze zitsulo zokhala ndi mankhwala oyenerera komanso kuonetsetsa kuti zitsulo zili bwino, deoxidation iyenera kuchitidwa pamapeto omaliza a zitsulo. Kugwirizana kwamankhwala pakati pa silicon ndi okosijeni ndi kwakukulu kwambiri, kotero ferrosilicon ndi deoxidizer yofunika kwambiri pamakampani opanga zitsulo. Popanga zitsulo, kupatulapo zitsulo zina zowira, pafupifupi mitundu yonse yazitsulo imagwiritsa ntchito ferrosilicon ngati deoxidizer yamphamvu ya mpweya wotulutsa mpweya komanso kutulutsa mpweya. Kuonjezera kuchuluka kwa silicon kuchitsulo kumatha kupititsa patsogolo mphamvu, kulimba komanso kukhazikika kwachitsulo. Choncho, amagwiritsidwa ntchito kwambiri posungunula zitsulo zamagulu (zokhala ndi siO. 40% ~ 1.75%) ndi zitsulo zachitsulo (zokhala ndi siO. 30%). ~ 1.8%), zitsulo zamasika (zokhala ndi Si O. 40% ~ 2.8%) ndi mitundu ina yazitsulo, kuchuluka kwa ferrosilicon kuyenera kuwonjezeredwa ngati alloying alloying. Silicon ilinso ndi mawonekedwe a kukana kwakukulu kwapadera, kusayenda bwino kwamafuta ndi maginito amphamvu. Chitsulo chimakhala ndi silicon yambiri, yomwe imatha kupititsa patsogolo mphamvu ya maginito yachitsulo, kuchepetsa kutaya kwa hysteresis, ndi kuchepetsa kuwonongeka kwa eddy panopa. Choncho, ferrosilicon amagwiritsidwanso ntchito ngati alloying wothandizira pamene smelting pakachitsulo zitsulo, monga otsika pakachitsulo zitsulo kwa Motors (muli Si O. 80% kuti 2.80%) ndi pakachitsulo zitsulo kwa thiransifoma (muli Si 2.81% kuti 4.8%). ntchito.
Kuonjezera apo, m'makampani opanga zitsulo, ufa wa ferrosilicon ukhoza kutulutsa kutentha kwakukulu pamene utenthedwa pa kutentha kwakukulu ndipo nthawi zambiri umagwiritsidwa ntchito ngati chotenthetsera chazitsulo zopangira zitsulo zopangira zitsulo kuti zikhale bwino komanso ziwonjezeke.
(2) Amagwiritsidwa ntchito ngati inoculant ndi spheroidizing wothandizira pamakampani opanga chitsulo. Cast iron ndi chinthu chofunikira kwambiri pamakampani amakono. Ndiwotsika mtengo kuposa chitsulo, yosavuta kusungunuka ndi kusungunula, imakhala ndi zinthu zabwino kwambiri zoponyera komanso kukana zivomezi kuposa chitsulo. Makamaka ductile iron, mawotchi ake amafika kapena ali pafupi ndi chitsulo. ntchito. Kuonjezera kuchuluka kwa ferrosilicon kuponya chitsulo kungalepheretse mapangidwe a carbides muchitsulo ndikulimbikitsa mpweya ndi spheroidization wa graphite. Choncho, popanga chitsulo cha ductile, ferrosilicon ndi inoculant yofunikira (yothandiza kutulutsa graphite) ndi spheroidizing agent. .
(3) Amagwiritsidwa ntchito ngati chochepetsera pakupanga ferroalloy. Sikuti kuyanjana kwamankhwala pakati pa silicon ndi okosijeni kumakhala kokwera kwambiri, koma kaboni wa high-silicon ferrosilicon ndiotsika kwambiri. Chifukwa chake, high-silicon ferrosilicon (kapena silicon alloy) ndi chochepetsera chomwe chimagwiritsidwa ntchito kwambiri pamakampani a ferroalloy popanga ma ferroalloys a carbon low.
