Ferrosilicon ndi ferroalloy wopangidwa ndi chitsulo ndi silicon.Ferrosilicon ndi aloyi yachitsulo-silicon yopangidwa ndi smelting coke, shavings zitsulo, ndi quartz (kapena silika) mu ng'anjo yamagetsi.Popeza silicon ndi okosijeni zimaphatikizidwa mosavuta kukhala silicon dioxide, ferrosilicon imagwiritsidwa ntchito ngati deoxidizer popanga zitsulo.Panthawi imodzimodziyo, chifukwa SiO2 imapanga kutentha kwakukulu, ndizopindulitsanso kuwonjezera kutentha kwachitsulo chosungunuka panthawi ya deoxidation.Nthawi yomweyo, ferrosilicon itha kugwiritsidwanso ntchito ngati chowonjezera cha alloying, ndipo imagwiritsidwa ntchito kwambiri muzitsulo zotsika za aloyi, masika zitsulo, zitsulo zokhala ndi chitsulo, chitsulo chosagwira kutentha ndi chitsulo chamagetsi cha silicon.Ferrosilicon nthawi zambiri amagwiritsidwa ntchito ngati chochepetsera pakupanga ferroalloy ndi makampani opanga mankhwala.
Ferroalloy yopangidwa ndi chitsulo ndi silicon (pogwiritsa ntchito silika, chitsulo, ndi coke monga zopangira, silicon yomwe yachepetsedwa pa kutentha kwakukulu kwa madigiri 1500-1800 imasungunuka muchitsulo chosungunuka kupanga ferrosilicon alloy).Ndilofunika kwambiri pamakampani osungunula.
Mafotokozedwe Akatundu
(1) Amagwiritsidwa ntchito ngati deoxidizer ndi alloying agents mumakampani azitsulo.Kuti mupeze mankhwala oyenerera komanso kutsimikizira kuti chitsulo chili chabwino, mu gawo lomaliza la chitsulocho chiyenera kukhala deoxidized.Kugwirizana kwa mankhwala pakati pa silicon ndi okosijeni ndi kwakukulu kwambiri, motero ferrosilicon ndi deoxi-dizer yolimba yomwe imagwiritsidwa ntchito popanga zitsulo komanso kufalitsa zitsulo.Onjezani kuchuluka kwa silicon muzitsulo, kumatha kusintha kwambiri mphamvu, kuuma komanso kukhazikika kwachitsulo.
(2) Amagwiritsidwa ntchito ngati nucleating agent ndi spheroidizing agent mumakampani achitsulo.Chitsulo chachitsulo ndi mtundu wa zipangizo zamakono zamakono zamafakitale,Ndizotsika mtengo kwambiri kuposa zitsulo, zosavuta kusungunula zoyenga, zokhala ndi ntchito yabwino kwambiri yoponyera komanso mphamvu zowonongeka ndi zabwino kuposa zitsulo.Makamaka nodular kuponyedwa chitsulo, ake makina katundu kapena pafupi ndi makina zimatha zitsulo.Onjezani kuchuluka kwa silicon mu chitsulo chosungunula kungalepheretse chitsulo kupanga, kulimbikitsa mpweya wa graphite ndi carbide spheroidizing.Chifukwa chake pakupanga chitsulo cha nodular, ferrosilicon ndi mtundu wazinthu zofunikira kwambiri (Thandizo lolekanitsa graphite) ndi spheroidizing agent.
