1. Metallic silicon imatanthawuza zinthu za silicon zenizeni zomwe zili ndi silikoni wamkulu kuposa kapena wofanana ndi 98.5%. Zinthu zitatu zonyansa zachitsulo, zotayidwa, ndi calcium (zokonzedwa bwino) zimagawidwa m'magulu, monga 553, 441, 331, 2202, ndi zina. Pakati pawo, 553 Metallic Silicon imayimira kuti chitsulo cha zitsulo zosiyanasiyana ndi zosakwana kapena zofanana ndi 0.5%, zotayidwa ndi zochepa kapena zofanana ndi 0.5%, ndi calcium yocheperapo kapena yofanana ndi 0.3%; 331 Metallic Silicon imayimira kuti chitsulo ndi chocheperapo kapena chofanana ndi 0.3%, zotayidwa ndizochepera kapena zofanana ndi 0.3%, ndipo calcium yocheperako kapena yofanana ndi 0.3%. Zocheperapo kapena zofanana ndi 0.1%, ndi zina zotero. Pazifukwa zachikhalidwe, 2202 chitsulo silikoni amafupikitsidwa ngati 220, kutanthauza kuti calcium ndi yocheperapo kapena yofanana ndi 0.02%.
Kugwiritsa ntchito kwakukulu kwa silicon yamafakitale: Silicon yamafakitale imagwiritsidwa ntchito ngati chowonjezera pazitsulo zopanda chitsulo. Silicon yamakampani imagwiritsidwanso ntchito ngati alloying alloying silicon zitsulo zokhala ndi zofunika kwambiri komanso ngati deoxidizer posungunula chitsulo chapadera ndi ma aloyi opanda chitsulo. Pambuyo pa njira zingapo, silicon yamakampani imatha kukokedwa mu silicon imodzi ya crystal kuti igwiritsidwe ntchito pamagetsi amagetsi komanso m'makampani opanga mankhwala a silicon, etc. Choncho, amadziwika kuti zitsulo zamatsenga ndipo ali ndi ntchito zosiyanasiyana.
2. Ferrosilicon imapangidwa kuchokera ku coke, zitsulo zachitsulo, quartz (kapena silika) monga zopangira ndipo zimasungunuka mu ng'anjo ya arc yomwe ili pansi pa madzi. Silikoni ndi okosijeni zimalumikizana mosavuta kupanga silika. Choncho, ferrosilicon nthawi zambiri amagwiritsidwa ntchito ngati deoxidizer pakupanga zitsulo. Pa nthawi yomweyi, chifukwa SiO2 imatulutsa kutentha kwakukulu ikapangidwa, ndizopindulitsanso kuwonjezera kutentha kwachitsulo chosungunuka pamene deoxidizing.
Ferrosilicon imagwiritsidwa ntchito ngati alloying element. Amagwiritsidwa ntchito kwambiri muzitsulo zotsika za alloy structural zitsulo, zitsulo zomangika, zitsulo zamasika, zitsulo zokhala ndi zitsulo, zitsulo zosagwira kutentha ndi chitsulo cha silicon. Ferrosilicon nthawi zambiri amagwiritsidwa ntchito ngati chochepetsera m'mafakitale a ferroalloy ndi mankhwala. Zomwe zili mu silicon zimafika 95% -99%. Silicon yoyera imagwiritsidwa ntchito kwambiri popanga silikoni imodzi ya kristalo kapena kukonza ma alloys achitsulo omwe si achitsulo.
Kagwiritsidwe: Ferrosilicon chimagwiritsidwa ntchito mu makampani zitsulo, mafakitale foundry ndi mafakitale ena.
Ferrosilicon ndi deoxidizer yofunika kwambiri pamakampani opanga zitsulo. Popanga zitsulo, ferrosilicon imagwiritsidwa ntchito potulutsa mpweya komanso kutulutsa mpweya. Njerwa yachitsulo imagwiritsidwanso ntchito ngati alloying agent popanga zitsulo. Kuonjezera kuchuluka kwa silicon kuchitsulo kumatha kupititsa patsogolo mphamvu, kuuma ndi kusungunuka kwachitsulo, kuonjezera mphamvu ya maginito yachitsulo, ndi kuchepetsa kuwonongeka kwa chitsulo cha transformer. Chitsulo chonse chili ndi silicon 0.15% -0.35%, chitsulo chokhazikika chili ndi 0.40% -1.75% silicon, chitsulo chachitsulo chili ndi 0.30% -1.80% silicon, chitsulo cha masika chili ndi silicon 0.40% -2.80%, chitsulo chosapanga dzimbiri chokhala ndi silicon 3.40% ~ 4.00%, chitsulo chosagwira kutentha chimakhala ndi silicon 1.00% ~ 3.00%, chitsulo cha silicon chimakhala ndi silicon 2% ~ 3% kapena kupitilira apo. M'makampani opanga zitsulo, tani iliyonse yachitsulo imadya pafupifupi 3 mpaka 5kg ya 75% ferrosilicon.
