Ferrosilicon waa ferroalloy ka kooban bir iyo silikoon.Ferrosilicon waa daawaha birta-silikoon ee lagu sameeyo dhalaalinta kookaha, xiirashada birta, iyo quartz (ama silica) foornada korontada.Maadaama silikoon iyo oksijiin si fudud loogu daro silikon dioxide, ferrosilicon waxaa badanaa loo isticmaalaa deoxidizer-ka samaynta birta.Isla mar ahaantaana, sababtoo ah SiO2 waxay abuurtaa kulayl badan, waxay sidoo kale faa'iido u leedahay in la kordhiyo heerkulka birta dhalaalaysa inta lagu jiro deoxidation.Isla mar ahaantaana, ferrosilicon sidoo kale waxaa loo isticmaali karaa sidii wax lagu daro walxaha alloying, waxaana si weyn loogu isticmaalaa birta qaab dhismeedka alloy hooseeya, birta guga, birta sida, birta kulaylka u adkeysata iyo birta silikon koronto.Ferrosilicon waxaa inta badan loo isticmaalaa sida wakiilka dhimaya wax soo saarka ferroalloy iyo warshadaha kiimikada.
Ferroalloy oo ka kooban bir iyo silikoon (iyadoo la isticmaalayo silica, birta, iyo kookaha sida alaabta ceeriin, silikoon lagu dhimay heerkul sare oo ah 1500-1800 darajo ayaa lagu dhalaaley birta dhalaalaysa si ay u sameeyaan daawaha ferrosilicon).Waa noocyo kala duwan oo daawaha ah oo muhiim u ah warshadaha dhalaalidda.
Sharaxaada badeecada
(1) Loo isticmaalo sida deoxidizer iyo walxaha daawaha ee warshadaha birta.Si loo helo ka kooban kiimiko tayo leh oo loo dammaanad qaado tayada birta, marxaladda ugu dambeysa ee birta waa in la nadiifiyaa.Xidhiidhka kiimikaad ee u dhexeeya silikoon iyo ogsijiin waa mid aad u weyn, sidaas darteed ferrosilicon waa deoxidizer xooggan oo loo isticmaalo wasakhaynta iyo deoxidation baahinta birta samaynta.Ku dar qadar gaar ah oo silikoon ah birta, waxay si weyn u hagaajin kartaa xoogga, qallafsanaanta iyo dabacsanaanta birta.
(2) Loo isticmaalo sidii wakiilka nuclei-ka iyo wakiilka spheroidizing ee warshadaha birta.Birta birta ah waa nooc ka mid ah qalabka birta warshadaha casriga ah ee muhiimka ah, aad bay uga jaban tahay birta, si fudud ayaa loo dhalaaliyaa sifaynta, oo leh waxqabadka shubka wanaagsan iyo awoodda seismic aad ayay uga fiican tahay birta.Khaasatan birta kabka nodular, sifadeeda makaanikada ee ku taal ama u dhow sifooyinka makaanikada birta.Ku dar qadar gaar ah oo silikoon ah oo ku jira birta shubka ah waxay ka hortagi kartaa sameynta birta, waxay kor u qaadeysaa roobabka garaafka iyo karbide spheroidizing.Markaa wax soo saarka birta nodular, ferrosilicon waa nooc ka mid ah tallaalada muhiimka ah (Ka caawi kala soocida graphite) iyo wakiilka spheroidizing.
