Daawaha binary ee ka kooban silikoon iyo kalsiyum ayaa iska leh qaybta ferroalloys.Qaybaha ugu muhiimsan ee ay ka kooban tahay waa Silicon iyo calcium, sidoo kale waxa ku jira wasakh sida birta, aluminium, kaarboon, baaruud iyo fosfooraska oo xaddigeedu kala duwan yahay.Warshadaha birta iyo birta, waxa loo isticmaalaa kaalshiyam wax lagu daro, deoxidizer, desulfurizer iyo denaturant si loogu daro kuwa aan birta ahayn.Waxa loo istcimaalaa sidii daaweeye iyo denaturant warshadaha kabka birta.
Isticmaalka:
Sida deoxidizer ka samaysan (deoxidization, desulphurization and Degassing) Loo isticmaalo samaynta birta, dhalaalinta daawaha.Sida tallaalka, sidoo kale loo isticmaalo wax soo saarka kabka.
Xaaladda jireed:
Qaybta ca-si waa cawl khafiif ah oo u muuqday qaab hadhuudh cad.Buro,Badar iyo budo.
Xidhmada:
Shirkadeena waxay ku siin kartaa noocyo kala duwan oo hadhuudh ah oo la cayimay iyadoo loo eegayo baahida isticmaale, kaas oo lagu baakadeeyay dhar balaastig ah iyo bac ton ah.

Wasakhyada kale waxaa lagu qeexaa ujeedooyin kala duwan.Intaa waxaa dheer, iyada oo lagu saleynayo alwaaxyada silikoon-calcium, walxo kale ayaa lagu daraa si ay u sameeyaan ternary ama walxo badan oo isku dhafan.Sida Si-Ca-Al;Si-Ca-Mn;Si-Ca-Ba, iwm, loo isticmaalo sida deoxidizer, desulfurizer, wakiilka denitrification iyo wakiilka alloying ee birta iyo birta birta.
Maaddaama kalsiyumku leeyahay xidhiidh xooggan oo leh ogsijiin, baaruud, hydrogen, nitrogen iyo kaarboon ku jira birta dhalaalaysa, silikoon-calcium alloys ayaa inta badan loo isticmaalaa deoxidation, soo saarista iyo hagaajinta baaruudda ee birta dhalaalaysa.Silicon Calcium waxay soo saartaa saameyn xoog leh marka lagu daro birta dhalaalaysa.Kaalshiyamku waxa uu isu beddelaa uumiga kaalshiyamka ee birta dhalaalaysa, kaas oo saamayn walaaqaya ku leh birta dhalaalaysa oo faa'iido u leh sabbaynta waxyaabaha aan birta ahayn.Ka dib markii daawaha silikoon-calcium la deoxidized, ka mid ah non-metallic ka kooban qaybo waaweyn oo ay fududahay in la sabeeyo ayaa la soo saaray, iyo qaabka iyo sifooyinka ka mid ah non-birta ah ayaa sidoo kale la bedelay.Sidaa darteed, silikoon-calcium alloy waxaa loo isticmaalaa in lagu soo saaro bir nadiif ah, bir tayo sare leh oo leh oksijiin iyo baaruud hoose, iyo birta waxqabadka gaarka ah oo leh oksijiin iyo baaruud aad u hooseeya.Ku darida silikoon-calcium alloy waxay baabi'in kartaa nuujinta birta leh aluminium sida deoxidizer kama dambaysta ah ee sanka birta, iyo xiritaanka biibiile ee tundish ee shubista joogtada ah |birta samaynta.Tiknoolajiyada sifaynta ee ka baxsan foornada birta, budada silikoon-calcium ama siligga asaasiga ah ayaa loo isticmaalaa deoxidation iyo desulfurization si loo yareeyo nuxurka oksijiinta iyo baaruudka ee birta ilaa heer aad u hooseeya;waxay sidoo kale xakameyn kartaa qaabka sulfide ee birta waxayna hagaajin kartaa heerka isticmaalka kalsiyumka.Soo saarista birta birta ah, marka lagu daro deoxidation iyo nadiifinta, silikoon-calcium alloy sidoo kale wuxuu ka ciyaaraa doorka tallaalka, kaas oo gacan ka geysanaya samaynta garaafyada qaabaysan ama wareegsan;wuxuu ka dhigayaa graphite ee birta cawl cawl si siman loo qaybiyay, waxay yaraynaysaa u janjeersiga caddaynta;oo kordhin kara silikoon iyo desulfurize , Hagaajinta tayada birta ee birta.
