Beddelka birta samaynta calcium silicon Si40 Fe40 Ca10
Sharaxaada Alaabta
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 birta ee ka baxsan foornada, budada silikoon-calcium ama fiilada 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 sameynta garaafyada wareegsan ama wareegsan; wuxuu ka dhigayaa graphite ee birta cawl cawl si siman loo qaybiyay, waxay yaraynaysaa u janjeera caddaynta; oo kordhin kara silikoon iyo desulfurize , Hagaajinta tayada birta ee 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.
Xaalad jireed
ThQaybta e ca-si waa cawl khafiif ah oo u muuqday qaab hadhuudh cad. Buro,Badar iyo budo.
Xidhmada:
Shirkadeena waxay bixin kartaa noocyo kala duwan oo hadhuudh ah oo la cayimay iyadoo loo eegayo baahida isticmaale, kaas oo lagu baakadeeyay dhar balaastig ah iyo bac tan ah.
