I-alloy kanambambili eyakhiwe nge-silicon ne-calcium ingeyesigaba sama-ferroalloys. Izingxenye zayo eziyinhloko ziyi-silicon ne-calcium, futhi iqukethe nokungcola okunjengensimbi, i-aluminium, i-carbon, isulfure ne-phosphorus ngamanani ahlukahlukene. Embonini yensimbi nensimbi, isetshenziswa njengesengezo se-calcium, i-deoxidizer, i-desulfurizer kanye ne-denaturant ye-non-metallic inclusions. Isetshenziswa njenge-inoculant kanye ne-denaturant embonini ye-cast iron.
Ukusetshenziswa:
Njenge-compound deoxidizer (i-deoxidization, desulphurization and degassing) Isetshenziswa ekwenzeni insimbi, ukuncibilikisa ingxubevange. Njenge-inoculant, ibuye isetshenziswe ekukhiqizeni ukukhiqiza.
Isimo somzimba:
Ingxenye ye-ca-si impunga ngokukhanyayo evele inomumo wokusanhlamvu osobala. Isigaxa, okusanhlamvu kanye nempushana.
Iphakheji:
inkampani yethu inganikela ngezimo ezihlukahlukene ezishiwo okusanhlamvu ngokuvumelana nezidingo zabasebenzisi, ezipakishwe ngendwangu yepulasitiki kanye nesikhwama sethani.

Okunye ukungcola kushiwo ngokwezinjongo ezahlukene. Ngaphezu kwalokho, ngesisekelo sama-alloys e-silicon-calcium, ezinye izakhi zengezwa ukuze zenze ama-alloys e-ternary noma ama-multi-element composite. NjengeSi-Ca-Al; Si-Ca-Mn; I-Si-Ca-Ba, njll., isetshenziswa njenge-deoxidizer, i-desulfurizer, i-ejenti ye-denitrification kanye ne-alloying ejenti kunsimbi nensimbi.
Njengoba i-calcium inobungane obuqinile ne-oksijeni, isulfure, i-hydrogen, i-nitrogen ne-carbon ensimbi encibilikisiwe, ama-alloys e-silicon-calcium asetshenziselwa ngokuyinhloko ukuqeda amandla, ukukhipha umoya kanye nokulungiswa kwesibabule ensimbi encibilikisiwe. I-calcium silicon ikhiqiza umphumela oqinile we-exothermic uma yengezwe ensimbi encibilikisiwe. I-calcium iphenduka ibe umhwamuko we-calcium ensimbi encibilikisiwe, enomthelela onyakazayo ensimbi encibilikisiwe futhi inenzuzo ekuntanteni kokuhlanganisa okungeyona insimbi. Ngemuva kokuthi i-silicon-calcium alloy i-deoxidized, ukufakwa okungezona okwensimbi okunezinhlayiya ezinkulu futhi kulula ukuntanta kuyakhiqizwa, futhi ukwakheka kanye nezakhiwo ze-non-metallic inclusions nazo ziyashintshwa. Ngakho-ke, i-silicon-calcium alloy isetshenziselwa ukukhiqiza insimbi ehlanzekile, insimbi yekhwalithi ephezulu enomoya-mpilo ophansi nesibabule, kanye nensimbi yokusebenza okukhethekile enomoya-mpilo ophansi kakhulu nesibabule. Ukwengezwa kwe-silicon-calcium alloy kungaqeda ukugoqa kwensimbi nge-aluminium njenge-deoxidizer yokugcina emlonyeni we-ladle, kanye nokuvala umlomo wombhobho we-tundish yokusakazwa okuqhubekayo | ukwenza insimbi. Kubuchwepheshe bokucwenga ngaphandle kwesithando somlilo sensimbi, i-silicon-calcium powder noma ucingo oluyisisekelo lusetshenziselwa i-deoxidation kanye ne-desulfurization ukunciphisa okuqukethwe komoya-mpilo nesibabule ensimbi kuya ezingeni eliphansi kakhulu; ingakwazi futhi ukulawula uhlobo lwe-sulfide ensimbi futhi ithuthukise izinga lokusebenzisa i-calcium. Ekukhiqizeni i-cast iron, ngaphezu kwe-deoxidation nokuhlanzwa, i-silicon-calcium alloy nayo idlala indima ye-inoculating, esiza ukwakha i-graphite ehlanjululwe kahle noma eyindilinga; yenza i-graphite ngensimbi empunga isatshalaliswe ngokulinganayo, inciphisa ukuthambekela kokuba mhlophe; futhi ingakhuphula i-silicon kanye ne-desulfurize, Thuthukisa ikhwalithi ye-cast iron.
