I-alloy yokubini eyenziwe nge-silicon kunye ne-calcium yodidi lwe-ferroalloys. Amacandelo ayo aphambili yi-silicon kunye ne-calcium, kwaye iqulethe ukungcola okufana nentsimbi, i-aluminium, i-carbon, isulfure kunye ne-phosphorus ngamanani ahlukeneyo. Kwishishini lesinyithi kunye nentsimbi, isetyenziswe njenge-calcium additive, i-deoxidizer, i-desulfurizer kunye ne-denaturant ye-non-metallic inclusions. Isetyenziswa njenge-inoculant kunye ne-denaturant kwishishini lentsimbi.
Ukusetyenziswa:
Njenge-compound deoxidizer (i-deoxidization, i-desulphurization kunye ne-degassing) Isetyenziswe kwi-steelmaking, i-alloy smelting. Njenge-inoculant, ikwasetyenziswa kwimveliso yokugalela.
Isimo somzimba:
Icandelo le-ca-si lingwevu elikhanyayo nelivele linemilo ecacileyo yeenkozo. Intlama, ingqolowa kunye nomgubo.
Umqulu:
Inkampani yethu inokubonelela ngeendlela ezahlukeneyo zokuziinkozo ngokweemfuno zabasebenzisi, ezipakishwe ngelaphu leplastiki kunye nebhegi yeetoni.

Okunye ukungcola kuchazwa ngokweenjongo ezahlukeneyo. Ukongezelela, ngesiseko se-silicon-calcium alloys, ezinye izinto zongezwa ukwenza i-ternary okanye i-multi-element composite alloys. Ezinje ngeSi-Ca-Al; Si-Ca-Mn; I-Si-Ca-Ba, njl., isetyenziswe njenge-deoxidizer, i-desulfurizer, i-agent ye-denitrification kunye ne-alloying agent kwi-iron kunye ne-metallurgy yensimbi.
Ekubeni i-calcium inobudlelwane obuqinileyo kunye ne-oksijeni, isulfure, i-hydrogen, i-nitrogen kunye nekhabhoni kwintsimbi etyhidiweyo, ii-alloys ze-silicon-calcium zisetyenziselwa i-deoxidation, i-degassing kunye nokulungiswa kwesulfure kwintsimbi etyhidiweyo. Isilicon yeCalcium ivelisa isiphumo esinamandla se-exothermic xa ifakwe kwintsimbi etyhidiweyo. I-calcium ijika ibe ngumphunga wekhalsiyam kwintsimbi etyhidiweyo, enefuthe elivuselelayo kwintsimbi etyhidiweyo kwaye iluncedo ekujuleni kwezinto ezifakwayo ezingezizo ezentsimbi. Emva kokuba i-silicon-calcium alloy i-deoxidized, i-non-metallic inclusions kunye neengqungquthela ezinkulu kunye nokulula ukudada ziveliswa, kwaye imilo kunye neepropati ze-non-metallic inclusions nazo zitshintshiwe. Ke ngoko, i-silicon-calcium alloy isetyenziselwa ukuvelisa intsimbi ecocekileyo, insimbi ephezulu eneoksijini ephantsi kunye nomxholo wesulfure, kunye nentsimbi yokusebenza ekhethekileyo eneoksijini ephantsi kakhulu kunye nomxholo wesulfure. Ukongezwa kwe-silicon-calcium alloy kunokuphelisa i-nodulation yentsimbi kunye ne-aluminium njenge-deoxidizer yokugqibela kwi-ladle nozzle, kunye nokuvala umlomo we-tundish yokuphosa okuqhubekayo | ukwenza intsimbi. Kwiteknoloji yokucoca ngaphandle kwesithando somlilo, i-silicon-calcium powder okanye i-core wire isetyenziselwa i-deoxidation kunye ne-desulfurization ukunciphisa umxholo we-oksijini kunye nesulfure kwintsimbi ukuya kwinqanaba eliphantsi kakhulu; inokulawula kwakhona uhlobo lwe-sulfide kwintsimbi kunye nokuphucula izinga lokusetyenziswa kwe-calcium. Ekuveliseni isinyithi esityhidiweyo, ngaphezu kwe-deoxidation kunye nokuhlanjululwa, i-silicon-calcium alloy nayo idlala indima ye-inoculating, eyanceda ukwenza i-graphite ecocekileyo okanye eyi-spherical; yenza i-graphite kwintsimbi yentsimbi engwevu isasazwe ngokulinganayo, inciphisa ukuthambekela kokuba mhlophe; kwaye inokunyusa i-silicon kunye ne-desulfurize, Ukuphucula umgangatho wentsimbi.
