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, intsimbi 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.Kwimveliso yentsimbi etyhidiweyo, 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.
