Aloyi ya binary yopangidwa ndi silicon ndi calcium ndi ya gulu la ferroalloys.Zigawo zake zazikulu ndi silicon ndi calcium, komanso zimakhala ndi zonyansa monga chitsulo, aluminiyamu, carbon, sulfure ndi phosphorous mosiyanasiyana.M'makampani achitsulo ndi zitsulo, amagwiritsidwa ntchito ngati chowonjezera cha calcium, deoxidizer, desulfurizer ndi denaturant kwa osakhala zitsulo.Amagwiritsidwa ntchito ngati inoculant komanso denaturant mumakampani opanga chitsulo.
Kagwiritsidwe:
Monga pawiri deoxidizer (deoxidization, desulphurization ndi degassing) Amagwiritsidwa ntchito popanga zitsulo, alloy smelting.Monga inoculant, amagwiritsidwanso ntchito popanga kupanga.
Thupi:
Gawo la ca-si ndi lotuwa mopepuka lomwe limawoneka ndi mawonekedwe owoneka bwino ambewu.Lump, Mbewu ndi ufa.
Phukusi:
kampani yathu ikhoza kupereka mawonekedwe osiyanasiyana a tirigu malinga ndi zofuna za wogwiritsa ntchito, zomwe zimadzaza ndi nsalu zapulasitiki ndi thumba la tani.

Zonyansa zina zimatchulidwa malinga ndi zolinga zosiyanasiyana.Kuphatikiza apo, pamaziko a silicon-calcium alloys, zinthu zina zimawonjezeredwa kuti zipange ternary kapena multi-element composite alloys.Monga Si-Ca-Al;Si-Ca-Mn;Si-Ca-Ba, etc., ntchito monga deoxidizer, desulfurizer, denitrification wothandizila ndi alloying wothandizila chitsulo ndi zitsulo zitsulo.
Popeza calcium imakhala yogwirizana kwambiri ndi okosijeni, sulfure, haidrojeni, nayitrogeni ndi kaboni muzitsulo zosungunuka, ma alloys a silicon-calcium amagwiritsidwa ntchito makamaka pochotsa, kutulutsa mpweya ndi kukonza sulfure muzitsulo zosungunuka.Silicon ya calcium imatulutsa mphamvu yotulutsa mphamvu ikawonjezeredwa kuchitsulo chosungunuka.Calcium imasanduka nthunzi ya kashiamu muzitsulo zosungunuka, zomwe zimakhala ndi mphamvu pazitsulo zosungunuka ndipo zimakhala zopindulitsa pakuyandama kwa zinthu zopanda zitsulo.Pambuyo pa alloy silicon-calcium alloy deoxidized, non-metal inclusions ndi tinthu tating'onoting'ono tating'onoting'ono tomwe timayandama timapangidwa, ndipo mawonekedwe ndi mawonekedwe azinthu zopanda zitsulo zimasinthidwanso.Choncho, silicon-calcium alloy imagwiritsidwa ntchito popanga chitsulo choyera, chitsulo chapamwamba chokhala ndi mpweya wochepa wa sulfure ndi sulfure, ndi chitsulo chogwira ntchito chapadera chokhala ndi mpweya wochepa kwambiri ndi sulfure.Kuwonjezera silicon-kashiamu aloyi akhoza kuthetsa nodulation wa zitsulo ndi aluminiyamu monga deoxidizer komaliza pa nozzle ladle, ndi clogging wa nozzle wa tundish wa kuponyera mosalekeza |kupanga zitsulo.Muukadaulo woyenga kunja kwa ng'anjo yachitsulo, ufa wa silicon-calcium kapena waya wapakati umagwiritsidwa ntchito pochotsa mpweya ndi sulfurization kuti achepetse zomwe zili ndi okosijeni ndi sulfure muzitsulo mpaka kutsika kwambiri;imathanso kuwongolera mawonekedwe a sulfide muzitsulo ndikuwongolera kuchuluka kwa magwiritsidwe a calcium.Popanga chitsulo chosungunula, kuwonjezera pa deoxidation ndi kuyeretsa, silicon-calcium alloy imagwiranso ntchito yotsekemera, yomwe imathandiza kupanga graphite yabwino kapena yozungulira;amapanga graphite mu imvi kuponyedwa chitsulo wogawana anagawira, amachepetsa whitening chizolowezi;ndipo amatha kuonjezera silicon ndi desulfurize, Kupititsa patsogolo khalidwe lachitsulo.
