Calcium Silicon Alloy ndi alloy binary ya silicon ndi calcium, zigawo zake zazikulu ndi silicon ndi calcium, komanso zimakhala ndi zitsulo zosiyanasiyana, aluminiyamu, carbon, sulfure ndi phosphorous ndi zitsulo zina.
Chifukwa cha kuyanjana kwakukulu pakati pa kashiamu ndi mpweya, sulfure, haidrojeni, nayitrogeni ndi mpweya muzitsulo zamadzimadzi, Calcium Silicon Alloy amagwiritsidwa ntchito makamaka pochotsa, degassing ndi kukonza sulfure muzitsulo zamadzimadzi, calcium silicon pambuyo powonjezera zitsulo zamadzimadzi zimapanga mphamvu yamphamvu ya exothermic, kashiamu amakhala kashiamu nthunzi mu madzi zitsulo, oyambitsa zotsatira pa madzi zitsulo, amene amathandiza kuti zoyandama inclusions sanali zitsulo. Pambuyo pa deoxidation, silicon calcium alloy imapanga zosakanikirana zopanda zitsulo zomwe zimakhala ndi tinthu tating'onoting'ono komanso zosavuta kuyandama, komanso zimasintha mawonekedwe ndi katundu wazinthu zopanda zitsulo. Choncho, silicon calcium alloy imagwiritsidwa ntchito popanga chitsulo choyera, chitsulo chamtengo wapatali chokhala ndi mpweya wochepa ndi sulfure, ndi chitsulo chapadera chokhala ndi mpweya wochepa kwambiri ndi sulfure.
