Thepa le melemo ea ferrosilicon

Binary alloy e entsoeng ka silicon le calcium ke ea sehlopha sa ferroalloys. Likarolo tsa eona tse ka sehloohong ke silicon le calcium, hape e na le litšila tse kang tšepe, aluminium, carbon, sulfur le phosphorus ka bongata bo sa tšoaneng. Ka indasteri ea tšepe le tšepe, e sebelisoa e le motsoako oa calcium, deoxidizer, desulfurizer le denaturant bakeng sa li-inclusions tse se nang tšepe. E sebelisoa e le ente le denaturant indastering ea tšepe ea tšepe. Motheong oa silicon-calcium alloy, likarolo tse ling li eketsoa ho etsa motsoako oa ternary kapa oa multi-element composite alloy. Tse kang Si-Ca-Al; Si-Ca-Mn; Si-Ca-Ba, joalo-joalo, e sebelisoa e le deoxidizer, desulfurizer, denitrification agent le alloying agent ka tšepe le tšepe ea tšepe.
