75 Ferrosilicon Covyog cov khoom siv metallurgical uas muaj cov ntsiab lus silicon ntawm 75%. Nws yog ib qho khoom siv raw khoom siv rau steelmaking. Cov khoom siv raw rau kev tsim 75 ferrosilicon feem ntau yog coke, steel scraps, thiab quartz pob zeb, uas yog rhuab thiab smelted nyob rau hauv lub cub hluav taws xob.
