Ferro silicon yog ib hom ferro alloys uas yog kev sib xyaw ntawm silicon thiab hlau. Qhov piv ntawm ob yam tshuaj sib xyaw ua ke sib txawv, nrog rau qhov sib piv ntawm silicon nyob qhov twg ntawm 15% thiab 90%. Ferro Silicon 65 yog siv coke, steel chips thiab quartz (los yog silica) ua raw cov ntaub ntawv, tom qab kub kub txo ntawm 1500-1800 degrees, silicon melts nyob rau hauv molten hlau los tsim ferro silicon.
Ferro silicon los ntawm Zhenan ferroalloy Hoobkas yog ferrosilicon alloy tsim ntawm silicon thiab hlau nyob rau hauv ib qho kev faib ua feem thiab yog tsuas yog siv rau steel smelting thiab hlau magnesium smelting.
