FerroChrome
Ukubwa:1-100 mm
Ferrochrome (FeCr) ni aloi ya chromium na chuma iliyo na kati ya 50% na 70% ya chromium. Zaidi ya 80% ya ferrochrome duniani hutumiwa katika uzalishaji wa chuma cha pua.Kulingana na maudhui ya kaboni, inaweza kugawanywa katika:Ferororomi ya kaboni ya juu/HCFeCr(C:4%-8%),ferrochrome ya kaboni ya wastani/MCFeCr(C:1%-4%),ferrochrome ya kaboni ya Chini/LCFeCr(C:0.25) %-0.5%),Frochrome ndogo ya kaboni/MCFeCr:(C:0.03 0.15%).Uchina kwa ajili ya kuongeza sehemu ya uzalishaji wa feroromu duniani.

Maombi:
①Hutumika katika utengenezaji wa chuma cha pua,Chuma cha pua hutegemea chromium kwa kuonekana kwake na upinzani dhidi ya kutu.
②Kama kiongezeo kikuu cha aloi katika utengenezaji wa chuma
③Kama nyongeza ya lazima katika mchakato wa kuyeyusha chuma cha kaboni ya chini
