Identifikacija kvalitete praha fero kroma s visokim udjelom ugljika

Ferokrom s visokim udjelom ugljika kao veliku kupnju proizvoda, vrlo je važno identificirati njegovu dobro ili loše. Za proizvodnju ferokroma s visokim udjelom ugljika potrebne su sirovine za ferolegure kromova ruda, koks i silicij, kako bi se prilagodila vrsta troske, potrebno je dodati određenu količinu bijelog pepela ili dolomita, proizvođači ferokroma s visokim udjelom ugljika za sirovine imaju vrlo visoke zahtjeve, zahtijevaju visoke sadržaj korisnih elemenata, dobra učinkovitost, dobra veličina čestica i velika ušteda energije i smanjenje potrošnje.
