Ferro chrome making process

Jul 10, 2018 Production of Ferro-Chrome. Ferro-chrome (Fe-Cr) is an alloy comprised of iron (Fe) and chromium (Cr) used primarily in the production of stainless steel. The ratio in which the two metals (Fe and Cr) are combined can vary, with the proportion of Cr ranging between 50 % and 70 %. Fe-Cr is frequently classified by the ratio of Cr to carbon (C

    Ferrochrome (FeCr),also known as Ferrochromium, is a ferro alloy with chromium and ferro as its main components. It usually contains 50% to 70% chromium. Mainly used in the steel industry. Low carbon ferro chrome (LC FeCr) is produced by reducing chrome ore with Ferro Silicon Chromium. Usually the chromium content is at least 60%
