Ferrochrome Production Process

  • Balasore Alloys : Production Process

    Production Process Ferrochrome (FeCr) is a corrosionresistant alloy of chrome and iron containing between 50% and 70% chrome Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures Cr Ore, an oxide of chromium and iron, is reduced by coal and coke to form the ironchromium alloyProduction process for the FeCr is highly electric energy intensive since all the heat needed for the endothermic reduction reactions and to achieve thermodynamic equilibrium in the furnace is supplied through electrical energy only Thus electrical energy is the most vital input in the processProduction of FerroChrome – IspatGuruMedium, low and microcarbon ferrochrome alloy are generally made of siliconchromium alloy, chromite and lime Desiliconization is refined with a 15006000 kV electric furnace It is operated with a high alkalinity slag (CaO/SiO2 is 16 to 18) Lowcarbon, microcarbon ferro chrominum is also produced on a large scale by the heat exchange methodUnderstanding The Manufacturing Process Of
