Production of high Carbon Ferro-chrome using Talcher low temperature carbonization coke as the reductant in the Pilot submerged arc smelting furnace

The feasibility of using Talcher low temperature carbonized coke for the production of high carbon ferro-chrome was investigated in the pilot submerged are a furnace of the National Metallurgical Laboratory. Operational conditions were standardized after comprehensive pilot plant trials for the production of high carbon ferro-chrome containing 64.4% Cr, 5.8% Si and 6.2% C. The power consumption averaged 454 KWH per tonne of high carbon ferro-chrome produced. It was observed that Talcher L.T.C. coke could be most successfully employed for the production of high carbon ferro-chrome.
