Production of low carbon ferro-chrome from high carbon ferro-chrome

The paper records the result of the process developed for producing low carbon ferro-chrome from high carbon ferro-chrome. The process consists in mixing together molten ferro-chrome and ferro-silicon whereby carbon is eliminated and burns to carbon monoxide. The chrome-silicide so formed is treated in an electric furnace for silicon removal with a chromium rich slag made separately. The power requirements of the silicide formation has also been worked out. (V.S. Sampath, Junior Scientific Officer and P.P. Bhatnagar, Assistant Director, National Metallurgical Laboratory)
