METHOD FOR THE PRODUCTION OF FERROCHROMIUM

摘要

Described is a method for the production of ferrochromium and a rotary furnace employed in such method. Raw chromium ores, fluxes and carbonaceous reducing agent(s) are charged into a rotary furnace into which oxygen or oxygen-enriched air is blown to effect smelting reduction. Hot exhaust gases from the rotary reducing furnace are used for pre-heating and pre-reducing of the materials for saving the energy considerably as contrasted to conventional methods.
