Ferrochrome - an overview ScienceDirect Topics

Isobel Mc Dougall, in Handbook of Ferroalloys, 2013. 4.2.3 Preheating. In ferrochrome smelting in closed furnaces, the feed material may be preheated before it enters the furnace. Lumpy ore, briquettes, sintered pellets, and prereduced pellets may all be preheated successfully. The energy used to preheat the feed material comes from the combustible CO contained in the furnace exhaust gas.
