Bulk Ferrochrome The carbon content in ferrochrome depends on the reaction temperature. It is easier to produce carbides with high carbon content than those with low carbon content. 3, smelting high carbon ferrochrome raw materials smelting high carbon ferrochrome raw materials are chromium ore, coke and silica. Chromium ore Cr2o3鈮?40%, Cr2o3/Feo鈮?.5, S< 0.05%, P< 0.07%, Mgo and Al2o3...
