High-carbon ferrochrome smelting blast furnace method, electric furnace, plasma furnace method. Blast obtained using only about 30% chromium cast iron was special. Currently, high-carbon ferrochrome chromium high flux method most used in the submerged arc furnace smelting.
The basic principle of high carbon ferrochrome smelting furnace method is to use a carbon reduction of chromium ore of chromium and iron oxides Stainless steel springs. Carbon reduction of chromium oxide generated Cr2C2 start temperature of 1373K, the reaction initiation temperature generated Cr7C3 1403K, and the reducing reaction generating chromium start temperature of 1523K, and thus when the carbon reduction of chromium ore is obtained chromium carbide,stainless steel wire rod chromium metal instead of . Ferrochrome carbon content level depends on the reaction temperature. Generate high carbon content of carbide is easier than generating low carbon content of carbide.
