Hot Sale High Carbon Ferrochrome for Electric Furnace
ferrochrome Fecr
The smelting methods of high carbon ferrochrome include blast furnace method, electric furnace method, plasma furnace method, etc. Using blast furnace to smelt high carbon ferrochrome can only produce special pig iron with a chromium content of about 30%. As of 2012, high carbon ferrochrome with high chromium content was mostly smelted in a submerged arc furnace using a flux method.
The basic principle of smelting high carbon ferrochrome by electric furnace is to reduce chromium and iron oxides in chromium ore with carbon. The starting temperature of carbon reduction of chromium oxide to generate Cr2C2 is 1373K, the starting temperature of the reaction to generate Cr7C3 is 1403K, and the starting temperature of the reaction to generate chromium is 1523K. Therefore, when carbon reduces chromium ore, chromium carbide is obtained instead of metallic chromium. The carbon content in high-carbon ferrochrome depends on the reaction temperature. It is easier to generate carbides with high carbon content than carbides with low carbon content.
