Features of Smelting Carbon Ferrochrome in AC and DC Electric Arc Furnace
The technology of ferrochrome smelting in DC furnaces is described. A comparison is made with the technology of smelting ferrochrome in AC furnaces, the advantages and disadvantages of both technologies are noted. The ways of increasing the production efficiency of ferroalloys in direct current furnaces have been outlined. A promising method of intensification is the use of ore-coal briquettes.
