Abstract
A method is provided for continuous smelting of ferrochrome with less than 6.5% by weight carbon content in an electric reduction furnace. In the described method, separately from the normal mixture of ores continuously fed into the melt, and consisting of lumpy ore agglomerated fine ore, part of the mixture of ores is introduced as wholly or partially unreduced oxide-rich chrome ore directly into the bath of slag. The introduction of the oxide-rich chrome ore, which is fed separately from the normal mixture of ores, may be made through a hollow electrode into the bath of slag.
