Abstract
A method for feeding fines or granules into a light-arc furnace. A hollow electrode provided with a feeding channel is utilized, and is preferably a hollow Söderberg electrode. A conveyor introduces the fines or granules into the feeding channel so as to maintain in the feeding channel a hollow material in which a lower end is smelted in a molten metal bath.
