Abstract

The present invention relates generally to a smelting operation or the like, by which molten metal is produced from a metal oxide after metal oxide agglomerates are directly reduced and melted with a carbonaceous material in an electric heating and melting furnace. More specifically, the present invention relates to an electric furnace for producing molten metal that has material recycling capability, especially in-process material recycling capability.
