Title:
ELECTRIC FURNACE FOR PRODUCING MOLTEN METAL HAVING MATERIAL RECYCLING CAPABILITY
Document Type and Number:
WIPO Patent Application WO/2012/074962
Kind Code:
A3
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.
