US 9,557,109 B2 · Apparatus for manufacturing molten metal

Abstract

An apparatus for manufacturing molten metal has a stationary electric furnace, a raw material charging chute, and exhaust duct and a secondary combustion burner in the furnace top, and a shock generator. The raw material charging chute is in one end of the furnace in a width direction and an electric heating region is spaced from the raw material charging chute in the width direction. A raw material layer having a sloping surface extends downward from the one end of the furnace having the raw material charging chute toward the electric heating region, the sloping surface supporting a metal agglomerate raw material layer. The shock generator is provided at least partially within the raw material and extends to the sloping surface, to be in contact with the metal agglomerate raw material layer, and to mechanically overcome hanging of the metal agglomerate raw material layer on the sloping surface.
