Abstract
A metallic charge is introduced into an electric furnace in a continuous fashion using as a feeding device an unobstructed tubular container of undulant or zig-zag shape. The feeding device is oriented horizontally and is rotated about its longitudinal axis causing the charge to advance through the container and discharge into the furnace through a roof port. The feeding device can handle a variety of material sizes and shapes, ranging from powder to shredded scrap, singly or in admixture, without modification. Hot furnace gases are vented through the feeding device, thus cooling the gases and preheating the furnace charge. See also U.S. Pat. 3,900,696.
