STOKER FEED SYSTEM

摘要

A stoker feed system and method for supplying metal to a melting furnace is disclosed wherein a generally vertically extending feed tube is mounted with its lower end portion submerged below the upper surface of molten metal in the furnace. The feed tube is in communication with at least one feed chute at its upper end portion through which a metal charge is supplied to the feed tube. An additional feed chute is also provided in communication with the upper end portion of the feed tube for supplying carbon to the feed tube. A column of metal chips and carbon is thus formed in the feed tube, and a piston, reciprocally mounted in the feed tube, compresses this column while moving the charge downwardly into the molten metal mass of the furnace.
