Abstract
A scrap charging apparatus for an electric arc furnace uses a skip hoist to supply scrap to a holding bunker having diverging end walls extending between converging side walls. The containment space for the scrap is increased by this wall arrangement and provides an impetus in the bunker for scrap flow to an underlying scrap delivery chute. The scrap delivery chute is formed by an elongated scrap carrying trough having a greater width than the exit width of the scrap holding bunker for delivering scrap to a charging opining for an electric arc furnace A superstructure supporting the scrap holding bunker at an elevated and lateral spaced location from the electric arc furnace. A ram controlled by a drive incrementally advances scrap along the scrap delivery chute for introducing successive preselected volumes of scrap to a charging opining for an electric arc furnace.
