Abstract
A scrap charging apparatus for an electric arc furnace includes a scrap holding bunker having diverging side walls extending between end walls separated by a scrap discharge opening supplying scrap from a fall space in the bunker to a scrap discharge chute. The end wall remote to the scrap discharged opening of the chute slopes at an acute angle to organized scrap entering the discharged opening. A throat opening for scrap passing into the scrap discharge chute is controlled by a pivotal scrap jam relief gate moveable between a scrap metering position, a relief position and a scrap compacting position.
