ABSTRACT:
A method and apparatus for feeding pulverant raw material to an arc furnace having a plurality of arcing locations defined by vertical electrodes. A vertical feed tube gravitationally conveys the raw material to a central location inside the furnace which is above the arcing locations. A rotatable deflector is located at the bottom of the feed tube and is rotated in step-wise fashion to direct raw material from the feed tube to each of the arcing locations. A fixed deflector is located at each arcing location to confine the raw material fed into the furnace predominantly to the arcing locations. By locating most of the raw material at the arcing locations, the feeding mechanism of the present invention improves the stability of the arc and the melting efficiency of the furnace.
