ABSTRACT:
In charging electrothermic smelting furnaces the charge is fed batchwise to the furnace pot through annular charging units arranged more or less concentrically around each electrode. The charge is supplied to each annular charging unit which surrounds each electrode and consists of a rotatable chamber which comprises at least one bottom member and two substantially vertical side walls. The bottom member and the walls are rotated together for supply of charge to the chamber, then the bottom of the chamber is rotated separately from the walls whereby the charge contained between the walls of the chamber is allowed to fall into the furnace pot through at least one closable opening in said bottom member.
