Abstract

A method and a device for directly feeding liquid metal into an electric furnace. A carriage carrying a ladle filled with molten metal is moved forward into a starting position adjacent the electric furnace then lowered and horizontally translated until the upper rim of the ladle is located over the electric furnace. The ladle is then tipped and gradually raised and translated to keep the upper ladle rim in a position in which the liquid metal can be poured into the furnace. The ladle is tilted back, lowered and horizontally translated to return it to the starting position.
