Summary:A method and an apparatus for stopping the flow of metal from the taphole of a furnace. The method comprises the step of blowing air into the taphole with sufficient pressure to reverse the flow of the molten metal, and then reducing the pressure to a value sufficient to hold the metal in the furnace. The apparatus comprises a pipe adapted to be inserted into the taphole and of sufficient dimension to seal the taphole, and means for blowing air into the pipe initially at a predetermined pressure so as to reverse the flow of the molten metal in the taphole and then at a reduced pressure sufficient to hold the metal in the furnace.
