ABSTRACT:
A pre-heating assembly to be used for pre-heating ingots being transported to a melting furnace, which includes an inner cylinder constituting a main passage for exhaust gas discharged from a flue of the melting furnace, an outer cylinder which is positioned around the inner cylinder to leave a subsidiary passage for the exhaust gas between the two cylinders, an ingot supplying passage spirally provided along the outermost circumference of the inner cylinder, in which the ingots, each having a spherical configuration like a ball, roll down the passage in succession so that each ingot is pre-heated prior to its introduction into the melting furnace, and a connector support member, on which both cylinders are mounted and the bottom portion of the connector support member is coupled to the outlet of the flue.
