ABSTRACT:
An ingot pusher furnace of the vertical air flow type includes distributing means for preventing short circuiting of a gaseous medium around the ends of ingots to be heated so as to produce a more uniform heat transfer along the entire length of the ingots. The distributing means comprises a pair of air distribution baffles which force the gaseous medium contained in an enclosure to flow towards the center portions of the ingots so as to facilitate uniform heating throughout the ingots. In an alternate embodiment, the distributing means comprises a pair of movable side baffles which is movable to an angled position so that its lower ends are adjacent the ends of the ingots.
