Abstract
An ingot pusher furnace of the vertical air flow type includes adjustable side baffles hingedly connected to lower ends of respective vertical side baffles to prevent the "short circuiting" of heated gases around the ends of an ingot to be heated. The adjustable side baffles are movable from a vertical position to an angled position so that its upper ends are in closely spaced proximity with the outer faces on the end portions of the shorter length ingot so as to produce a more uniform and faster heat transfer along the entire length thereof.
