Abstract
An ingot pusher furnace includes means for reducing heat loss from the charging and discharging ends of the furnace so as to produce a more efficient and uniform heating of the ingots. The pusher furnace includes support rails which extend between a first opening in the front wall and a second opening in the rear wall and terminates inside of the charging and discharging doors. The charging and discharging doors extend below the support rails in their closed position so as to provide a positive seal.
