ABSTRACT:
An annealing furnace is disclosed including at least one inner cover for retaining a stack of metal coils to be annealed in an inert atmosphere. A furnace shell is provided for receiving said at least one inner cover and providing an internal furnace environment. A furnace floor is provided for retaining the furnace shell and inner cover. A plurality of burners are received in said furnace floor, and configured around the inner cover so as to fire into the internal furnace environment along side the inner cover without impingement of the flame on the inner cover. A control system sequentially fires each of said plurality of burners in order to establish and maintain a desired thermal distribution among the stacks within the inner cover.
