ABSTRACT:
A convection muffle furnace for brazing and/or annealing a workpiece includes a muffle having towers formed integrally therewith and being mounted movable relative to a top wall of a furnace. Circulation fans are mounted in the towers so as to move along with the muffle during its expansion and contraction for producing forced convection heat transfer.
