Abstract

PURPOSE:The annealing furnace of box type at which the one-sided heating of the inner cover at the direct firing part of the burner has been made to be avoided and the uniform annealing for the coil has been enabled to be performed, by equipping the rotatable outer cover at the outside of the inner cover.
