ABSTRACT:
A continuous heat treating furnace in which independent sectioned chambers are provided at least in part of a pre-heating/pre-cooling zone in the furnace body, with a cooler or heater being provided in suction ducts of the sectioned chambers so as to rapidly heat or cool the metallic strip through operation of dampers disposed in the suction ducts, thus making it possible to alter heat curves as required for heat treatment of various metallic strips.
