ABSTRACT:
A heat treating furnace for a metallic strip, which includes a heat exchanging zone and a heating/soaking zone provided within a furnace body by dividing the furnace body with a partition wall disposed in a widthwise direction so as to transport the metallic strip in a confronting state through the heat exchanging zone. The heat exchanging zone is further provided with nozzles for jetting atmospheric gas of the heat exchanging zone onto opposite surfaces of the metallic strip being transported, an atmosphere supply duct for the nozzles, and a circulation fan so as to utilize sensible heat discharged or dissipated from the metallic strip during pre-cooling for pre-heating the metallic strip.
