In the bright solution treatment of some copper alloys and the bright annealing of high nickel materials for electronic materials, it is necessary to heat the material temperature to 900 to 1100 ° C. On the other hand, as a heating method of the metal strip, there are a convection heating method and a radiant heating method. From the viewpoint of the heat resistance of the circulation fan, a convection heating method using a circulation fan is employed up to a heating temperature of 850 ° C. As for the temperature, a radiant heating method using a muffle or an electric heater is employed. Therefore, the radiant heating method is used to heat the above-mentioned copper alloy or high nickel alloy. However, the radiant heating method largely depends on the emissivity of the material surface, and the heat transfer coefficient of a material requiring bright annealing is only about 60% at 100 ° C. as compared with the convection heating method. The annealing furnace becomes longer, and the installation space becomes larger. Further, since the annealing furnace becomes longer, the furnace wall loss is large, the thermal efficiency is poor, and the consumption of a protective atmosphere such as a reducing atmosphere gas is increased. SUMMARY OF THE INVENTION It is an object of the present invention to provide a vertical continuous annealing furnace for a metal strip that can solve the above-mentioned problem by performing the same function as a conventional annealing furnace by using the reversing roll as a heating roll.
