ABSTRACT:
During the process in which a metal strip is moved in a floating condition, the metal strip is first heated, and thereafter cooled and annealed. In cooling the metal strip, the metal strip is cooled so that both edges widthwise thereof are lowered in temperature more quickly than the temperature of a central portion widthwise thereof. The metal strip is cooled in a manner as described whereby a great thermal stress is not introduced in the metal strip and consequently, the metal strip is cooled without being wrinkled.
