ABSTRACT:
During the process in which an aluminum strip is moved in a floating mode, the strip is first heated, then cooled and annealed. When the aluminum strip is cooled, the strip is moved while being curved into a wave-like form toward the moving direction thereof. The aluminum strip is curved in a manner as described, and as a result, the aluminum strip increases in antibuckling stress. The increased antibuckling stress overcomes a thermal stress produced in the direction of the width of the aluminum strip during the process of cooling. Accordingly, the aluminum strip is cooled without formation of wrinkle parallel to the longitudinal direction of the strip.
