Abstract:
    The present invention relates to method of controlling convexity degree of strip steel, and is especially method of controlling convexity degree of hot rolled strip steel based on smoothly changed rolling rule. The method of controlling convexity degree of hot rolled strip steel includes dividing the successively connected hot rolling frames into upstream rolling frames, middle rolling frames and downstream rolling frames; regulating the reduction degrees of the rolling frames during rolling the first 80-120 strip coils one coil by one coil; and maintaining the reduction degrees of the rolling frames unchanged in the subsequent rolling. The method of the present invention has smooth change in the load distribution in the rollers, simple function structure, easy regulation and precisely controlled convexity degree and straightness of the hot rolled strip steel.
