Abstract
Disclosed is a method and apparatus for controlling lateral unstable movement and camber of a strip being rolled in which the lateral displacement and the camber magnitude of the strip being rolled are directly detected. The lateral unstable movement is controlled by changing the right and left roll gaps of the horizontal rolling mill while the camber of the strip is corrected by changing the path line through the vertical rolling mill. As a result, the lateral unstable movement of the strip can be prevented so that the rolling operation can be carried out in a stable manner. In addition, the quality of the rolled strip can be improved and the yield can be increased.
