Technological Causes of Vertical Workpiece Asymmetry in Plate Rolling Mills
2022年8月16日 Abstract. The SKI effect is a serious problem occurring during the rolling of metal sheets in plate mills. This term stands for the vertical bending of the workpiece front edge at the stand output. The downward bending results in strikes as the workpiece is moving along the table rollers, leading to its jamming and emergency stops of the mill.
