Abstract Concave work rolls with negative crown are commonly used in a large number of 1 250 mm hot continuous rolling production lines in China. Due to the configuration of the roll and the characteristics of the rolling process,the work rolls will suffer serious "cat ear" wear,resulting in local high points in the section of the hot-rolled strip. In order to improve the wear of 1 250 mm hot rolling work roll and improve the strip profile quality,a control strategy for 1 250 mm hot rolling work roll wear was proposed. While ensuring the plate and strip rolling stably,the wear of the work roll was controlled by optimizing the roll shape curve and the work roll shifting strategy. This strategy has been applied to Delong iron and steel company,the industrial test showed that this strategy can reduce the amount of work roll wear,make the roll wear more even and increase the control ability of roll bending. The work roll rolling mileage per unit cycle is extended by 40%,which has research value and promotion prospect for 1 250 mm hot continuous rolling production line work roll wear control.

Key words： wear of work roll roll shape curve roll shift strategy bending force strip profile quality
