| Abstract: | According to appearance features and distribution rules of scars in a hot strip mill,the reasons to form the scar defect were analyzed.Thread rolling and jump rolling data were reset for side-guide of finishing rolling,electrical program was optimized to ensure the linearization of side-guide of crop shear,and pressure transducers were also installed.As a result,the ratio of scars in hot strip was reduced effectively. |

| Keywords: | scar thread-rolling side-guide of crop shear linearization |
