| Abstract: | The reason for failure of roll head of working roll of wide-thick plate mill is analyzed from the fields of driving torque,difference of roll rotational speed and profile shape status in rolling.With measures adopted: optimizing trapezoid speed rolling,adjusting draft schedule and setting up torque interlocking protection,the roll consumption is reduced. |
