摘　　要：从轧制时传动扭矩、辊速差和板形状态分析了宽厚板轧机工作辊辊头断裂的原因,通过优化梯形速度轧制、调整压下规程和建立扭矩联锁保护的措施,降低了轧辊消耗,确保了正常生产和设备安全。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.
