试验对轧制力矩特性进行了探讨。通过分析力矩计算模型,优化力臂系数及自适应算法,提高了力矩计算精度。通过采用应变测试的方法对实际力矩进行测量,进一步验证了力矩计算的准确性,95%以上道次的力矩计算偏差可以控制在10%以内。同时,还进一步得出了绝大部分道次的力矩放大倍数为1.2~1.45,个别道次力矩放大倍数为1.75~1.9。试验结果为现场实际力矩的使用提供了重要依据。在设备正常运转的情况下,最大使用力矩在原有基础上提高了15%,轧机能力得到进一步发挥,为品种开发提供了更好的条件。
The characteristics of rolling torque were discussed. By analyzing the moment calculation model, optimizing the arm coefficient and adaptive algorithm, the torque calculation accuracy is improved. By using the method of strain measurement to measure the actual torque, the accuracy of torque calculation is further verified, and the calculation error of torque of more than 95% of the passes can be controlled within 10%. At the same time, it is further concluded that most of the times the moment magnification is 1.2 ~ 1.45, the individual times moment magnification is 1.75 ~ 1.9. The test results provide an important basis for the actual use of the on-site torque. In the case of normal operation of the equipment, the maximum moment of use has been increased by 15% on the original basis, and the mill capacity has been further developed, providing better conditions for variety development.
