采用四种辊径比,两种带钢原料,三种张力制度,两种润滑条件和各种压下率对异径单辊传动轧制的力能参数进行了实验研究,在实验中采用了一种新的张力传感器的标定方法,文中用上界法推导了一个求纯轧制力矩的理论公式,给出了一个用计算机求解的,考虑了从动工作辊和其支持辊的所有附加力矩的轧制压力计算方法,这些理论计算结果和作者的实验结果符合较好,针对冷轧带钢的常见范围,还推导了一个精度和计算机解十分接近的轧制压力简化公式。因此,可在不用计算机的条件下,不需迭代,便可完成轧制压力,轧制力矩的计算。
In this experiment, four kinds of roll diameter ratio, two kinds of strip raw materials, three kinds of tension system, two kinds of lubrication conditions and various reduction rates were used to experimentally study the force and energy parameters of the reducer single- A new calibration method of tension sensor is proposed in this paper. The upper bound method is used to derive a theoretical formula for calculating the pure rolling torque. A computerized solution is given to consider all the additional moments of the driven work roll and its backup roll The calculated results are in good agreement with the experimental results of the author. According to the common range of cold-rolled strip, a simplified formula for the rolling pressure whose accuracy and computer solution are very close is also deduced. Therefore, the calculation of the rolling pressure and the rolling torque can be done without iteration without a computer.
