作为对切分轧制时轧制力计算方法的探讨 ,文中以武钢 1 1 5 0初轧机切轧钢坯工艺的轧制力计算为例 ,根据力学和运动学知识 ,在对轧件的受力及运动情况具体分析的基础上 ,用近似法确定出轧件与轧辊高向上的相对位置及一系列与轧制力计算有关的参数 ,并采用分区计算的思想 ,计算出各区的平均单位压力及接触面积 ,从而计算出总轧制力。 As a discussion of the calculation method of the rolling force during the split rolling, taking the calculation of the rolling force of the cutting and rolling billet at the initial rolling mill of WISCO 1 150 as an example, according to the mechanics and kinematics, And the specific analysis of the movement, based on the approximation method to determine the relative position of the workpiece and the roll up and a series of parameters related to the calculation of the rolling force, and the idea of ​​partition calculation to calculate the average unit pressure in each area and Contact area, to calculate the total rolling force.
