本文研究横向冷轧钢管时分析确定单位压力的方法。为了推导公式,我们应用变形的总能量最小原理。横轧时的变形区示于图1a。其过程可视为轧辊旋转不断送进金属进行轧制和管子在
This paper studies the method of determining the unit pressure when analyzing cold-rolled horizontal steel tubes. In order to derive the formula, we apply the principle of minimizing the total energy of deformation. The deformation zone at the time of cross rolling is shown in Fig. 1a. The process can be seen as a continuous rotation of the rollers to feed the metal into the tube and roll it over
