从宏观塑性变形的角度,通过对轧制过程中动量变化的分析,提出了板带轧制的力能分析的微分形式和积分形式,建立了轧制力和轧制力矩的理论公式.该公式摒弃了传统公式中采用过多的经验系数,清晰地揭示了轧制力、轧制力矩、金属屈服强度、摩擦因数等各变量之间的相互关系,使得咬入角、中性角等有关变量的物理意义进一步明确.最后通过对一次实际轧制过程的仿真计算初步验证了本文公式的正确性. From the perspective of macroscopic plastic deformation, through the analysis of the change of momentum in the rolling process, the differential form and integral form of force analysis of strip rolling are proposed, and the theoretical formula of rolling force and rolling torque is established. Abandon the traditional formula using too much empirical coefficient, clearly reveals the rolling force, rolling torque, metal yield strength, the friction coefficient between the various variables such that the bite angle, neutral angle and other related variables The physical meaning is further clarified.Finally, the correctness of the formula in this article is verified through the simulation of an actual rolling process.
