摘　　要：以带钢不产生塑性变形、空转辊不打滑为原则,研究稳定夹送辊理论设计方法。建立了夹送力计算模型、带钢临界塑性变形模型、空转辊打滑模型,将三个模型耦合迭代,理论计算了稳定夹送辊传动电机功率、辊径及空转辊空间布置尺寸,确保带材不会产生塑性变形和擦划伤。比较原有的经验设计方法,更加准确、可靠。The theoretic design method of the stabilizing pinch roll is studied to ensure no strip plastic deforma-tion and no slipping of the idle roll. The pinching force calculation model, the strip critical plastic deformation model and the slipping model of idle roll are established. These three models are coupled and iterated. The drive motor power, the diameter of the stabilizing pinch roll and the space layout dimensions of idle roll are the-oretically calculated to guarantee no strip plastic deformation and no scrape, the theoretic design results are more accurate and reliable in comparison with the available experience design method.
