| 摘 要： | 冷轧钢卷卷取过程中，带材的板形与板凸度以及卷取张力的横向分布决定钢卷内部的应力分布。同时，带材与卷筒之间、带材与带材之间的摩 擦力对应力分布的影响不可忽略。此外，由于层间接触表面缝隙的存在，钢卷必须按各向性体处理。基于上述因素，提出了一套新的三维数学模型，以计算钢卷内部应力分布，并根据降低钢卷在罩式退火粘经率的要求，研究了钢卷的卷取张力制度。

| Abstract: | In cold strip coiling process, the stress distribution in coil is determined by shape, crown and the transverse distribution of coiling tension At the same time, the influence on stress distribution of friction between strip and drum, between strip and strip can't be ignored In addition, due to the gap between layers, the coil must be treated as anisotropic body Based on above factors, a new three dimensional mathematic model has been developed to calculate the internal stress distribution in coil, and study the coiling tension control to reduce coil sticking rate in the bell type annealing furnace |

| Keywords: | crown coiling tension friction three dimensional distribution coil stick ing rate |
