摘　　要：介绍了唐钢一冷轧重卷机组的生产流程和拉矫机状态。通过对拉矫机使用中拉矫辊消耗量大,经常出现断辊、掉辊造成带钢表面划伤缺陷等现象的研究,找出多项影响拉矫辊使用寿命的原因。经过辊端轴承结构的优化、装配质量的优化、生产工艺参数的优化、检修制度的完善,提高了拉矫辊的寿命,降低了备件和检修成本,确保了产品质量的稳定性。This paper introduced the production process and the condition of tension leveler in the recoiling line of Tang steel 1# cold rolling plant. Through the research of the pulling-straightening roller＇s high consumption and strip surface scratched by roller breakage or falling, it is found the reasons that influenced the life of the pulling-straightening roller. By optimizing some equipment and parameters, such as the bearing structure in the roller end, assembly quality, the production process parameters and the repair system, the service life of the pulling-straightening roller was improved, the cost of the spare parts and maintenance were reduced, and the stability of product quality was ensured.
