摘　　要：轧机刚度是反映轧机结构性能的重要参数,直接影响着产品的质量和设备的故障率。介绍了轧机刚度的组成及评价指标,分析了某1580热连轧生产线精轧机组轧机刚度的现状,明确了精细化管理对轧机刚度特性保持的重要性。实际生产过程通过加大轧机间隙管理的力度,更换轧机衬板等措施,热连轧精轧机组整体刚度水平明显提高。Rigidity is an important parameter to reflect the construct property of mill, directly affects the quality of products and the failure rate. It is introduced the composition and evaluation indexes for mill rigidity, analyzed the present status of rigidity of finishing rolling set of some 1580 hot continuous rolling production line, stated the importance of the fine management to keep the mill rigidity. In actual production, with measures ： strengthening mill gap management and exchanging mill liner, the overall rigidity level of the set is obviously improved.
