摘　　要：针对某公司引进的德国安德里茨S6十八辊轧机的下侧支撑定位键自投产以来因定位不准、牌坊键槽受力面损坏造成轧机不能稳定运行而严重影响轧机正常生产的问题,根据实际情况对定位键进行受力分析,并结合生产运行情况,重点对特殊异常状态下的定位键失效问题进行分析,提出了将2个定位键结构改进为键与键套相配合的结构形式。经实践表明,改进定位键结构后,大大提高了定位键的安全系数,彻底解决了定位键失效问题。The underside support positioning key of Andritz S618-high mill imported by a certain company from Germany has been put into production,and the mill can not run stably because of the damage of the stress surface of the key slot of the archway,which seriously affects the normal production of the mill.This paper analyzes the force of the positioning keys according to the actual data,and combines the analysis of the production operation,especially in some special abnormal cases,proposes that the structure of the two positioning keys is improved into the structure of the key and the key sleeve,which greatly improves the safety factor and solves the problem thoroughly.
