摘　　要：针对六辊轧机在金属轧制过程中的性能问题,采用有限元分析法对其进行优化研究。首先,建立了六辊轧机的有限元模型,分析六辊轧机性能不足之处。在此基础上,提出了针对六辊轧机的优化方案,主要包括增设稳定辊、更换工作辊传动轴、增加工作辊窜辊机构以及改造仪表电气系统等。经过优化后,试验合格率达到92%,试验品整板同板差平均值约为5.8μm,相比于六辊轧机优化前,六辊轧机优化后的整板同板差减少了9.5μm。数据表明,六辊轧机在实际生产中的应用效果显著提升,整板和边部的同板差均明显降低,钢板平整度得到明显提高,有效提升了轧制过程的稳定性以及产品质量。Finite element analysis method is used to optimize the performance of six high rolling mill in metal rolling process.Firstly,a finite element model of the six high rolling mill was established to analyze its performance shortcomings.On this basis,an optimization plan for the six high rolling mill was proposed,mainly including the addition of stabilizing rollers,replacement of the working roller drive shaft,addition of the working roller running mechanism,and modification of the instrument and electrical system.After optimization,the pass rate of the test reached 92%,and the average difference between the whole plate and the plate of the test sample was about 5.8μm.Compared with before the optimization of the six roll rolling mill,the difference between the whole plate and the plate of the six roll rolling mill after optimization was reduced by 9.5μm.The data shows that the application effect of the six high rolling mill in actual production has been significantly improved,with a significant reduction in the same plate difference between the whole plate and the edge,a significant improvement in the flatness of the steel plate,and an effective improvement in the stability of the rolling process and product quality.
