在铝带快速铸轧新技术与设备的研制开发中 ,由于铸轧辊工作在高温、高压力、高轧制速度的条件下 ,而且铸轧辊与铸轧产品质量的各种指标有着直接的关系 ,因此 ,其强度设计是关键技术之一 .作者运用有限元软件Al gor和工程技术语言Matlab编程对 2套某厂正常使用的铸轧辊以及针对快速铸轧而设计的铸轧辊进行了强度仿真计算和分析 ,采用将辊套和辊芯之间的热装配应力、扭矩产生的剪应力和轧制力产生的轧制应力三者分别进行预处理后再叠加 ,然后进行应力场综合分析计算的方法 ,获得了快速铸轧状态下铸轧辊在热装配预应力、轧制扭矩以及轧制力等多应力场条件下更符合工况的综合应力状态 .此外 ,探讨了改善铸轧辊应力状态的策略及方法 ,为实现铸轧辊适应铝材快速铸轧工艺提供了一种新的分析及设计方法 ,这对改善铸轧辊的强度设计具有指导意义 .
In the rapid development of aluminum strip casting technology and equipment research and development, as the casting roll work in the conditions of high temperature, high pressure, high rolling speed, and the casting roll and casting quality of the various indicators have a direct relationship, Therefore, the strength of the design is one of the key technologies.The author uses the finite element software Al gor and engineering language Matlab programming on two sets of factory normal use of casting roll and casting roll for rapid casting designed intensity simulation calculation and Analysis, using the heat between the roll sleeve and roll core assembly stress, the shear stress generated by the torque and the rolling force generated by the rolling stress pretreatment after pre-treatment and then superimposed, and then conduct a comprehensive analysis of the stress field calculation method, The comprehensive stress state of the casting roll under rapid casting condition is obtained under multi-stress conditions such as pre-stressing, rolling torque and rolling force etc. In addition, the strategies and methods to improve the stress state of casting roll , To provide a new analysis and design method for the casting roll to adapt to the rapid casting process of aluminum, which is instructive for improving the strength design of the casting roll .
