针对轧辊失效问题,基于数值模拟分析了带钢轧制过程轧制区轧制压力、摩擦力及轧辊内应力的三维分布情况。确定了不同因素对轧制区接触状态影响的对比方法,对接触区工作辊的三维应力分布进行了详细地研究。这对探索轧辊的失效机理是非常重要的。 Aiming at the problem of roll failure, the three-dimensional distribution of rolling pressure, friction force and internal stress in the rolling zone of strip rolling process was analyzed based on numerical simulation. The contrast method of different factors affecting the contact state in the rolling zone was determined and the three-dimensional stress distribution of the work roll in the contact zone was studied in detail. This is very important to explore the failure mechanism of the roll.
