摘要： 在采用影响函数法分析轧辊弹性变形的基础上,提出一种热带轧机工作辊初始辊型曲线的设计算法.指出合理分配精轧机组各机架带钢入、出口凸度范围对工作辊初始辊型曲线设计具有重要的作用,并提出一种各机架带钢入、出口凸度范围的确定策略.采用提出的算法对某厂1 250 mm热带轧机精轧机组优化了其工作辊初始辊型曲线,并进行了现场实际生产实验.实验结果表明:带钢的实测凸度满足该厂目标凸度的要求,证明了该算法的合理性.

Abstract: Introducing the influence function into the analysis of roll's elastic deformation, a design algorithm was proposed for the initial profile of work roll on hot strip mill. It was found that the reasonable strip crown distribution at entry and exit of each and every finishing stand plays an important role in the initial profile design of work roll. And a strategy was proposed to determine such a distribution. The work roll's initial profiles of 1250 mm HSMs in tandem were designed and optimized by the proposed algorithm. The results of in-situ tests showed that the measured strip crowns meet the requirements of target crown, thus verifying the reasonability of the algorithm.
