摘要
针对某冷轧厂光整机生产极限宽度规格的镀锌板产生纵向色差的问题,基于有限元方法,建立了四辊光整机的辊系模型,分析了纵向色差产生的原因,并进一步对支撑辊辊型进行了局部优化。随后的生产实践证明,优化后的辊型解决了纵向色差问题,提高了光整质量和轧辊的使用寿命。
In order to solve the edge defects problem of galvanized strip at temper mill line,based on FE analysis,the causes of longitudinal edge defects were analyzed.In addition,the shape of mill roll was optimized according to the reasons of edge defects.The test results indicate that the new rolls not only improve the distribution of rolling pressure and solve the problems of edge defects but also improve the quality of skin-passed galvanized strip.
