摘　　要：针对以往机架设计中窗口尺寸与轴承座的配合间隙缺乏理论依据,且未考虑轧机辊系侧向力对机架窗口变形的影响,通过对某厂六辊轧机辊系的稳定性计算,求得轧辊辊系的水平力;采用有限元方法对轧机机架在轧制力和辊系水平力共同作用下的变形进行分析。结果表明,辊系轴承座侧向力对机架窗口水平方向的变形有很大影响,只有考虑了侧向力的作用,才能精确计算出机架窗口的变形。There are few theory evidence for the corporate gap of stand design between windows and bearing chock,and the effect of roll system lateral force on the stand windows was ignored.Based on a 6-h mill,the horizontal force was obtained by roller system stability calculation.The stand deformation worked by rolling force and roll system horizontal force was analyzed by finite element method.The results show that the lateral force of roll system bearing chock have great impact on stand windows deformation.The deformation of stand widows could be calculated exactly by lateral force considered.
