【摘要】 本文在分析四辊轧机轧制板带时板带宽度对板凸度影响的基础上，采用轧辊弹性变形影响函数法，计算了四辊轧机板带宽度与板凸度的相互关系，同时确定出产生最大板凸度的板带宽度。理论计算值与文献［１］的实测值基本吻合，从而为确定合理的板带宽度提供必要的理论依据。更多还原

【Abstract】 Based on the influence of plate width on its crown,as being rolled in a 4-high mill,the influence function for rolls elastic deformation is used to calculate width-crown relation and determine the plate width causing maximum crown as well.The final results of the theoretical calculation are basically close to the measured da-ta. Therefore it provides a necessary theoretical basis for determining a reasonable plate width.更多还原
