通过实验验证了三辊楔横轧中轧件轴平行部对轧辊变形楔平直部分碾压力的存在,它是楔横轧时轧制力的重要组成部分。给出了辗压力作用面积公式和多元回归得到的辗压变形影响系数的经验公式。
The existence of rolling force in the straight part of the deformed wedge of three-roll cross wedge rolling is verified by experiments, which is an important part of the rolling force during cross wedge rolling. The formula of influence area of rolling force and the influence coefficient of rolling deformation obtained by multiple regression are given.
