摘　　要：用自行设计的实验装置真实描述出无缝管轧制变形区内单位轧制力，纵、横向摩擦力的分布规律，绘制出变形区各点的摩擦力分布和金属流动轨迹图。With self-designed testing system,the distribution laws of unit pressure,longitudinal and lateral friction stresses in the rolling deformation zone of seamless steel tube are actually demonstrated,and the locus of metal flow and the point-to-point friction stress distribution in the same deformation zone are also drawn out.

关 键 词：摩擦力 金属流动 无缝钢管 钢管 轧制
