A rolling - type tribometer has been devised to investigate the boundary lubrication mechanism and clarified the relation between the rolling direction of sheet and friction behavior. Another type of tribometer, U-bending type tribometer has also devised to make dear the relation of frictional condition and thinning mechanism of products. The following results are obtained.1) To diminish the effect of rolling direction on frictional behavior, it is necessary to increase the working velocity and viscosity of lubricants and to decrease of surface roughness of materials.2) To establish the best lubrication conditions and annealing conditions is very important to produce a very thin wall of products. Through this research, these conditions are clarified and possibility of producing 0.1 mm - thickness seamless pipe is shown.

设计了滚动式摩擦磨损仪来研究边界润滑机制，并阐明了板材的滚动方向与摩擦行为之间的关系。另一种类型的摩擦试验机，U型弯曲式摩擦试验机也被设计出来，以明确摩擦条件与产品减薄机理的关系。得到以下结果：1）为了减小轧制方向对摩擦行为的影响，必须提高润滑剂的工作速度和粘度，并降低材料的表面粗糙度。2）建立最佳润滑条件和退火条件对于生产超薄壁产品非常重要。通过这项研究，明确了这些条件，并展示了生产0.1毫米厚无缝管的可能性。
