Abstract

The manufacture of thin-walled narrow pipe from 32NKD Super Invar alloy by drawing is studied. The drawing forces on the mandrel and the pipe blank are determined. The influence of the lubricant on the frictional forces is analyzed. The linear-expansion coefficient of the thin-walled pipe produced by drawing is compared with that of an undeformed sample of 32NKD alloy, as a function of the temperature.

窄壁超高殷钢管的制造

摘要

研究了由32NKD Super Invar合金通过拉伸制造薄壁窄管的方法。确定在心轴和管坯上的拉拔力。分析了润滑剂对摩擦力的影响。将通过拉伸生产的薄壁管的线性膨胀系数与未变形的32NKD合金样品的线性膨胀系数进行比较，以作为温度的函数。
