工艺因素对钢管外径精度的影响

The Influence of Process Factor on Exterior Diameter Precision

研究了空拔减径量、模角、钢管材质和加工硬化对冷拔钢管外径精度的影响，为合理拟订冷拔工艺、高精度地生产冷拔钢管奠定了基础。

The articale studies the influence of the O.D reduction of sink drawing, mold angle, steel tube material and work hardening on cold drawing steel tubes exterior diameter accuracy. Its the basis of drawing up the cold drawing process reasonably and producting high precision cold drawing steel tube.
