    帶芯棒拔制鋼管直徑變化的研究

    STUDIES OF DIAMETER VARIATION OF STEEL TUBE BEING DRAWN WITH MANDREL

    • 摘要: 通過(guò)芯棒位置、拔制變形量等試驗(yàn),研究了冷拔管外徑擴(kuò)大量和內(nèi)徑縮小量的變化規(guī)律,為準(zhǔn)確控制冷拔管直徑偏差奠定了基礎(chǔ)。

       

      Abstract: By carrying out a series of tests regarding mandrel position, deformation amount under drawing and so on, an investigation on the law governing the variation of O. D. increase and I. D. decrease of the tube being cold-drawn has been made. The result will provide the basis for properly controlling diameter deviation of the cold-drawn tube.
