摘要
分析了无芯棒拔制小径厚壁无缝钢管时，Ｄ／Ｓ与—ΔＳ之间的关系，同时，采用５７ｍｍ壁厚分别为１３、１４、１４．５ｍｍ的毛管进行了生产试验，根据实验结果总结归纳出了Ｄ／Ｓ与—ΔＳ之间的规律，并根据这一规律指导生产。
Relation of D/S to ( ΔS) was analyzed in sinking small
diameter heavy wall pipe Sinking test by tube blank of 57 minimeter in diameter and 13,14,14 5
minimeter in thickness was done Relation of D/S with( ΔS)was induced Directed production with
this law,satisfactory rusults were gained
