摘要
从薄壁管成型时带钢边缘的纵向拉伸变形及成型过程的稳定性方面推导出确定双层卷焊管成型区长度及成型倾角的解析式,为双层卷焊管成型机组的设计及孔型设计提供了理论依据。
The analytical formula for determining the forming section length and forming inclined angle of the double-layer coil-welded tube is deducted on the ground of the strip edge longitudinal tensile deformation and the forming consistence in the course of thin walled tube formation. The said formula can be used to provide the theoretical basis for the engineering of the double-layer coil-welded pipe forming mill and the pass design therefor.
