摘要
采用经改进的二辊式和六辊式矫直机进行矫直松棒,松棒后管子的内外径尺寸精确,椭圆度小,内外表面螺旋道轻微。介绍了矫直松棒工艺和松棒机的规格、机型选择以及松棒后管子的性能等。
With the straightening-reeling process conducted by means of two-roll and six-roll straighteners, the pipes after reeling are of higher OD & ID dimensional accuracy, less ovality and slighter spiral rolling mark on external/internal surfaces. Also involved are the straightening-reeling process, reeling machine specification, selection of machine type as well as the properties of the pipes after reeling.
