ANALYSIS OF ROLLING PRESSURE IN WALL-THICKNESS REDUCTION ZONE OF SIZING-ROLL AND OF MANDREL AXIAL FORCE WITH RESPECT TO DOUBLE-COIL-WELDED TUBES(Ⅱ)

  • 摘要: 用解析法求出了锥-柱形芯棒定径辊减壁区轧制压力、总轧制力及芯棒轴向力的计算公式。将计算结果与腰鼓形芯棒相应的结果进行了对比,从而发现了锥-柱形芯棒的优点,提出了提高锥-柱形芯棒使用稳定性的措施。
    Abstract: The calculation formulas are derived with analytical method for rolling pressure, total rolling force and mandrel axial force in wall thinning zone of sizing rolls and a conic-cylindrical mandrel. The calculation result is compared with that relate to the crowned mandrel, which results in the diseovety of the advantages of the conic-cylindrical mandrel and the measures proposed to steadly apply conic-cylindrical mandrel.
