摘要
针对48英寸大口径厚壁直缝焊接钢管的生产要求,通过对卷曲式JCOE制管过程芯轴卷曲成形时钢板回弹量的理论分析计算,提出了根据回弹量确定成形芯轴直径的方法,并利用所得方法确定了48英寸大口径直缝焊接钢管的成型心轴直径。
By theoretically analyzing and calculating spring back during pipe forming with the coiled-type JCOE process ,a method based on spring back is submitted to decide the diameter of mandril. The acquired method has been used to determine mandril diameter for forming 48＂ heavy wall LSAW pipe.
