摘要
简要介绍了螺旋焊管成型原理和成型角概念.用包钢CSP线生产的L245钢连铸坯作原料,对不同直径焊管的成型角进行了分析,结合现场情况得出了成型角、成型内角和成型外角的优化公式.现场生产表明,优化值和生产实测值吻合较好,焊接后焊缝质量良好.
The forming principle and forming angle of spirally-welded tube processing were introduced. The forming angle, interior angle and the exterior angle of L245 steel slab were analyzed according to the different tube diameters, while the raw material was produced by CSP technology in Baotou Iron and Steel （Group） Co. The results show that the optimization formula can fit well with the measured value in the factory, and the quality of spiral welding zone is good.
