摘要:
为研究热轧卷板质量对HFW焊管成型及焊接的影响，从热轧卷板成分、组织、几何尺寸、外观及纵剪质量等方面进行了分析。结果表明，卷板的成分、带状组织及夹杂物直接影响HFW焊管的可焊性及性能；卷板的宽度、厚度等几何尺寸不但影响成型焊接质量，而且影响焊道毛刺的清除质量；卷板的镰刀弯、波浪弯等外观缺欠影响焊管成型和焊接稳定性，容易导致焊接缺陷的发生；卷板纵剪断面质量也直接影响焊接的质量。针对以上影响因素，从卷板冶炼、轧制及纵剪工艺等方面制定改进措施，从而为高频焊管焊接提供焊接性、纯净度、尺寸精度、外观质量优异的卷板原料，以提升焊管成型和焊接的质量。
Abstract:
In order to study the influence of hot-rolled steel coil quality on HFW welded pipe forming and welding, the influence of hot-rolled coil composition, microstructure, geometric dimension, appearance and longitudinal shear quality on HFW forming is analyzed. The results show that the composition, banded structure and inclusions of the coil directly affect the weldability and properties of HFW pipe. The width, thickness and other geometric dimensions of the coil not only affect the forming welding quality, but also affect the bead removal quality of the weld. The appearance defects such as the camber and wave bending of the coil affect welded pipe forming and welding stability, which is easy to lead to the occurrence of welding defects. The quality of longitudinal shear section of the steel coil also directly affects the quality of welding. In view of the above influencing factors, improvement measures are formulated from the aspects of coil smelting, rolling and longitudinal shear process, so as to provide coil raw materials with excellent weldability, purity, dimensional accuracy and appearance quality for high frequency welded pipe welding, and improve the quality of welded pipe forming and welding.
