Eliminating Surface Imperfection of High Frequency Welded Pipe by Optimizing Parameter Design of Squeeze Roller

  • 摘要: 分析高频焊管机组上挤压辊造成焊接管坯表面压痕、熔融金属压坑等缺欠的原因,并对上挤压辊进行调整和优化:通过增大上挤压辊孔型半径,增加了上挤压辊的“后跟隙”,有效地消除了焊接管坯表面的直线形压痕;通过减小挤压辊辊面宽度,增加了上挤压辊的辊缝,有效地消除了焊接管坯焊缝附近的焊瘤压坑。
    Abstract: Analyzed are the imperfection on the welded pipe surface such as indentation and molten metal pit,etc.as caused by the upper squeeze roll of the high-frequency welding pipe mill,and accordingly the upper squeeze roll of the pipe mill is properly adjusted and optimized.Relevant actions are taken,including enlarging the radium of the upper extrusion roll to get the“heel gap”thereof increased so as to obviously eliminate the line indentation on the pipe surface,and reducing the surface width of the said roll to enlarge the gap thereof so as to properly eliminate the overlap indented pit near the weld seam of the blank pipe.
