摘要
根据直缝焊管变形规律,以生产102 mm×4 mm直缝焊管和100 mm×80 mm×4 mm矩形管的轧辊孔型设计为例,介绍了短成型机组的构成和各种优点及轧辊的设计方法。通过精确的计算,得出了各成型架次的孔型尺寸,实现了焊管轧辊的设计。生产结果表明,该设计方法减小了对带钢中部的约束,使中间成型段自然成型,降低了轧制摩擦,提高了成品管表面质量,可有效地降低辊耗。与W成型法相比,具有明显的优势。
According to deformation rule of longitudinal welded pipe, taking an example of roll pass design for production φ102 mm×4 mm longitudinal welded pipe and 100 mm×80 mm×4 mm rectangular tube, it introduced the structure, various advantages , as well roller design method of short forming unit. The groove size of each forming frame was got through refined calculation, and roller design of welded pipe was realized. The production result showed that the proposed design method decreased constraint to the middle of strip steel, made the middle forming section form naturally, reduced the rolling friction, improved surface quality of the finished product, and lower the roller consumption effectively. Compared with W forming method, the mentioned forming method is with obvious advantages.
