带钢的拉伸弯曲矫直是提高质量的十分有效且获得广泛应用的方法,从酸洗线到镀锌线,在所有先进的带钢处理设备上均已采用。特别是这种方法可以完全消除或大大减少诸如不平、镰刀弯或一边薄一边厚等带钢缺陷。拉伸弯曲矫直是以较大张力,经往复几次弯曲,在带钢厚度上产生部分塑性变形,使带钢有一个不能恢复的延伸变形的方法。实际上,是带钢通过两组张力辊之间的所谓弯曲辊(图 Tensile bending straightening is a very effective and widely used method of improving quality, from pickling lines to galvanizing lines, and has been used on all advanced strip processing equipment. In particular, this method can eliminate or substantially reduce such thick strip defects as unevenness, sickles or thinner edges. Tensile bending straightening is a greater tension, the number of reciprocating bending, the thickness of the strip produced partial plastic deformation, the strip has an irreversible extension of the deformation method. In fact, it is the so-called bending roller that the strip passes between the two sets of tension rollers (Fig
