在轧钢生产过程中,中板的宽度一般是靠圆盘剪来控制的。因此圆盘剪剪刃开口度调整的精度高低将直接影响到中板的剪切质量。这里所讲的剪切质量主要是指两个方面的问题:一是尺寸精度。按目前的国家标准,中板的宽度允许公差为+0～10mm,但要想使我们的产品在国际市场上有竞争力,就必须按国际标准组织生产。为此,新的国家标准将把中板的宽度公差定为+0～ In the rolling process, the width of the plate is usually controlled by the disc shears. Therefore, the opening degree of the disc shears edge adjustment accuracy will directly affect the shear quality of the plate. The quality of the cut mentioned here mainly refers to two aspects: First, the dimensional accuracy. According to the current national standard, the allowable tolerance of plate width is + 0 ~ 10mm, but in order to make our products competitive in the international market, we must produce according to international standards. To this end, the new national standard will set the width tolerance of the plate as + 0 ~
