a.亮带多数出现在较薄规格的带钢上,在小于3.5mm的带钢表面易出现亮带,且厚度越小,卷重越大,亮带的长度和亮度就越大,并且越靠近带钢尾部亮度越大。b.亮带在带钢上下表面同时出现,且位置和数量均相互对应。c.当亮带出现时,往往在成品卷外表面上能看到明显的周向凸起,此处的卷径要比 a. The majority of bright bands appear on the thinner gauge strip, bright bands appear on the strip surface less than 3.5mm, and the smaller the thickness, the larger the roll weight, the greater the length and brightness of the bright band, and the more Brightness near the rear of the strip increases. b. bright belt in the strip at the same time appear on the lower surface, and the location and the number of each correspond to each other. c. When the bright band appears, it is often seen on the outer surface of the finished roll with a clear circumferential bulge, where the coil diameter is greater than
