三、带钢(钢板)的厚度不均带钢厚度不均是指下述两种:①带钢横向厚度不均;②带钢纵向断面厚度不均;带钢厚度不均的程度是衡量轧钢技术水平的重要标志。我厂经设备改造和技术队伍的培养,近十年来,厚度不均情况大有好转,见图15。1.带钢的横向厚度不均按其横断面形状可分为:中间厚度大于两边厚度、中间薄两边厚和一边厚一边薄三种。测其轧后带钢尺寸发现,多数带钢是中间厚两边薄,其原因如下:①原料横向厚度公差大,冷轧后不能
Third, the strip (steel) uneven thickness Uneven strip thickness refers to the following two: ① uneven horizontal strip thickness; ② strip longitudinal section of the uneven thickness; uneven strip thickness is a measure of rolling An important symbol of the level of technology. I plant by the transformation of equipment and technical team training, the past decade, the uneven thickness of the situation has greatly improved, shown in Figure 15.1. Uneven horizontal strip thickness according to its cross-sectional shape can be divided into: the middle thickness is greater than both sides of the thickness , The middle of the thin side of the thick and thin side of the thin three. Measured after rolling strip size found that the majority of the strip is thin on both sides of the thick, the following reasons: ① raw material horizontal thickness tolerance, can not be cold rolled
