采用有限元的方法建立带钢立轧/平轧的三维模型,对热轧带钢粗轧过程的板廓的变化规律进行了仿真研究,重点分析了各道次轧制后带钢板廓形状和边角的位置变化,以及材质,立辊辊形,立轧压下量等因素对边角位置的影响。研究结论为现场解决热轧带钢表面的边部黑线缺陷问题提供了技术思路,为工厂最终解决此一表面缺陷提供了帮助。 The finite element method was used to establish the three-dimensional model of the strip rolling / flat rolling. The variation rule of the strip profile in the hot rolling strip rough rolling was simulated. The shape of strip profile after each pass was analyzed. The location of the corner changes, as well as material, vertical roller shape, the amount of vertical rolling pressure and other factors on the corner position. The conclusion of the study provides a technical idea for solving the problem of black line defects on the edge of the hot strip in the field and finally helps the factory to solve this surface defect finally.
