摘要: 定義了評價軋機板形控制性能的六項指標,包括承載輥縫凸度調節域、輥縫橫向剛度、板形調控功效曲線、邊緣降、輥間接觸壓力平均幅值和輥間接觸壓力分布不均勻度.建立了HC,CVC,PC和DSR系列軋機的有限元仿真模型,并從板形控制性能的六項指標方面分析了當前國際上流行的各種機型的特點.Abstract: Six items were proposed for evaluating the shape control performances of a mill, including adjustable area and transversal stiffness of loaded roll gap, shape control efficacy curve, edge drop, average contact force between rollers, and its distribution ununiformity. The finite element models of several types of famous mills, such as HC, CVC, PC and DSR, were developed to calculate the roll. The deformation and control performances of these mills were analysed detailedly.
