为了实现板坯在连铸连轧之间的宽度衔接,大侧压定宽技术是对板坯进行在线调宽的有效措施之一。在对武钢2250热连轧机的SP调宽压力机工作模式分析的基础上,利用大型有限元软件Marc建立了SP调宽压力机三维调宽有限元分析模型,分别分析了SP调宽压力机在调宽过程中板坯在长度、宽度和厚度方向的变形以及应力变化情况,为板坯宽度的精确调整提供了参考依据。
In order to achieve the slab in the continuous casting and rolling of the width of convergence, large-side pressure setting width is one of the effective measures to online slab widening. Based on the analysis of working mode of SP adjusting press with 2250 hot rolling mill of Wugang, the finite element analysis software Marc was used to establish a three-dimensional adjustable-width finite element model of SP adjusting press. The effects of SP adjusting width press on The width and thickness of the slab in the process of widening and the deformation of the slab and the stress changes provide the basis for accurate adjustment of the slab width.
