根据某钢厂热轧生产线实际需要和热轧地下卷取机能力不足的问题,建立了基于非线性有限元分析软件的地下卷取机有限元模型,对带钢卷取过程中的各卷取机构承载受力进行了动态仿真研究。以卷取新型号高强度带钢为例,通过带钢从夹送辊到卷筒的连续二维动态仿真,分析得到了夹送辊、卷筒、助卷辊的受力情况,从而对现有设备的承载能力进行评估,找到了承载能力不足的设备,并确定需求能力的大小,为即将增设的超强卷取机提供参考。 According to the actual needs of a hot rolling mill in a steel mill and the insufficient capacity of coiler in hot rolling, a finite element model of underground reeling machine based on nonlinear finite element analysis software is established. Mechanical load bearing dynamic simulation study. Taking the new type of high-strength steel strip as an example, through the continuous two-dimensional dynamic simulation of strip from pinch roll to reel, the force of pinch rollers, The carrying capacity of the equipment is evaluated, the equipment with insufficient carrying capacity is found, and the size of the required capacity is determined, which provides a reference for the upcoming super coiler.
