摘要
随着电磁热辊在电池极片轧制上的应用,电池极片的加工工艺、质量和效率得到了提高。但由于电磁热辊加热工艺的特殊性--转换过程中涉及多个物理场耦合,使其控制参数的确定和加热控制变的困难。通过研究电磁加热相关的理论,建立电磁热辊与之对应的数学模型,采用MATLAB软件和有限差分法对其加热过程进行仿真分析。研究了电磁热辊加热过程中的温度场的分布、变化规律及影响因素,确定了控制参数,为控制系统的设计提供了理论依据。
With the application of electromagnetic heating roller on battery pole piece rolling,the processing technology, quality and efficiency of the battery pole piece are improved. The special heating technology of electromagnetic heating roller which involves multi-physics coupling in the process of conversion makes it difficult to control the heating process and determine the control index. By studying the electromagnetic heating theory, the mathematical model of electromagnetic heating roller is established and the simulation and analysis of the electromagnetic heating roller using MATLAB software and the finite difference method are carried out. The distribution, change rule and influence factors of the temperature field in the heating process of the electromagnetic heating roller are studied and the control parameters are determined, and both of which provide the theoretical basis for the design of control system.
