基于有限元分析的中间坯温度预报策略
Temperature prediction strategy of intermediate slabs based on finite element method
摘要
Abstract
During the transport process, the heat transfer boundary conditions between the upper and lower surfaces of the intermediate slab are different, so there exist certain differences in the surface temperature drop process, and the prediction of the finishing entrance temperature will be influenced, as well as the set-up model precision. In order to enhance the model precision, the heat transfer process was analyzed systematically by the finite element method, and on the basis of the analysis, the impact of residence time, initial temperature and the strip thickness on the surface temperature were obtained. The mathematical description of the surface temperature were obtained by fitting, and the average temperature prediction model was optimized. The results show that the predicted precision of the optimized model can meet the actual control requirements effectively.关键词
