摘　　要：研究铝合金连续铸轧的前箱及铸嘴型腔流体的有限元热分析方案的合理性评价标准;采用通用有限元计算软件AN-SYS/FLOTRAN模块的流热耦合建立温度场分析模型;应用MATLAB软件对结果数据进行了深入分析,以现场实验的数据为依据,建立并比较了两种模拟工况的温度场模型的分析结果,定量讨论了有限元计算的出口温度的绝对误差、相对误差,得出了温度场有限元计算的许用不均匀度.图5,表1,参11.Aim to explore the computation standards for finite dement analysis of thermal analysis of the fluid fidds of the front-box and the nozzle-shaped space of aluminum roll-casting; The computation was performed by using coupled fluid-thermal FEM simulation of the FLOTRAN module of the general finite dement analysis software, ANSYS. Pestprocesalng by Ansys and stricter analysis of results by software MATLAB was reviewed. The allowable inhomogeneity and its applicabilities of temperature of outlet for thermal field finite dement analysis were rendered down from observations and recorded data of two industry experiments in reality.5figs., ltab., 1 lrefs.
