摘要
以40 t铝材退火炉内铝卷为研究对象,建立了铝卷退火过程的导热数值模型。为获得铝卷温度分布规律,采用ANSYS分析软件对铝卷温度场进行数值模拟,得到对流换热、接触热导等参数对铝卷退火的影响规律,并对仿真结果进行试验验证。结果表明,循环风机所引起的对流换热参数和铝卷捆扎力所关联的接触热导在合适数值范围内能提高铝卷退火各方面的质量和稳定性,且能缩短加热时间,降低成本。铝卷内外部温度计算值与试验值之间有较好的一致性。
The numerical value model of thermal conduction was established for annealing process of aluminium foil coils based on annealing furnace loaded with 40 t capacities. In order to obtain the temperature distribution of the coil,its temperature field was simulated numerically by use of ANSYS software. The influence of convection heat exchange and contact thermal conduction on coil annealing quality was gained, and the simulating results were experimentally verified. The results show that the appropriate convection heat exchange and contact heat conductivity relative to coil bundle up force can increase the coil annealing quality and stability in every aspect, and cut down the heating time and production cost. The calculation value of the coil inner and outer temperature coincides well with the test value.
