摘要
以昆明理工大学真空冶金国家工程实验室氧化铝真空碳热还原炉为研究对象,依据传热学理论和氧化铝真空碳热还原炉的结构特点,分析了氧化铝真空碳热还原炉的加热和散热过程,并用有限元法建立了真空碳热还原炉瞬态温度场数值模拟计算模型,运用ANSYS软件对还原炉在持续加热下的瞬态温度场分布进行了数值模拟计算并得出了还原炉温度场的三维分布状况,同时分析了瞬态温度场的变化情况。经过具体实验验证,模拟计算结果与实验所测的局部各点测量值误差均在2%以内,实际所测的平均值与模拟结果误差在1%以内。
The 3-dimensional distributions of the transient temperature field,in the lab-built furnace dedicated to the vacuum alumina carbothermic reduction, were modeled based on finite element method, simulated with the software pack- age ANSYS, and experimentally estimated. In the simulation, the continuous temperature rising in the heating and dissipa- tion of heat was considered. The transient temperature distributions and the time evolution of the temperature field were al- so simulated. As compared to the test data, measured at the various key positions in the furnace with the platinum-rhodium thermocouples, the simulated results show a difference of less than 2%, and an average disagreement within 1%.
