Research on the Temperature Uniformity of Vacuum Furnace and Size Optimization of Working Zone

According to the radiation heating technology, a simulation model of temperature field in vacuum furnace's heating chamber is established. To realize the control standards for the temperature uniformity in furnace, thermocouples were arranged according to the nine point method. Due to the complex structure in vacuum furnace, a numerical simulation software ANSYS was chosen for modeling and analysis. Finally, on the condition of keeping the fixed outer wall size and good temperature uniformity, this paper optimized the size of working zone and obtained the maximum.
