Abstract: In view of the requirements of large superconducting coils in the heat treatment process, it is necessary to ensure the temperature uniformity inside the furnace cavity in a large space and a long range. The multi-field coupling finite element analysis of the temperature field distribution and flow field state inside the heating system was carried out using 1/18 furnace cavitysimulation model. The prototypewas builtcombined with the analysis results, and the data collection and analysis of the temperature field of the heating system under actual working conditions were carried out. The results show that in the simulation model,the temperature uniformity of superconducting coil at 210 ℃ heating condition is within ±25 ℃, and the temperature uniformity of heat preservation condition is within ±5 ℃, meeting the temperature uniformity requirements. The test data and simulation data are consistent, which verifies the rationality of the design.

Key words: superconducting coil, heat treatment system, temperature uniformity, fluid-structure coupling, simulation analysis
