Numerical simulation and optimization of temperature field of sintered NdFeB vacuum furnace based on fluent
Taking the SRVS-300G vacuum furnace as the modeling research object,Fluent analysis software and S2S radiation model were used to simulate and analyze the temperature field of the vacuum furnace insulation state.The simulation results were compared with the measured data at monitoring points,with a maximum error of 2.56％.On this basis,further research is conducted on the temperature field distribution under load conditions,and the fur-nace structure is optimized for design.The results showed that under the load state of the SRVS-300G vacuum fur-nace,the temperature of the middle part of the workpiece was lower,and the temperature uniformity of workpieces closer to the base is worse than that of workpieces closer to the upper part.The temperature of the workpiece near the inner side of the furnace was slightly higher than that near the furnace mouth,and the temperature of the workpiece closer to the middle was lower.The temperature of the workpiece closer to the inner side was slightly lower than that of the workpiece on the edge.Appropriately increasing the width of the heating element can improve the heating uniformity.
