基于Fluent烧结钕铁硼真空烧结炉气淬冷却温度场流场的模拟

Simulation of gas quenching cooling temperature field and flow field of sintered NdFeB vacuum sintering furnace based on Fluent

以SRVS-50G真空烧结炉为研究对象,基于Fluent有限元分析软件对烧结钕铁硼真空烧结炉气淬冷却过程温度场流场进行模拟分析。研究了冷却进风口风速和出风口数量对真空烧结炉冷却均匀性和冷却效率的影响,结果表明:提高进口风速可以提高冷却效率,但冷却均匀性降低,应该根据具体的产品温度均匀性要求选择适当的的进口风速,在出风口数量上,出风口数量为4,在冷却均匀性和冷却效率上都最佳。

Taking the SRVS-5oG vacuum sintering furnace as the research object,based on the Fluent finite element analysis software,the temperature field and flow field of the sintered NdFeB vacuum sintering furnace were simulated and analyzed during the gas quenching and cooling process.Effects of cooling inlet wind speed and outlet quantity on the cooling uniformity and cooling efficiency of vacuum sintering furnace were studied.The results show that increasing the inlet air speed can improve cooling efficiency,but the cooling uniformity is reduced.The appropriate inlet wind speed should be selected according to the specific product temperature uniformity requirements.In terms of the number of air outlets,the number of air outlets is 4,which is the best in terms of cooling uniformity and coolingefficiency.
