摘　　要：基于有限元数值分析,对不同搅拌风扇下可控气氛密封箱式炉内流场进行模拟,通过采用瞬态和稳态的方法,分析了4叶搅拌风扇(Fan4)和6叶搅拌风扇(Fan6)下可控气氛炉内部的流速、静压和动压变化趋势。Fan4炉腔内气流路径比较均匀,且都在炉腔上部非工作区域,Fan6炉腔内气流路径容易形成涡流,对炉温均匀性及气氛均匀性影响较大。Fan4和Fan6炉腔内动压云图基本上类似,工作区域内动压差别较小。Fan6炉膛内静压要普遍高于Fan4,同等条件下,6叶风扇会造成炉压偏高。Based on FEM numerical analysis,the flow field in atmosphere-controlled sealed box furnace with different stirring fans was simulated,and by using transient and steady-state methods,the flow velocity,static pressure and dynamic pressure changes inside the controlled atmosphere furnace were analyzed under the conditions of a four blade stirring fan(Fan4)and a six blade stirring fan(Fan6).The airflow path inside the Fan4 furnace is relatively uniform,and they are all located in the upper non-working area of the furnace.The airflow path inside the Fan6 furnace is prone to forming vortices,which have a significant impact on the uniformity of furnace temperature and atmosphere.The dynamic pressure cloud diagrams inside Fan4 and Fan6 furnaces are basically similar,and the difference in dynamic pressure within the working area is relatively small.The static pressure inside the Fan6 furnace is generally higher than that of Fan4,and under the same conditions,a six blade fan will cause the furnace pressure to be too high.
