摘　　要：针对转炉活动烟罩在实际运行过程中集箱流量分配不均的问题,采用(CFD)数值模拟的方法,对影响受热管流量分布的集箱直径和集箱进出口方式进行不同工况下的数值模拟分析。模拟结果表明:随着集箱直径的增大,受热管流量分布的均匀性有显著提高;集箱直径D^(h)=209 mm的工况下集箱采用“下进下出”冷却水循环方式更符合受热管的理论配水需求。Aiming at the issue of uneven distribution of header flow of converter movable fume hood under actual operation,under different working conditions,the header’s diameter,inlet and outlet modes that influence flow distribution of heating pipe were analysed by(CFD)numerical simulation method.The simulation results show that the evenness of flow distribution of heating pipe is significantly improved with the increase of header diameter.The cooling water circulation mode“bottom-in and bottom-out”is more suitable for theoretical water distribution demand of heating pipe under working condition of header diameter 209 mm.
