摘    要:实验测量了电弧炉底部单喷嘴和多喷嘴喷吹的熔池水模型中混合时间和若干断面流场、混合时间随喷嘴直径、数量、位置及示踪剂投放点变化的函数关系。通过数值法求解了熔池流场及其混合过程。结果表明,仅靠增加喷嘴直径来改进熔池搅拌效果不显著。偏心、深熔池处布置的多喷嘴喷吹的流场混合能力较强,原因是这样布置使熔池流场具有较强烈的圆周方向对流并能获得更多的搅拌功率。

关 键 词:底吹电弧炉 混合过程 模拟 炼钢 电弧炉 溶池

Abstract:The flow field and the mixing time in the water model of the bath of bottom stirring electric arc furnace(EAF) for single-and multi-plug are numerically and experimentally studied. The mixing time is the function of the diameter, number, location of plugs and the tracer injection situation. It was shown that the variation of mixing time is not obvious with the increasing of plug diameter, the stirring efficiency is better if plug number is increased and plugs are distributed in deep and off-central region in vessel, since the angular velocities occur and the more stirring power is obtained in these layouts.
Keywords:bottom stirring electric are furnace   mixing time   numerical computation
