| 摘 要： | 基于流体模型和湍流修正模型,借助流体工程模拟软件Fluent 6.3.26对吹氩过程中210 t LF精炼炉盖内气体的流动、混合和质量、动量传输进行了计算模拟,分析了其流动行为和分布状态。结果表明,随钢包净空高度增加,液面上部氩气回旋区扩大,"死区"减小;当氩气流量增至500 L/min时,吹氩孔位于0.68 R的盖内流动效果优于0.3 R的效果;正常工作状态下的合理抽气压力为-150 Pa;在合理的抽气压力和吹氩孔位置的情况下,300 L/min的氩气流量基本可以满足要求,强搅拌时可增至500 L/min。

| Abstract: | Based on fluid model and turbulent correct model,the gas flow,mix and transmission of mass and momentum in 210 t ladle refining furnace lid has been simulated and calculated by using flow engineering simulation software Fluent 6.3.26 to analyze its flow behavior and distribution condition.Results show that with increasing the height of free board in ladle,the circulating region of Ar gas above liquid surface enlarges and thedead regiondecreases;as Ar flow rate increases to 500 L/min,the flow effect in lid w... |
