Abstract

Abstract: With established argon bottom blown ladle three dimensional non-stable three-phase flow math model, Fluent software and Simple calculation method the shield slag flow characteristics during ladle refining process in bottom argon blown are studied and the effect of gas flow rate 200-3500 L/min of nozzle with diameter 0.1 m on slag eye size and slag layer flow behavior is analyzed. Results show that with increasing gas flow rate the slag eye enlarges and as argon flow rate is 400-2000 L/min the slag eye size and distribution of flow field in ladle are reasonable and available to refine； with increasing thickness of slag layer the slag eye range decreases but as the thickness of slag layer is more than 200 mm, the effect of thickness of slag layer on slag eye size is not obvious.

摘要： 通过建立的氩气底吹钢包三维非稳态三相流动数学模型以及Fluent软件和Simple算法研究了钢包精炼底吹氩过程保护渣的流动特性,并分析了喷嘴直径0.1 m时200~3500 L/min喷气量对渣眼尺寸、渣层运行的影响。结果表明,随喷气量增大渣眼增大,当氩气流量为400~2000 L/min时渣眼大小和钢包内流场分布较合理,有利于精炼;随渣层厚度增加,渣眼减小,但渣厚超过200 mm时,渣层厚度的增加对渣眼大小影响不显著。
