During ladle refining process, argon gas is purged into the ladle for stirring the molten steel bath to eliminate thermal and composition gradients and to achieve inclusion flotation. Operating parameters like purging location, porous plug configuration and argon flow rate primarily affect liquid steel refining. The efficiency of ladle processing is often quantified through mixing time. To optimize the mixing time and the associated process parameters for improved bath homogenization and inclusion flotation under different operating conditions, water modeling studies using 0.2 scale perspex model and computational fluid dynamics studies using ANSYS CFX v14.5 have been carried out through fluid profile assessment and mixing time comparison. Comparative study was made between single plug, dual plug and top lance purging configurations. The studies helped in identifying the optimum argon purging rates and configurations under normal operational practices. Under abnormal operating conditions involving purging failure from either of the two porous plugs, usage of a top lance along with the single working porous plug has been investigated and found to improve mixing and inclusion flotation in the ladle equivalent to dual plug operation. The lab scale studies have been validated on plant scale through inclusion mapping and found to be in close agreement.

在钢包精炼过程中，将氩气吹入钢包中以搅拌钢水，以消除热梯度和成分梯度，实现夹杂物的浮选。吹扫位置、多孔塞配置和氩气流速等操作参数主要影响钢水精炼。钢包加工的效率通常通过混合时间来量化。为了优化混合时间和相关工艺参数，以在不同操作条件下改善熔池均质化和夹杂物浮选，使用 0.2 比例有机玻璃模型的水建模研究和使用 ANSYS CFX v14.5 的计算流体动力学研究已通过流体剖面评估和混合时间比较。对单塞、双塞和顶喷枪吹扫配置进行了比较研究。这些研究有助于确定正常操作实践下的最佳氩气吹扫速率和配置。在涉及从两个多孔塞中的任何一个吹扫失败的异常操作条件下，已经研究了顶部喷枪与单一工作多孔塞的使用，并且发现与双塞操作等效地改善钢包中的混合和夹杂物浮选。实验室规模的研究已经通过包含映射在工厂规模上得到验证，并且发现非常一致。已经研究了顶部喷枪和单一工作多孔塞的使用，发现与双塞操作等效，可以改善钢包中的混合和夹杂物浮选。实验室规模的研究已经通过包含映射在工厂规模上得到验证，并且发现非常一致。已经研究了顶部喷枪和单一工作多孔塞的使用，发现与双塞操作等效，可以改善钢包中的混合和夹杂物浮选。实验室规模的研究已经通过包含映射在工厂规模上得到验证，并且发现非常一致。
