摘　　要：搅拌功率是评估RH精炼炉技术优劣的一个重要指标,在提高渣-金反应速率以及去除夹杂物等方面有重大意义。以某钢厂180 t RH真空精炼炉为原型,在实验室以1:4比例建立水力学模型,探究RH真空精炼过程中不同浸入管浸入深度、真空室液面高度、吹气量对RH搅拌功率的影响。实验结果表明:搅拌功率与浸入深度呈线性关系:y=3.6817x-212.504;搅拌功率与真空室液面高度呈线性关系:y=26.256x-470.432;搅拌功率与吹气量呈线性关系:y=279.20565x-187.5418。As an important evaluation index for the refining technology of RH furnaces,mixing power has great significance in improving the slag-metal reaction rate and removing inclusions.In this paper,a 180 t RH vacuum refining furnace was taken as the prototype,and a hydraulic model was established at a ratio of 1:4,aiming to study the influences of immersion depth of the immersion tube,liquid level height of the vacuum chamber,and blowing volume on RH mixing power during RH vacuum refining.The experimental results show that the mixing power has a linear relationship with the immersion depth of the immersion tube:y=3.6817x-212.504;the mixing power has a linear relationship with the liquid level of the vacuum chamber:y=26.256x-470.432;the mixing power has a linear relationship with the blowing volume:y=279.20565x-187.5418.
