摘　　要：以南钢30tLF精炼炉为研究对象,对钢包内的钢水流场进行了水模型实验研究。实验中用有机玻璃制成钢包,用水模拟钢水,压缩空气模拟氩气,采用的模型和原型比为0.74,在几何相似,同时保证模型与原型的修正佛罗德准数相等的前提下,以电导法测定了底吹氩钢包内钢液的混匀时间,对钢包不同吹氩位置的合理性进行分析和探讨,测定了不同位置、不同吹气量下钢包内的混匀时间,观察钢包内合金粒子的运动情况、死区情况、流场情况,得出偏心单吹的最佳偏心位置为0.55R处。Taking the 30tLF refining furnace of Nangang as the research object,a water model experiment was conducted on the molten steel flow field in the ladle.In the experiment,a ladle was made of plexiglass,molten steel was simulated with water,and argon gas was simulated with compressed air.The ratio of the model to the prototype was 0.74,which was geometrically similar and ensured that the modified Frode’s number of the model and the prototype were equal.Conductivity method measured the mixing time of molten steel in the bottom-blown argon ladle,analyzed and discussed the rationality of different argon blowing positions in the ladle,measured the mixing time in the ladle under different positions and different air blowing rates,and observed the alloy in the ladle According to the particle movement,dead zone,and flow field,the best eccentric position for eccentric single blowing is 0.55R.
