摘要： 以南京钢铁厂100 t圆筒形钢包炉为原型，根据相似原理建立水模拟系统，分别测定不同吹气位置和不同吹气量下钢包的搅拌效果，确定最佳参数，并与数值模拟结果比较. 结果表明，原型单双吹工艺搅拌效果都较理想，双吹工艺(透气砖位于底部0.57R处，双孔夹角为84o)效率更高，最佳底吹气量为350 L/min. 优化后钢包脱硫率提高了18.75%，钢包寿命延长了29.4%.

Abstract: On the basis of the similarity theory, a physical simulation system for 100 t cylinder ladle furnace (LF) of Nanjing Iron and Steel Company was established. Through changing the process parameters, the stirring effect of argon blowing from different positions in different flow rates was examined, the optimal bottom blowing positions and blowing rate were determined, and the numerical simulation was used to verify the optimized scheme. The results showed that the effects of prototypical single blowing and double plugs blowing are both relatively ideal, and two-hole (at the position of 0.57R with the angle of 84o) blowing effect is relatively better, and the optimal blowing rate is 350 L/min. After the implementation of the program, the desulfurization rate of LF was increased by 18.75%, and its working life was increased by 29.4%.
