摘要
为解决某厂转炉冶炼时出现操作氧压高、化渣困难、喷溅严重等问题,对其转炉氧枪喷头进行了结构优化改进,并建立起描述该喷头射流特性的数学模型,利用FLUENT软件对原喷头和改进后喷头的氧气射流进行了冷态数值模拟。结果表明:在距喷头相等距离上,改进后喷头的氧气射流速度明显降低,冲击面积增大。研究结果为下一步进行工业实验提供了坚实的理论基础。
In order to solve the problems such as high oxygen pressure, hard slag smelting and serious splashing, the structure of BOF lance nozzle is optimized and the mathematical model that describes oxygen jet characteristic is set up. The oxygen jet before and after the optimization is simulated by CFD software FLUENT in normal temperature condition. The result shows that jet velocity is reduced and cross-section area is enlarged after the nozzle optimization. This research provides strong basis for industrial experiment in theory.
