摘　　要：针对首秦公司LF炉由于氩气底吹位置布置不合理,造成LF炉精炼过程氩气流量无法实现精准控制的问题,利用FLUENT分析软件,建立了钢包底吹氩气模型,优化吹氩孔的位置。研究结果表明,吹氩孔位置距钢包中心由424 mm外移到711 mm,吹氩孔夹角由90°增大到122.4°,混匀时间减少126s,两相区流体动能增大,有利于能量的充分利用,加快粉剂的扩散和夹杂物的上浮。Due to the unreasonable arrangement of argon bottom blowing holes, the argon flow in the refining process of LF furnace can not be accurately controlled Shouqin Company. Ladle argon bottom blowing model is established by FLUENT software to optimize the placement of the argon - blowing holes. The result shows that if the distance between argon blowing hole and the ladle center is increased from 424 mm to 711 mm, the argon blowing hole angle is increased from 90°to 122.4° , the mixing time is reduced by 126 s, and so the luid kinetic energy of the two phase zone increases, which are beneficial to the full utilization of energy and accelerate the diffusion of powders and the floating of inclusions.
