摘要: 采用几何相似比1:4.5的水模型对150 t钢包底吹氩的工艺参数进行模拟试验,研究了喷孔圆周(0.40~0.70 R)、同圆周夹角(60°~120°)流量(189~378 L/h)对混匀时间的影响,测定吹氩流量与表面流速的关系以及分析了不同流量下的卷渣现象。结果表明,最佳的底吹方案是120°夹角,0.7 R双孔同圆周,流量378 L/h(对应实际流量600 L/min);最佳喂线位置为0.4 R;软吹时临界卷渣流量为110 L/h(对应实际流量175 L/min)。

Abstract: The simulation test on process parameters for an 150 t ladle bottom argon blowing with geometric simularity ratio 1: 4. 5 water model has been carried out to study the effect of blowing nozzle circle (0. 40 ~0. 70 R) , angle of nozzle at same circle (60° ~ 120°) and flow rate ( 189 ~378 L/h) on mixing time, define the relationship between argon flow rate and surface gas velocity and analyze on slag entrapment phenomena at different flow rate. Results show that the parameters of optimum bottom argon blowing scheme are angle 120°, 0. 7 R double nozzle at same circle and blowing flow rate 378 L/h (corresponding to real flow rate 600 L/min) ; the optimum wire feeding location is at 0. 4R; and in soft blowing the critical slag entrapment bottom flow rate is 110 L/h (corresponding to real flow rate 175 L/min).
