摘要/Abstract

摘要： 通过800mm高、熔池深度118mm的水模型模拟了转炉的复吹过程。使用不同粒度级别的渣滴分散出现频率与其尺寸级别的比例关系|M₈|参数和其空间分布均匀程度|K₈|参数,研究了操作条件对渣滴分散粒度及空间分布的影响,并得出经验公式。结果表明,在顶吹流量20～40m³/h和底吹流量0～1m³/h的情况下, 顶、底吹流量的增加有利于渣滴分散相的均匀分布。

Abstract: The converter combined blowing process was simulated by water model with 800 mm height and 118 mm bath depth. The effect of combined blowing operation parameters on size and space distribution of slag droplet dispersed phase has been studied by using parameter |M₈|- proportional relationship between frequency occurrence of dispersed phase and its size, and parameter |K₈|-degree of homogeneity of dispersed phase, and the concerned experimental formulas were got. Results showed that with top blowing rate 20 -40 m³/h and bottom blowing rate 0 〜1 m³/h, to increase top, bottom blowing rate was favourable for uniform distribution of slag droplet dispersed phase.
