【摘要】 本文基于湍流时流理论，对多孔氧格喷头几何轴线上的速度分布特征进行了理论和实验研究．结果表明，多孔氧论喷头轴线上速度最大值的临界枪位可由下式计算并由大型喷头的实测结果得到了验证更多还原

【Abstract】 The characteristics of velocity distribution along the centerline of a multijetoxygen lance are studied by means of the turbulent jet theory. The critical lance height of themtalmum velocity along the cellterline of the multijet oxygen lance can be calculated withThis opation is in good agreement with a lot of experiments of multijet oxygen lances used forpractical BOF processes.更多还原
