【摘要】 通过实测数据及理论参数建立了ＲＨ环流和主要影响因素间的应用关系，计算结果与工业试验数据相吻合。定量分析了顶吹方法对ＲＨ 环流过程钢包所获得的单位搅拌功率的影响。结果表明，顶吹氧射流对钢包混匀时间和循环流量的作用可以忽略。更多还原

【Abstract】 A model describing relationship among major factors and RH circulation flow rate was established by measuring parameters and theoretical calculation.The calculated results were in accordance with the data measured in industrial tests and water model experiment.The effect of top blowing on the unit stirring power obtained in the ladle in RH circulating process was analyzed quantitatively by using this model.The result shows that the effect of top blowing oxygen jet on the mixing time and circulation flow rate can be disregarded.更多还原
