摘　　要：对莱钢型钢炼钢厂140 t RH精炼炉进行水力学物理模拟。主要从RH装置内液体流动行为、混匀时间和夹杂物去除过程等方面进行实验和研究。结果表明：在RH精炼初期,为防止喷溅RH提升气量应控制在60-70 Nm^3/h,而后为获得较快的传质速度来加速脱碳并使RH有较好的混匀效果,提升气体流量应控制在90 Nm^3/h;后期为获得较好的去夹杂效果应采用60 Nm^3/h的提升气量,浸渍管的浸渍深度应控制在500 mm。The hydraulics physical simulation for 140 tons of RH refining furnace in the steelmaking plant of Laigang Section Steel Co.,Ltd. was carried out in the paper,and the experiment and research were mainly from the aspects of liquid flow behavior,blending time and inclusion removal process in RH device. The results showed that,at the beginning of RH refining,in order to prevent splashing,RH ascending gas should be controlled within 60 Nm^3/ h - 70 Nm^3/ h; after that,in order to achieve a faster mass transfer speed to accelerate the decarburization and get a good blending effect for RH,the ascending gas should be controlled at 90 Nm^3/ h; in the later stage,the the ascending gas should be controlled at 60 Nm^3/ h to get a good inclusion removal effect; and the dipping depth of soaking tub should be controlled at 500 mm.
