Research on Gas-liquid Flow Characteristics During RH Vacuum Refining Process
RH vacuum refining plays an important role in the production of low-carbon steel.The gas-liquid flow characteristics of the refining process are explored by the numerical simulation methods.The results indicate that the fluid velocity agrees well with the measured data from experiment.The distribution of argon bubbles in up snorkel shows an inverted V shape,and the proportion of Ar-liquid steel two-phase zone increases to 74.93%when it is 3.7 meters from the bottom of the ladle.The flow velocity near the up snorkel reaches its maximum value of 1.2 m/s.
