Abstract This paper mainly does the following researches with the object of argon bubble in the process of the blowing argon from the bottom of ladle. The VOF numerical simulation was used to track the interface of argon gas and the liquid steel. Three-dimensional numerical simulation method is used to simulate the bubble generation and movement under laminar condition. Using the Tecplot to analyze the post-processing of simulation results， the influence of different gas flow conditions on the bubble diameter and movement characters was investigated. Simulation results show that the bubble formation consists of two stages，that are expansion and detachment. The departure diameter of bubble increases with the increase of the gas flow rate. The upper limit of the bubbling regime is 1.325 L/min for nozzle with 2 mm diameter. The bubble shape is changed with approximate spherical，flat elliptical spherical，regular spherical and irregular spherical cap. The deformational degree of bubble increases with increasing the gas flow rate. All of bubbles present approximate spherical when located in the upper position of ladle height and do not change with the flow rate.
