Key words: tundish; slot plug; gas-liquid two-phase flow; mathematical simulation Abstract: Slot plug used for bottom power injection was applied at tundish． The distributions of the volume percentage of the gas and flow field at tundish were studied． The results show that seam width and the gas flow have a significant influence on the forming of gas curtain; the flow characteristics of molten steel was better when the gas flow rate was 10 m3 /h．
