中文摘要	The threedimensional flow field of molten steel in an 80ton single snorkel vacuum refining furnace has been mathematically simulated to attain the optimal configuration and operation parameters, such as the bottom blowing Ar flow rate, the eccentric position of bottom blowing Ar port at ladle bottom, the single snorkel inner diameter, and the single snorkel immersion depth into molten steel. The mathematical simulation results show that a stable flow field of molten steel can be achieved in 70second; meanwhile, the maximal circulation intensity of molten steel in the 80ton single snorkel vacuum refining furnace can be found on a crosssection with y as 0?mm based on the middle of ladle bottom as circular point of the Cartesian space coordinate under the condition of injecting Ar gas on x coordinate considering the asymmetry of flow field for molten steel in the single snorkel vacuum refining furnace. The recommended parameters of the 80ton single snorkel vacuum refining furnace with ideal circulation intensity as 970.1?kg/s are the bottom blowing Ar flow rate as 450500?Nl/min, the eccentric position of bottom blowing Ar port as 250?mm, the single snorkel inner diameter as 1000?mm, and the single snorkel immersion depth as 500?mm.
