On the basis ofexperimental results, the flow boundary conditions of liquid metal at the slag-metalinterface of a gas injecting bath were deduced. The flow field and the turbulent pa-ramaters of the metal bath covered with slag were solved by the vorticity-streamfundion method. Results reveal that the flow velocity, turbulent energy and circulat-ing rate of the melt under slag are lower than that of without slag cover. Anotherone "dead zone" of the lowest turbulent energy is formed in the top layer underthe cover of slag near the ladle linnng.
