Abstract：The stirring power of hot metal by mechanical stirring method and magnesium injection method were calculated with empirical formula and plume model．The relationship between mixing time and stirring power of hot metal was determined according to the calculated results and compared with that of liquid in water model．The results show that mechanical stirring method stirring power is several times of the injection method stirring power．The mechanical stirring method mixing time is shorter than that of injection method at the same level of stirring power．The desulfurization rate of hot metal by mechanical stirring method is 18.61% higher than that by injection method．Meanwhile，it brings some negative effects which the temperature drop of hot metal caused by mechanical stirring method are 15℃ higher than that caused by injection method for strong mixing，and the refractory erosion rate of mechanical stirring method is 3 times of that of injection method．
