The contrast experiment of different stirring modes, which includes a new type of stirringinjection with the method of pulse and rotation, and the initial oneway stirring method, is done through physical simulation in the laboratory. The stirring methods of pulse and rotation are of two kinds. One is pulsed and rotary stirrer with positive and opposite directions. The other is pulsed and rotary stirrer with rotationstoprotation. The results show that the stirring mode of pulse and rotation has better effects than the oneway stirring method. The specific effects are that the mixing time of the melting bath is apparently shortened, the number of grains involved in the liquid surface is increased, and the residence time of air bubble in water is doubled.
