Abstract：The numerical simulation method was used to study the influence of the number of nozzles, the flow rate and the position of bottom blowing on the flow field in the molten pool. The results show that by using four nozzles to control the bottom blowing flow rate of 1.14 m·s-1, a good flow field with short mixing time and uniform composition can be obtained. When the size of molten pool is larger, the blow flow field near the bottom has little effect.
