Study on heating process of molybdenum particles in radio frequency plasma can provide theoretical guidelines for improving preparation process of plasma spheroidization. The effect of coil current frequency, position of injection probe tip and powder feeder rate on motion trajectories and heating process of molybdenum particles in plasma was studied by a numerical simulation method. The results show that molybdenum particles can be heated to higher temperature during the spheroidization process when coil current frequency is lower because of higher plasma temperature; Changing of injection pr...
