摘要：

The effects of inductor structure, the positions of solid/liquid interface and melt top, and different alloys on the melt shape in electromagnetic contactless shaping process have been simulated by FEM method in the present paper. It is found that the inductor with an oblique inside wall makes the melt form an ideal vertical periphery. The position variation of solid/liquid interface and melt top can change the melt shape obviously. The electrical current frequency and the material kind have hardly effects on the melt shape. The experiment results have good agreements with the simulation results. Finally, some bars and plates of Al alloy, TiAl intermetallics and superalloy are produced in an unidirectional control of their structures by the contactless forming process.
