| Abstract: | Induction melting and electromagnetic shaping for liquid metal are a material processing technique without mould (or crucible), which has advantages of no contamination and short cycle processing. The principle and characteristics of some typical methods of induction melting and electromagnetic shaping were discussed. The trends of developments of those induction melting and electromagnetic shaping techniques were also prospected. Electromagnetic shaping and directional solidification integrates melting of metal, no contact electromagnetic shaping of melt and controlling of solidification structure. It is considered to be suitable for shaping special alloys which are high melting-point, oxidizable and liable to react against mould material. |
