【摘要】 介绍了磁场分类及其在材料凝固技术中的应用研究现状。磁场可分为稳态磁场和非稳态磁场,其中稳态磁场又可分为尖角磁场(CMF)、垂直磁场(VMF)、水平磁场(HMF);非稳态磁场可分为旋转磁场(RMF)、行波磁场(TMF)、脉动、脉冲、交变磁场(AMF、PMF)和复合电场磁场(EMF),同时具体阐述了每种磁场的机理及其在材料凝固技术中的应用情况。最后对未来的电磁凝固技术进行了展望。更多还原

【Abstract】 Various types of magnetic fields in solidification and their application are introduced,and their main pros ans cons for solidification process are discussed.There are two main kinds of magnetic fields used in solidification:steady magnetic fields and non-steady magnetic fields.The steady magnetic field includes cusp magnetic field(CMF),vertical magnetic field(VMF) and horizontal magnetic field(HMF),while the non-steady magnetic field includes rotating magnetic field(RMF),traveling magnetic field(TMF),alternating(pulsating) magnetic field(AMF,PMF) and eletromagnetic field(EMF).The prosperous future of the magnetic field process is expected.更多还原
