Electromagnetic metallurgy technology is an essential method of alloys production. Numerical simulation can help to optimize the process parameters of electromagnetic metallurgy process, and help to understand its internal mechanism. This article reviews the application of simulation technology in electromagnetic metallurgy in recent years. The calculation accuracy and efficiency of multiphysics solidification simulation methods in macro/meso-scale are compared. In order to help the further development and application of electromagnetic metallurgy technology, the possibility of extending the application physical scale of existing small-scale models is discussed.
