To study the vacuum arc remelting process by means of computer simulation technology has gradually grown into a new trend. This method not only helps to ascertain the influences and mechanism of various technological parameters on the vacuum arc remelting process, but also can effectively predict the stability of the remelting process as well as the metallurgical quality of the ingot. Hence, the development history and the scientific research findings of the numerical simulation of the vacuum arc remelting process in the past 30 years were briefly introduced. Meanwhile, the research progress and the application status of the vacuum arc remelting model, the metal molten pool model and the microstructure model were reviewed in detail by taking the smelting process simulation, the macroscale simulation and the micro-scale simulation as the breakthrough point. Finally, a new development direction was proposed for the further development and application of numerical simulation of the vacuum arc remelting process in China.
