Abstract

Abstract:

Owing to the development of human society, higher quality metal materials are demanded. Cleanliness and homogenisation are typical goals of high-quality metal products. New opportunities for advances in material preparation technology are afforded by the development of physical science and technology. Recently, electric current pulses and pulsed magnetic fields have attracted significant attention in metal preparation owing to the high instantaneous energy and low circuit load afforded. Herein, the basic theory of electromagnetic effects in molten metals is first introduced. Subsequently, research status regarding the distributions of magnetic field, current, electromagnetic force, and corresponding flow fields in molten metals under applied electric current pulses and pulsed magnetic fields are presented and reviewed. Finally, studies and industrial applications of pulsed electromagnetic fields in metal cleaning and homogenisation are introduced.

Key words: electric current pulse, pulsed magnetic field, electric current, magnetic field, magnetic force, flow field
