Mould flux is a vital functional material which was based on silicate including flux and framework material. The effects of magnetic field intensity and frequency on viscosity properties of mould flux were tested by rotational viscosity tester and a measurement device for electromagnetic characteristics of mould flux viscosity under high temperature conditions. The results show that: with the magnetic field intensity rising (0~30mT), the viscosity of mould flux increases by 1.3~1.8 poise. With the frequency rising (6~12Hz), the viscosity of mould flux is increased by 1.2~1.4 poise. When the binary alkalinity is 1.08, the viscous flow activation energy increases with the increase of the magnetic field intensity and frequency. It can be the main reason for the increase of mould flux that the electromagnetic forces disrupt the ordered structure of mould flux and make the iron rate increase.
