Viscosity Properties of Mould Flux Under Low-Frequency Electromagnetic Field
The effects of magnetic field intensity, magnetic field frequency and Al2O3 content on the viscosity of molten slag in a low-frequency magnetic field were studied in this paper. The flow field of mould flux under low-frequency electromagnetic field was simulated by the finite element software. The experimental results showed that under the condition of this experiment, the magnetic field intensity increased from 0 to 30mT, and the viscosity of mould flux (1573 K) increased by 0.8–1.7 poise; the magnetic field frequency ranged from 6 to 12 Hz, and the viscosity(1573 K)increased by 0.9–1.6 poise; the content of Al2O3 increased from 3 to 7%, and the viscosity (1573 K) increased by 0.9–2.1 poise. Numerical simulation results showed that the flow field of mould flux is changed under low-frequency electromagnetic field, the amount of the slag in the disordered flow state increased and the viscosity increased.
