Study on the Influence of Low-Frequency Electromagnetic Field on the Absorption Rate of Al2O3 Inclusion in Low Reactivity Mold Flux

With the wide application of electromagnetic stirring in continuous casting and the rapid development of low reactive mold fluxMold flux, the effect of low-frequency electromagnetic fieldLow-frequency electromagnetic field on the assimilation and absorption rate of Al2O3 inclusionAlO inclusion in the low reactive mold fluxMold flux was studied by using the rotating cylinder method, and the relationship between electromagnetic field parameters and the dissolution rate of Al2O3 inclusionAlO inclusion was also studied. The results show that the low-frequency electromagnetic fieldLow-frequency electromagnetic field can obviously promote the assimilation and absorption of Al2O3 inclusionInclusions in low reactivity mold fluxLow reactivity mold flux. When the magnetic field intensity (MFI) is 30 mT and the magnetic field frequency (MFF) is 12 Hz, the maximum dissolution rate of Al2O3 inclusionAlO inclusion is 2.66 × 10–4 g mm−2min−1, which is 10.64 times higher than in the absence of magnetic field. Furthermore, the higher the MFI and MFF, the faster the dissolution rate of Al2O3 inclusionAlO inclusion.
