Study on the Magnetocaloric Effect of Molten Mold Flux Under Low-Frequency Electromagnetic Field

Numerical simulation was used to study the magneto-Joule heating effect of molten mold fluxMolten mold fluxes under a low-frequency electromagnetic fieldLow-frequency electromagnetic field in continuous castingContinuous casting. The effects of electromagnetic field parameters on the conductivity of molten mold fluxMolten mold fluxes were also investigated. The results showed that the induced current and magnetic induction in molten mold fluxMolten mold fluxes increased with its increasing conductivity and excitation current, and the magneto-induced Joule heatJoule heat also increased. The magneto-Joule heatJoule heat was found around 0.97 × 103 to 6.29 × 103 J m−3. For every 10 mm decrease from the magnetic field action center, the Joule heatJoule heat of molten mold fluxMolten mold fluxes increased 11.8% on average. A greater conductivity of the mold flux resulted in a more significant change in Joule heatJoule heat.
