AbstractSoft-contact of molten steel can be achieved by applying a high-frequency electromagnetic field above the mold of continuous casting, which can effectively eliminate surface defects and achieve billets with no cracks and no oscillation marks. It also has some influence on the mold flux. In this study, the effect of a high-frequency electromagnetic field (20 kHz) on a mold flux flow field was simulated using a finite element software, and the slag film was extracted using a slag film simulator. The effect of the high-frequency magnetic field on the microstructure of the mold flux was analyzed using X-ray diffraction, Raman spectroscopy, and mineral phase testing. The results show that the high-frequency electromagnetic field disrupts the orderly movement and increases the movement rate of the liquid flux. The precipitate phase of the slag film did not change, but the silicate dimer Q1 decreased, the chain Q2 increased, and the network degree was increased. The slag film structure changed from the original two-layer form of crystalline layer–glass layer into a three-layer form of crystal layer–glass layer–crystal, and the crystallization ratio increased by 35% on average. The grain-size melilite granularity was reduced from the original 0.12 to 0.005 mm.

Flux Consumption

According to the rule of non-sinusoidal oscillation of continuous casting mold, a mathematical model was established to study the effects of oscillation parameters on the consumption rate of mold flux. The results indicated that the mold flux consumption rate is remarkably affected by the non-sinusoidal factor. This proves that the non-sinusoidal oscillation of mold contributes to increase the flux consumption. Moreover, the amplitude and frequency of mold oscillation have effects on mold flux consumption rate. The non-sinusoidal oscillation parameters must be optimized.
