模拟了切缝式软接触电磁连铸结晶器的冷却效果及内部钢液的凝固。结果表明:感应热在铸坯纵向上主要集中在切缝对应的位置,在径向上主要集中在约5mm厚的铸坯表层;施加感应热后,结晶器出口的凝固坯壳厚度减小约0.5mm,说明感应加热对铸坯冷却效果影响不大;高频磁场产生的感应热使结晶器热面温度提高了6K,结晶器冷面温度提高了3K,不会对结晶器的耐热强度造成较大的影响。
The cooling effect of the slotted soft contact electromagnetic continuous casting mold and the solidification of the internal molten steel are simulated. The results show that the induction heat mainly concentrates in the longitudinal direction of the slab at the position corresponding to the kerf and is mainly concentrated in the radial direction on the slab surface of about 5 mm thick. After the induction heat is applied, the thickness of the solidified shell at the outlet of the crystallizer decreases by about 0.5 mm, indicating that the induction heating has little effect on the cooling effect of the billet; the induction heat generated by the high-frequency magnetic field increases the hot surface temperature of the mold by 6K and the cold-surface temperature of the mold by 3K, which does not cause the heat resistance of the mold Greater impact.
