通过实验俭测和数值模拟方法研究结晶器切缝形式、弯月面位置以及感应线圈匝数等因素对方坯软接触电磁连铸结晶器内高频磁场分布的影响．分析结果表明：采用通体切缝形式的结晶器具有比封闭切缝形式结晶器更好的透磁性；增加感应线圈匝数时，可增大高频磁场在铸坯初始凝固区的有效作用范围：当液态金属弯月面位于感应线圈上沿附近时，高频磁场作用于初始凝固区的有效作用范围较大、电磁压力分布的不均匀程度较小，有助于获得高表面质量的铸坯．通过拉坯实验获得了表面质量得到明显改善的 Ｓｎ—１０Ｐｈ合金铸坯．
The effect of mold slit form, meniscus position and number of turns of induction coil on high frequency magnetic field distribution in billet soft contact electromagnetic continuous casting mold was studied by means of experiment and numerical simulation. The analysis results show that the mold with through-body kerf has better permeability than the mold with closed kerf and the effective range of high-frequency magnetic field in the initial solidification zone can be increased when the number of turns of the induction coil is increased: When the liquid metal meniscus is located in the vicinity of the induction coil, the effective range of high-frequency magnetic field acting on the initial solidification zone is large, and the distribution of electromagnetic pressure is less uneven, which helps to obtain the slab with high surface quality. Sn-10Ph alloy slab with obviously improved surface quality was obtained through the drawing experiment.
