摘　　要：考察了冷坩埚式结晶器外施加高频电磁场对连铸坯表面质量的影响。研究结果表明 :采用在传统结晶器壁开缝的方法可以有效地提高型内的磁感应强度 ,而且结晶器内磁场分布基本均匀 ;施加高频电磁场的铸坯与传统连铸坯相比 ,表面振动痕深度明显减小 。The effect of high frequency electromagnetic field imposed on outside of a cold crucible mold on the quality of cast metal in hot experiment was studied.The experimental results showed that magnetic flux density in the divided mold was increased efficiently and the distribution of the electromagnetic field in it was basically equal.Compared it with conventional billet,billet cast with high frequency electromagnetic field,on which depth of surface oscillation mark was decreased remarkably,had a smooth surface.
