The effect of highfrequencyelectromagneticfield imposed on outside of a cold crucible mold on the quality of cast metal in hot experiment was studied.
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。

Compared it with conventional billet, billet cast with highfrequencyelectromagneticfield, on which depth of surface oscillation mark was decreased remarkably, had a smooth surface.
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，且表面光滑。

For this reason, the antiscaling technology using highfrequencyelectromagneticfield is introduced. The application of this technology in Jiamusi no. 2 Power Plant etc. has seen good effect.
