Abstract

【課題】兼用コイルへの電流の印加態様を具体化する。 【解決手段】２個の磁極鉄芯５ａ夫々の外周部に巻き回した２個の励磁コイル５ｂと、２個の磁極鉄芯５ａを合わせた外周部に巻き回した１個の励磁コイル５ｃを有する電磁コイルを、鋳型３の各長辺３ｂの外周に同じ個数、長辺３ｂの外周合計で（２ｎ＋２）個（ｎは自然数）配置する。電磁攪拌の場合は、全ての電磁コイルの各励磁コイル５ｂ，５ｃに、電流位相差が９０度から１２０度の３相以上の多相交流電流を通電する。電磁ブレーキの場合は、各電磁コイル当たり、前記励磁コイル５ｃまたは３個の励磁コイル５ｂ，５ｃに直流電流を通電して鋼を連続鋳造する。鋳型３に給湯する溶鋼２の成分組成と給湯量に対応させて、電磁ブレーキまたは電磁攪拌を選択的に作用させる。 【効果】鋼種や鋳造条件によらず、表面品質の良好な鋳片を安定して得られると共に、ブレークアウトの発生を抑制できて安定した操業が可能になる。
