Abstract

【課題】兼用コイル装置の内側と外側の巻き線の関係を最適化する。 【解決手段】電磁コイルに３相以上の交流電流又は直流電流を通電し、溶鋼に電磁攪拌又は電磁ブレーキを選択的に作用させる鋼の連続鋳造用電磁コイル装置である。電磁コイルは、ヨーク部１ａｂから２個のティース部１ａａを設ける。内側巻き線１ｂを施した２個のティース部１ａａのさらに外側に外側巻き線１ｃを施す。内側巻き線１ｂの巻き数を十分に巻ける場合は、外側巻き線１ｃの巻き数を内側巻き線１ｂの巻き数と等しくする。内側巻き線１ｂの巻き数が不足する場合は、内側巻き線１ｂの巻き数よりも多く、かつ２．５倍以下とする。この電磁コイルを各長辺１ａにｎ個（ｎは２以上の自然数）ずつ配置し、コア部１ａを溶鋼のメニスカス位置から浸漬ノズル４の吐出孔を含む鉛直方向の範囲に配置する。 【効果】内側巻き線を必要数巻けない場合も、十分な攪拌性能とブレーキ性能を確保できる。
