- 磁場の移動方向が鋳型幅方向である移動磁場発生装置を用い、長辺及び短辺を有する矩形状鋳型の中央部に設置された浸漬ノズルから吐出される溶鋼に、鋳型短辺側から浸漬ノズル側に向かう移動磁場を印加して、鋳型短辺から鋳型幅の1/4だけ離れた位置における溶鋼湯面の表面流速が絶対値で0.05m/秒以下になるように鋳型内の溶鋼流動を制御しながら鋳造する鋼の連続鋳造方法であって、前記移動磁場は、移動磁場の周波数の下限値が、浸漬ノズルの吐出孔からの吐出流が磁場作用域を通過する間に少なくとも移動磁場の作用を1周期以上受ける周波数であり、且つ、移動磁場の周波数の上限値が、浸漬ノズルの吐出孔からの吐出流が吐出孔から鋳型長辺幅×1/2の1/3の距離の位置まで鋳型短辺方向に広がるまでに移動磁場の作用を1周期以上受けない範囲内であって、下記の(1)式を満たす範囲内の周波数であることを特徴とする、鋼の連続鋳造方法。
f<(3u)/(2L) …(1)
但し、(1)式において、fは移動磁場の周波数(Hz)、uは浸漬ノズルからの溶鋼吐出流の代表流速(m/秒)、Lは鋳型中心から鋳型短辺までの距離(m)である。
