Abstract
【解決手段】 鋳型6の両短辺8側から浸漬ノズル11側に向かって移動する移動磁場を鋳型内の溶鋼1に印加し、浸漬ノズルから吐出される溶鋼の吐出流4に制動力を付与しながら鋳造する鋼の連続鋳造方法において、前記浸漬ノズルの吐出口の下端位置を、移動磁場印加装置13の鉄心の下端よりも上方に位置させると同時に、浸漬ノズルから吐出される吐出流の軌跡が移動磁場印加装置13の鉄心の設置位置の範囲を上下方向に逸脱しないように吐出角度を適正化した浸漬ノズルを用いて鋳造する。

- 鋳型の両短辺側から浸漬ノズル側に向かって移動する移動磁場を鋳型内の溶鋼に印加し、浸漬ノズルから吐出される溶鋼の吐出流に制動力を付与しながら鋳造する鋼の連続鋳造方法において、前記浸漬ノズルの吐出口の下端位置を、移動磁場印加装置の鉄心の下端よりも上方に位置させると同時に、浸漬ノズルの吐出角度を、上記の(1)式で定まる角度θD よりも上向きで且つ上記の(2)式で定まる角度θU よりも下向きの範囲内とすることを特徴とする鋼の連続鋳造方法。
θD :水平線を基準として下向きを正とし上向きを負とした、浸漬ノズルの吐出口の下端を起点として鋳片短辺位置での移動磁場印加装置の鉄心の下端位置までを測った角度(deg)
θU :水平線を基準として下向きを正とし上向きを負とした、浸漬ノズルの吐出口の下端を起点として鋳片短辺位置での移動磁場印加装置の鉄心の上端位置までを測った角度(deg)
H:移動磁場印加装置の鉄心の高さ(m)
Y1 :鋳型内湯面から浸漬ノズルの吐出口の下端までの距離(m)
Y2 :鋳型内湯面から移動磁場印加装置の鉄心の高さ方向中心位置までの距離(m)
W:鋳型の幅(m)
d:浸漬ノズルの吐出口部分における外径(m)
