Abstract

【課題】鋳片幅が大きな鋳片でも、鋳片の偏析発生を効果的に防止する。 【解決手段】矩形状の横断面を有する鋳片１を連続鋳造する際に、鋳片厚み中心部の中心固相率ｆSが少なくとも０．１～０．９の範囲を、鋳造方向長さ１m当たり、鋳片１の厚み方向の圧下率が１％以内となるようにして連続して軽圧下するとともに、該中心固相率ｆsが０．１～０．９の範囲内の少なくとも１箇所において、鋳片１の相対する両側の短辺面を、隣り合うピンチロール２ａ，２ｂ対間に配置した金型３を用いて、打撃振動周波数が４～１２Hz、振動エネルギーが３０～１５０Jで、鋳片幅方向に連続して打撃する装置である。 【効果】鋳片幅が大きな鋳片であっても、中心偏析やＶ偏析などの偏析の発生を効果的に防止し、内部品質の良好な鋳片を得ることができるようになる。
