PROBLEM TO BE SOLVED: To provide a dual-drum type continuous casting apparatus capable of precisely adjusting a crown and a wedge of a metal thin strip, and manufacturing a high-quality metal thin strip with thickness distribution stable in a width direction.SOLUTION: A dual-drum type continuous casting apparatus has a first movement mechanism that moves at least one cooling drum 100A of a pair of cooling drums 100A, 100B in a direction orthogonal to the plate plane of the metal thin strip and a second movement mechanism that moves a pair of cooling drums 100A, 100B in a direction parallel to the plate plane of the metal thin strip, where the second movement mechanism comprises an intersection angle adjustment mechanism that adjusts the intersection angle of the rotary shaft of the pair of cooling drums 100A, 100B, an offset mechanism that adjusts the offset amount in casting directions of the pair of cooling drums 100A, 100B, and an offset control part that controls the offset amount in accordance with the intersection angle.SELECTED DRAWING: Figure 3 【課題】金属薄帯のクラウン及びウェッジを精度良く調整することができ、幅方向での厚み分布が安定した高品質な金属薄帯を製造することが可能な双ドラム式連続鋳造装置を提供する。【解決手段】一対の冷却ドラム１００Ａ、１００Ｂのうちの少なくとも一方の冷却ドラム１００Ａを前記金属薄帯の板面と直交する方向に移動させる第１移動機構と、一対の冷却ドラム１００Ａ、１００Ｂを前記金属薄帯の板面に平行な方向に移動させる第２移動機構と、を有し、前記第２移動機構は、一対の冷却ドラム１００Ａ、１００Ｂの回転軸の交差角を調整する交差角調整機構と、前記交差角を維持した状態で一対の冷却ドラム１００Ａ、１００Ｂの鋳造方向におけるオフセット量を調整するオフセット機構と、前記交差角に応じて前記オフセット量を制御するオフセット制御部と、を備えている。【選択図】図３
