To provide an electromagnetic brake device capable of properly reducing a downward flow velocity of molten steel throughout a width-direction area of a casting.SOLUTION: An electromagnetic brake device 100 is constituted so that the lengths of leading end surfaces P11 and P21 of iron cores 112 and 122 can go below those of base end surfaces P12 and P22 when the iron cores 112 and 122 are seen along a Z-axis direction and so that the X-axis direction length of the iron core 112 in a first position can be equal to or less than the X-axis direction length of the iron core 112 in a second position on the side of the base end surfaces P12 and P22 with respect to the first position when any position of the iron core 112 is set to be the first position.SELECTED DRAWING: Figure 1 【課題】 鋳型の幅方向の全体に亘って、溶鋼の下向きの流速を適切に低減することができる電磁ブレーキ装置を提供する。【解決手段】 鉄心１１２、１２２をＺ軸方向に沿って見た場合に、鉄心１１２、１２２の先端面Ｐ１１、Ｐ２１の長さが、基端面Ｐ１２、Ｐ２２の長さを下回り、且つ、鉄心１１２の何れの位置を第１の位置としても、当該第１の位置における、鉄心１１２のＸ軸方向の長さは、当該第１の位置よりも基端面Ｐ１２、Ｐ２２側の第２の位置における、鉄心１１２のＸ軸方向の長さ以下になるように電磁ブレーキ装置１００を構成する。【選択図】 図１
