PURPOSE:To uniformize supply of molten metal and to obtain a wide width thin slab by arranging plural flat nozzles along long side direction of a mold at the prescribed interval and also linear motors at least to the width covering the flat nozzle opening parts to the long side direction of the mold. CONSTITUTION:A flat mold 21 has one pair of facing endless casting belts 22 and one pair of facing short side molds 24 arranged between the endless casting belts 22, and the mold 21 is formed so that the side faces of the short side molds 24 are brought into contact with the belt faces. Then, the flat nozzles 1, 2 are arranged along the long side direction in the flat mold 21 at the prescribed interval. Further, the linear motors 5 have the width covering the opening parts of the flat nozzles 1, 2 to the long side direction of the mold. Therefore, the width of one piece of the flat nozzle becomes narrow and dent of the molten metal at center part of the nozzle becomes shallow. Further, the linears can do with only one pair of right and left sides and can be miniaturized. |
