PROBLEM TO BE SOLVED: To prevent the falling of a castable in the top end part and a top lining brick of a ladle, and to prevent the horizontal opening of a joint in the lining brick. SOLUTION: In a ladle where lining bricks 3 are applied to the inside of an iron shell 1, a sheet-shaped vertical rib 10 with a length to the upper part of the top lining brick 3A is set inside the upper end part of the iron shell 1 toward the center of the ladle in the circumferential direction at a prescribed interval. The space between the inner end of the vertical rib 10 and the top lining brick 3A is provided with a gap allowing the expansion of the lining brick 3A to provide parallel arrangement. The upper part of the vertical rib 10 and the top lining brick 3A including the gap is filled with a castable 4. COPYRIGHT: (C)2004,JPO
