Abstract (en)
[origin: EP2380682A2] The water-cooled lid (10) comprises two sub-elements, a flange (12) part element formed by sub-elements, an inner wall, cooling channels (15), and a central opening, where a lance is inserted through the opening of an inner wall of the treatment vessel. The lid is formed like a dome, where the ratio of internal clear height to inner light diameter of a flange of the lid is 0.2. The inner wall of lid facing the side of the molten metal is smooth and crease-free, and is formed without a gap. The cooling channels are arranged on outside of the inner wall. The water-cooled lid (10) comprises two sub-elements, a flange (12) part element formed by sub-elements, an inner wall, cooling channels (15), and a central opening, where a lance is inserted through the opening of an inner wall of the treatment vessel. The lid is formed like a dome, where the ratio of internal clear height to inner light diameter of a flange of the lid is 0.2. The inner wall of lid facing the side of the molten metal is smooth and crease-free, and is formed without a gap. The cooling channels are arranged on outside of the inner wall, where the surface temperature of the inner wall is 350[deg] C. The inner wall consists of sheet steel and copper. Cooling elements are applied on the existing copper sheet steel inner wall.
