Abstract (en)
[origin: EP2140956A1] The pouring device comprises an inlet opening (31) and an outlet opening (32) for molten metal, and a flow path (27) for the molten metal formed between the inlet and outlet openings. The flow path is formed by a path (33) around 180[deg] C. An entrance area (5) downstream to the inlet opening is intended in the device and the entrance area comprises a large cross-section as the inlet opening. The device has a cross sectional area, which has a respective cross-section as the preceded cross sectional area. The pouring device comprises an inlet opening (31) and an outlet opening (32) for molten metal, and a flow path (27) for the molten metal formed between the inlet and outlet openings. The flow path is formed by a path (33) around 180[deg] C. An entrance area (5) downstream to the inlet opening is intended in the device and the entrance area comprises a large cross-section as the inlet opening. The device has a cross sectional area, which has a respective cross-section as the preceded cross sectional area. The cross-section area has an equally large or small cross-section than the preceded cross-section area. An interior wall of the pouring device has bumps. The flow path is partially filled with polystyrene and a filter is arranged in the flow path. A reducer is arranged in the outlet opening and the pouring device is formed together from fireclay component. The pouring device is formed from incombustible mass, ramming mixture, core sand and/or molding sand.
