PURIFYING MOLTEN METAL |
摘要 |
The invention relates to a means of purifying molten metal, particularly steel, by the removal of impurities/inclusions during continuous casting. The molten metal (3) is passed in a tundish (1) through an array of vertical baffles (8) that are spaced apart transversely across the tundish to provide restricted flow channels (12). The baffles (8) may be flat boards or tiles (9a,9b) and are preferably used in contact with a weir (7) and dam (10), upstream and downstream respectively of the baffles. The speed and direction of flow of the molten metal can thereby be controlled and directed to give more effective dwell time in contact with a surface covering layer (11) of flux.
