Abstract (en)

[origin: WO03049888A2] The invention relates to a method for producing a metal strip by continuously casting a molten bath between two casting cylinders (1, 2) of a continuous casting machine. According to said method, a surface current of the inclusions or impurities present on top of the bath is generated by injecting gas into the surface of the molten bath (4a). The injection of gas transports those inclusions or impurities laterally against the lateral seals (3). For this purpose, a device (25) is provided that has at least one gas channel (35, 36; 52) disposed above the surface of the molten bath (4a) and extending in the longitudinal direction of the casting cylinders (1, 2). Said channel has a number of outlet openings (46; 55) that are distributed across its entire length and that are directed downward at an angle and towards the next lateral seal (3). Said device makes it possible to keep the impurities from at least a larger part of the cast strip, thereby increasing purity of the strip.
