Abstract (en)
[origin: WO0191951A1] The invention relates to a method for the production of a continuously-cast precursor; in particular of wide slabs, with a precursor thickness D>100 mm and a precursor width B=2700 mm to 3500 mm at a casting speed vc<2 m/min in a continuous casting plant, a continuous casting plant for producing the above and a submerged outlet for the above. According to the invention, uniform solidification conditions for the cast strip and uniform melting and distribution conditions for the flux powder may be achieved, whereby the melt leaves the submerged outlet (6) through opposing exit openings (8), with a momentum towards the narrow side walls (4, 5) of the mould. For a particular width-thickness ratio of the precursor, depending on the ratio of the melt speed in the core cross-section of the submerged outlet (vk) to the casting speed (vc), design values for the width (b) of the submerged tube and the height (h) of the side openings of the submerged outlet are chosen such as to give a uniform strip shell formation in the direction of casting and circumferentially along the broad side walls (2, 3) and the narrow side walls of the mould.
