Abstract (en)

[origin: US2003150588A1] The invention relates to a process for producing slabs having a thickness D>100 mm, and at casting speeds v<3 m/min, in a continuous casting installation in which melt is supplied to a permanent mold from a storage reservoir via an immersion nozzle and from which, on the aperture side, a strand shell enclosing a liquid crater is withdrawn into a strand guidance frame, in particular a bow-type continuous casting installation. According to the invention, the melt supplied enters the permanent mold at a speed (vK) whose relationship with respect to the strand withdrawal speed (vB) is: vK:vB=6:1 to 60:1, and the flow filaments of the melt supplied are guided in such a way that, with regard to the melt level, they penetrate into the liquid crater over a length L<2 m over a wide front and with a profile which is rectangular in cross section. The invention furthermore relates to an appliance for producing slabs.
