Abstract

The invention relates to a continuous-casting method for steel, in which molten metal is passed into a mould of rectangular cross-section from a tundish through an immersion nozzle. In order to make possible trouble-free operation in a continuous-casting plant for thin slabs, the invention proposes various measures, more particularly the automatic regulation and control of the casting-on process, the starting of strand withdrawal as a function of the liquid-metal level, the influencing of the strand withdrawal rate and of the liquid metal level in the mould and, finally, the changing of the position of the immersion nozzle as a function of casting parameters. <IMAGE>
