Abstract

Metal strip close to its final dimensions is cast using a strip-casting apparatus provided with a melt-holding vessel and a conveyor belt, in which a metal melt, in particular steel, flows out of a casting nozzle of a closable pouring chamber which can be put under vacuum and is connected via a siphon to a main chamber which can be put under pressure. The casting nozzle is inclined by about 45.degree. and is of trumpet-like configuration in the region of the orifice on the inside of the nozzle wall remote from the main chamber. Additionally, a shut-off element which can be opened in a slit-shaped manner is provided near the orifice of the casting nozzle.
