Abstract

A method and a device for producing steel strips by belt casting, wherein a molten metal is output from a feed vessel onto a circulating casting belt of a horizontal belt casting system under protective gas by a gutter and a siphon-like outlet area designed as a casting nozzle. At least one plasma jet, which renders the area of action inert and heats the area of action, influences the outlet-side area of the casting nozzle and the molten metal exiting therefrom at least during the casting process. For this purpose, at least one plasma torch, which produces a plasma jet and is directed at the outlet area of the casting nozzle in a direction opposite the casting direction, is provided.
