Abstract

The invention relates to a casting nozzle for a horizontal strip casting system, especially for casting steel strip. The casting nozzle is connected to a feed channel and is designed as a rectangular refractory hollow block, the outlet region of which being only slightly above the cooled continuous belt which accommodates the outflowing melt. The hollow block is subdivided at least once in the direction of casting and a narrow sealing element is arranged on the partition side of the segments, the width of the remaining gaps in the partition area being selected as to close when the casting nozzle is operated.
