Abstract
A slab nozzle for use in a continuous slab casting installation is characterized by a specific geometry of the outer wall of a downstream portion thereof which is inserted in a slab mould cavity. The specific geometry promotes a 'round-about' effect whereby converging opposite streams of molten metal flowing towards two opposite flanks of the slab nozzle are each preferentially deviated towards one side of the slab nozzle where they can freely flow through the narrow channels formed between the slab nozzle and the slab mould cavity wall without impinging with one another. This prolongs the service life of the slab nozzle by substantially reducing the erosion rate of the outer wall thereof.
