Abstract
Official abstract text for this publication.
An exemplary embodiment relates to a submerged entry nozzle (SEN) for use in metallurgy, in particular for transporting a metal melt from a first metallurgical unit to a second metallurgical unit, for example during slab production in continuous casting of ferrous and non-ferrous melts. The SEN is called nozzle hereinafter.
First claim
Opening claim text (preview).
The invention claimed is: 1. Submerged entry nozzle comprising a substantially tubular body with a central longitudinal axis (LA) and a passageway ( 16 ) extending from an inlet port ( 12 ) at a first end of the nozzle, which is the upper end of the nozzle in its use position, toward a second end of the nozzle, which is the lower end of the nozzle in its use position, wherein the second end of the nozzle provides a bottom ( 22 b ) which is either flat or convex, when seen from the outside, wherein said passageway ( 16 ) merges into at least one outlet port ( 18 ), which is designed as a long slit, wherein the slit has long side walls ( 18 w ) extending in a plane arranged at an angle of <45 degrees to a plane comprising the central longitudinal axis (LA), wherein the slit has a spiral or helix-like extension and continuously extends from a position at a distance to the bottom ( 22 b ) into the said bottom ( 22 b ), to allow a metal melt to flow out of the nozzle in a horizontal and in a vertical direction. 2. Submerged entry nozzle according to claim 1 , wherein the slit has a linear extension. 3. Submerged entry nozzle according to claim 1 , wherein 5-30% of the length of the slit extend within the bottom ( 22 b ) of the nozzle. 4. Submerged entry nozzle according to claim 1 , wherein the slit has a length, which is more than 3 times its width. 5. Submerged entry nozzle according to claim 1 , with several slits, arranged at equal angles to each other along the outer periphery of the nozzle.
