Casting nozzle comprising flow deflectors

Casting nozzle comprising an elongated body defined by an outer wall and comprising a bore defined by a bore wall and extending along a longitudinal axis, X1, from a bore inlet to a downstream bore end, said bore comprising two opposite side ports, each extending transversally to said longitudinal axis, X1, from an opening at the bore wall defining a port inlet adjacent to the downstream bore end, to an opening at the outer wall defining a port outlet which fluidly connects the bore with a casting nozzle exterior,

• wherein, upstream from, and directly above each port inlet, a number of flow deflectors selected from the group consisting of one and two protrudes out of the bore wall and extends from an upstream deflector end remote from the port inlet to a downstream deflector end close to the port inlet, over a deflector height, Hd, measured parallel to the longitudinal axis, X1, and wherein an area of a cross-section normal to the longitudinal axis, X1, of each flow deflector increases continuously over at least 50% of the deflector height, Hd, in the direction extending from the upstream deflector end towards the downstream deflector end.
