The invention relates to a casting nozzle for a horizontal strip casting system, in particular for casting steel strip, wherein the nozzle is designed as a narrow rectangular hollow block having a bottom, top and two side walls and made of refractory material, the outflow region being located only slightly above a cooled continuous belt receiving the outflowing melt. Viewed in the flow direction, it is provided that the clear cross-section of the hollow block in the outflow region reduces uniformly in the direction toward the outflow and the end face of the bottom of the hollow block is designed with respect to the surface of the continuous belt such that the melt contacts the continuous belt perpendicularly.
A casting nozzle for a horizontal strip casting facility having a cooled continuous belt, said casting nozzle comprising a rectangular hollow block which is defined by a bottom, top, and two side elements and is made from refractory material, said hollow block having an outflow region terminating in an outflow for feeding melt onto a continuous belt, said hollow block defined by a clear cross section which, as viewed in flow direction of the melt decreases in the outflow region uniformly, wherein the bottom of the hollow block has an end face configured to enable melt to contact the continuous belt perpendicularly, wherein the bottom ascends in relation to the top.
