Abstract
An inner nozzle for casting molten metal from a metallurgical vessel incorporates a substantially tubular portion with an axial through bore, and an inner nozzle plate comprising a bottom flat contact surface and a second surface opposite the bottom contact surface and joining the wall of the tubular portion to the side edges of the plate. The inner nozzle incorporates a metallic casing cladding at least a portion of some or all of the side edges and second surface but not the sliding plane of the inner nozzle plate. The cladding is provided with a metallic bearing surface, facing towards and recessed with respect to the contact surface and extending from the cladded portion of the side edges beyond the perimeter of the contact surface. The bearing surface is defined by the ledges of at least two separate bearing elements distributed around the perimeter of the plate.
