Abstract
The subject of the invention is a nozzle (1) for introducing a liquid metal into a mold for the continuous casting of metals, of the type comprising a tubular first part (2), one end of which is intended to be connected to a vessel containing said liquid metal and the other end of which emerges in a hollow second part (4) of elongate shape, at least one portion of the internal space (3) of which is oriented approximately perpendicular to said tubular first part (2), said hollow part (4) having an outlet (5, 6) at each of its ends, as well as one or more outlet orifices (7-17) provided in its bottom (18) and/or its lateral walls, a bar provided with holes (22, 22', 23-34) being placed in the internal space (3) of said hollow part (4) so that the liquid metal necessarily passes via said holes (22, 22', 23-34) before passing through said outlet orifices (7-17), wherein said bar (19, 38, 39, 41, 43) includes, on at least one portion of the width of its upper face, a raised part (20, 37, 42, 44) whose top lies along the longitudinal horizontal axis of said hollow part (4), said holes (22, 22', 23-34) being distributed on each side of said top.
