Abstract:
A nozzle for guiding molten metal flowing from a vessel into a mould, the nozzle comprising a conduit which is elongate along an axis which is oriented substantially vertically during use, the nozzle having at least one upper inlet, at least two lower inclined outlets which are inclined to the axis, and at least one lower axial outlet located generally axially between the inclined outlets, the nozzle further comprising a receptacle located above said at least one lower axial outlet, the receptacle having an upper opening and being defined by sidewalls which are substantially parallel and/or which converge towards the lower extremity of the nozzle, the receptacle receiving a proportion of the molten metal flowing through the nozzle in use prior to such molten metal exiting the nozzle, the minimum combined cross-sectional area of the inclined outlets being at least twice as great as the minimum combined cross-sectional area of the at least one lower axial outlet.
