Abstract (en)
Provided is a molten metal discharge nozzle which has a bore configuration capable of creating a low-energy loss and smooth (stabilized) molten metal flow to suppress the occurrence of an adhesion matter. In the molten metal discharge nozzle, a radius r(0) of an upper end (12) of a bore (11) thereof is 1.5 times or more a radius r(L) of a lower end (13) of the bore, and a cross-sectional shape of a bore wall surface 14 taken along an axis of the bore has no bend point. Further, a radius r(z) of the bore at a position downwardly away from the upper end of the bore by a distance z (where L is an axial length of the bore) is in a range between [[L/{(r(0)/r(L)) 1.5 - 1} + L] / [L/((r(0)/r(L)) 1.5 - 1} + z]] 1/1.5 × r(L) and [[L/{(r(0)/r(L)) 6 - 1} + L] / [L/{(r(0)/r(L)) 6 - 1} + z]] 1/6 × r(L).
