An apparatus for continuously casting metallic strip material includes a tundish, and a nozzle comprising a curvilinear element, with an orifice passage in the element having substantially uniform cross-sectional dimensions throughout the longitudinal extent thereof. Disposed outside the nozzle is a cooled casting surface movable past the nozzle in a direction substantially perpendicular to the longitudinal axis of the orifice passage. First and second inside surfaces of the element define the orifice passage through which molten metal is fed to the casting surface.

An apparatus for continuously casting metal strip comprising: a tundish for receiving and holding molten metal, a nozzle comprising at least one separate substantially U-shaped curvilinear element disposed in the tundish and opening into the tundish, said curvilinear element having an elongated orifice passage therein defined between a first side portion and a second side portion of the curvilinear element, the orifice passage extending along the length of the U-shaped curvilinear element and approximating the width of the strip to be cast, said orifice passage having substantially uniform cross-sectional dimensions throughout the longitudinal extent thereof, and a cooled casting surface at least as wide as the strip to be cast, disposed at a standoff distance of less than 0.120 inch from the nozzle, movable past a discharge end of the orifice passage in a direction substantially perpendicular to the longitudinal axis of the orifice passage, said first side portion located downstream with respect to the direction of movement of the casting surface and having substantially planar inside surfaces defining the orifice passage, and an outer, lip projecting surface at the discharge end of the orifice passage disposed toward, facing and in complete parallelism with the casting surface for a length of at least 0.01 inch, the outer, lip projecting surface of the first side portion being relieved to define a lip projection at a location beginning at the point of termination of complete parallelism.
