Abstract

1362701 Continuous casting MANNESMANN AG 21 July 1971 [31 July 1970] 34292/71 Heading B3F A device 3, 5 through which molten metal is passed, e.g. from a tundish or teeming ladle, to beneath the powder-covered surface of a metal bath in a mould containing a cooled mandrel 10, has a hollow body 3 arranged vertically and at its end beneath the surface has a part-ring outlet duct 5 which extends horizontally or at an angle (up to 45 degrees) to the horizontal, upwardly or downwardly, and the outlet apertures 6 of which are at an angle α to each other; the vertex of the angle α, in the plane containing the axis of the duct is, as indicated, substantially on the one of the two arcuate lines (shown broken), where the inside surface of the duct intersects the plane, which has the smaller radius of curvature. It lies between 45 and 180 degrees. The ring of which the duct 5 is nominally a part may be polygonal. The cross-section of the passage through the body 3 (which may be rectangular in section) and the total of the cross-sections of the outlet apertures 6 are both several, e.g. three times, greater than that of the outlet from the tundish or ladle.
