Patent ID: 8905274

Claim:
Pouring nozzle for the continuous casting of steel from a tundish towards a continuous casting mould comprising: at one end, referred to as the upstream end, a generally rectangular-shaped plate with a top surface and a bottom surface, and a tube, the axis of the tube being substantially orthogonal to the top surface of the plate, extending from the bottom surface of the said plate to an opposite end of the nozzle, referred to as the downstream end, the nozzle comprising a pouring channel consisting of an inlet orifice formed through the surface of the plate, a bore in the plate, a bore in the tube, the downstream end of the tube being closed and the pouring channel emerging close to the downstream end through outlets formed in the lateral walls of the tube, the orifice in the plate, the bores in the plate and in the tube and the outlets being in fluid connection, the outlets being disposed symmetrically on either side of the axis of the tube, the centres of the outlets on either side of the axis defining an axis, referred to as the axis of the outlets, substantially orthogonal to the axis of the tube, the axis of the outlets being substantially parallel to a pair of sides of the plate wherein the inlet orifice is oblong and has a major axis and a minor axis, the minor axis of the orifice is parallel to the axis of the outlets, and wherein the pouring channel passes abruptly from an oblong cross section to a circular cross section.
