| Zusammenfassung: | A nozzle which is submerged in molten metal during steel casting comprises a nozzle body, a nozzle passage provided through the nozzle body such that a molten-metal-and-gas stream can be introduced into the nozzle body at a predetermined point, and at least one discharge port, wherein the discharge port is bordered by a projecting part that presents a surface that is inclined toward the introduction point for the metal/gas stream at a slanting angle, relative to the longitudinal axis of the nozzle body, that is greater than 0 DEG . The nozzle has a substantially prolonged service life. |
