Abstract (en)
[origin: US6849228B2] A blowing lance nozzle (1) having: a central tube (2) supplying stirring gas, an inner tube (5) for intake of a cooling liquid, an outer tube (10) for evacuation of the cooling liquid, a heat exchanging space (13), and an outlet conduit (15) for the stirring gas exiting from each orifice (4) in the front wall (3). The front wall (12) has a central recess (16) which is oriented towards the central orifice (8) and has a recess height/recess base ratio not less than 0.35. The heat exchanging space has a section for allowing passage of the cooling liquid through the space at a speed which is substantially constant, so as to obtain a cooling liquid passage speed, through the space, which is more or less constant.
