Abstract
The invention relates to metallurgy and concerns multinozzle water-cooled tuyere for melt blowing during oxygen-converter steel production. Tuyere includes concentrically located tubes, which tubes form channels for supplying and removal of the cooling agent (water), channel for gas supplying and the tip with the nozzles. The lower end of the central pipe is made slanting, at that the distance from the inner surface of the tip to the nearest and diametrically opposite points to it the furthermost point of this end is determined from the claimed ratio. The construction provides improved cooling of the central part of the tuyere tip.
