NOZZLE OF OXYGEN-CONVERTER TUYERE Russian patent published in 2015 - IPC C21C5/48 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to a design of nozzle of an oxygen-converter tuyere. The nozzle includes a lower plate with partitions on its internal non-working water-cooled surface, a dividing plate, an upper plate and nozzles. Each partition adjoins with one of its sides to the outer surface of the nozzle with formation of an angle directed to one side in a circumferential direction at intersection of external and internal surfaces of the partition. Length of the adjacent part of each partition (l_l) is 0.1-0.6 of length of the circumferential direction of the nozzle external surface. Height of partition (h) is 0.1-1.0 of H, where H - distance between the internal surface of the lower plate and the dividing plate surface closest to it along the partition height.

EFFECT: use of invention provides improvement of stability of a nozzle of an oxygen-converter tuyere.
