FIELD: metallurgy.
SUBSTANCE: tuyere is horizontally installed in jet-type instrument, contains concentric located pipes, forming routes for oxygen feeding, supply and cooling water drainage, connected by point, in side wall of which there is located blasting nozzle on-the-mitre 110-120° to longitudinal axis of tuyere. Tuyere is additionally outfitted by facility for its fixed angle swivel around main axis. For feeding of liquid fuel tuyere is outfitted additionally by internal pipe and connected to it fuel nozzle, located in point and joined to blasting nozzle.
EFFECT: increasing of metal extraction and furnace productivity.
