TUYERE FOR BOTTOM METAL BLOWING IN LADLE Russian patent published in 2012 - IPC C21C5/48

Abstract RU 2443784 C1

FIELD: metallurgy.

SUBSTANCE: tuyere includes blowdown plug with through longitudinal slot channels, sleeve, stationary tube and removable gas supply tube. Tuyere is equipped with three in-series connected emitters of acoustic vibrations: external one in relation to blowdown plug, intermediate one built into removable gas supply tube, and internal one located in blowdown plug. External and internal emitters are equipped with gas nozzles and cylindrical resonators. Intermediate emitter is made in the form of a cylinder with two round holes in its edges.

EFFECT: use of invention allows improving metal degassing and removing non-metallic inclusions.
