TUYERE FOR BLASTING OF MELTS Russian patent published in 2005 - IPC

FIELD: metallurgy.

SUBSTANCE: the invention presents a tuyere for blasting of melts and is dealt with the field of metallurgy, in particular, with a design of tuyeres for blasting of melts by a gaseous agent in metallurgical furnaces of jet-oxidative type. A tuyere for blasting of melts is installed horizontally in a lateral wall of a metallurgical furnace and contains concentrically located pipes with blasting heads forming ducts for feeding of a blasting agent, delivery and withdrawal of cooling water, a circulation chamber located in a base of a tuyere tip. The tuyere has a cistern for water intake installed at an inlet of water in a tuyere and a vacuum pump installed at its outlet. A water tip is placed inside the furnace and has 8-15 through longitudinal holes. Blasting head is located in a lateral wall of a tuyere tip at an angle of α=110-120° to a longitudinal axis of the tuyere. A cockle of a tuyere tip is made dead. The technical result of the invention is a decrease of consumption of water used for cooling, an increase of a tuyere operational reliability and provision of independence of height of a shop structure from a tuyere design.

EFFECT: the invention allows to decrease consumption of water used for cooling, to increase a tuyere operational reliability and provision of independence of a height of a shop structure from a tuyere design.
