TIP FOR OXYGEN LANCE Russian patent published in 2004 - IPC

FIELD: metallurgy.

SUBSTANCE: proposed tip has head and flange connected by means of nozzles. It is all-cast; peripheral nozzles are interconnected by means of additional flange over outer surface; said flange is used for separating the cooling liquid inlet from outlet. Longitudinal fins made in direction towards center of tip are connected with central nozzle or with central solid rod, thus dividing the central part of tip into sectors. Outer surface of head and edges of nozzles adjoining it are provide with heat-insulating coats in form of separate sections divided by passages. Inner non-working water-cooled surface of tip head may be provided with radial fins-projections whose height is compatible with thickness of head walls.

EFFECT: increased utilization factor of material; low cost.
