Abstract

FIELD: metallurgy. SUBSTANCE: water-cooled blower nozzle providing hot blow into blast furnace has protective material layer to resist liquid cast iron attack. The layer consists of zirconium or alumina members in the form of parallelepipeds and stops which fix the distance between them and reinforcing steel filling fastened to outer nozzle shell with fingers. EFFECT: improved structure.
