Abstract

An immersion nozzle (10) for continuous metal casting having an elongated nozzle body (12) formed from a porous, gas permeable refractory material. The nozzle body has a conduit (18) extending longitudinally therethrough and an inner surface (20) which defines the conduit. The nozzle body also includes an outer surface defining a predetermined body profile and channels (24, 26, 28, 30) formed in the outer surface (16) of the nozzle body. A metallic housing (14) encases the nozzle body and has an inner surface (32) dimensioned to substantially conform to the profile of the nozzle body. The housing is secured to the nozzle body by a refractory mortar (40) which forms a rigid relatively air-tight layer between the housing and the nozzle body, wherein the channel means form internal passages in the nozzle. A port (34) is provided on the housing in registry with the channels in the nozzle body. The port is connectable to a source of inert gas, which is operable to force the gas into the passages and into the porous refractory material.
