ABSTRACT:
An immersed metallurgical pouring nozzle, such as a submerged entry nozzle for pouring molten steel, comprises a body of refractory material, such as graphite alumina, which defines a flow passage. An annular member of refractory material, such as zirconia with a very low or no-content of carbon, whose erosion resistance is higher than that of the body of the nozzle is wholly encapsulated in the material of the body of the nozzle.
