Abstract
An improved refractory nozzle for use with a tundish in the atomization of molten metal to produce metal particles for powder metallurgy applications. The nozzle is constructed from refractory material and has a metal sleeve surrounding the nozzle bore near the discharge end thereof but offset a distance from the bore. The metal sleeve minimizes cracking caused by the thermal gradient resulting from molten metal passing through the nozzle to heat the nozzle interior to a temperature higher than the nozzle exterior at the tip.
