ABSTRACT:
Nozzle means are disclosed that are particularly suited for use in combination with tuyeres of metallurgical reducing or refining vessels. The nozzle means is axially positionable within the tuyere to maintain a supersonic jet as the tuyere is consumed. Both axially divergent-convergent and convergent-divergent nozzle means are disclosed. Also disclosed is a combination of nozzle means to effect rapid shut-off of the tuyere by positioning a conforming convergent first portion into the convergent second portion of the nozzle means.
