ABSTRACT:
An annular tuyere is provided having improved corrosion resistance, particularly at low gas flow rates and useful in the production of metal alloys. The tuyere may have a solid core defining an annulus between the core and an outer tubing. A method is also provided for raising the critical bath temperature at which the tuyere would melt and to minimize the gas flow necessary to cool the tuyere tip.
