ABSTRACT:
An apparatus for introducing gas into a molten metal bath contained within a refractory-lined vessel by the distribution of gas bubbles in the metal bath. The distribution is disbursed and covers a wide areas and mixing within the bath is improved. This is accomplished with the use of a tuyere having a plurality of passageways which cause gas passing through the tuyere to exit into the bath as a series of gas jets which exit from the tuyere at an angle to its longitudinal axis. Preferably, the passageways in the tuyere are spiral so as to produce a swirling or vortical gas motion within the bath.
