Abstract

A blowing lance for treating molten metal in a ladle has a tip fitted with a porous plug which is immersed in the melt. The plug is long in the direction of the longitudinal axis of the lance and comprises a porous refractory core surrounded by a coaxial refractory non-porous sleeve. One end of the plug is connected to the pipe through which gas is supplied to the core, and the other end is the only exit, of strictly limited surface, for gases required to pass through the melt. The plug increases the time of passage of the gas through the melt.
