Abstract

1. A permeable device for introducing gas into a bath of liquid metal, comprising a case (1) in which is disposed an enclosure (3) which is open in its upper part, in which is placed at least one permeable refractory element (8) retained by a first refractory binder (10), the bottom (5) of the enclosure (3) having an orifice (6) connected to an inlet tube (2) for said gases, and the enclosure being fixed in the case by a second refractory binder (11), characterised in that the case is in the form of a box open in its upper part and having a bottom through which the gas inlet tube (2) extends in a sealed manner.
