Abstract

The invention concerns a plug or brick (1) for injecting gas into molten metal through a molten metal-contacting surface (11) comprising (i) a porous refractory body (2) substantially surrounded by a substantially non-porous body (9) except at the molten metal-contacting surface (11); and (ii) gas conducting means (3, 5) for conveying the gas from a gas source to the porous body (2). The plug or brick is characterized in that the non-porous body (11) is made of refractory material and in that the porous and non-porous bodies (2, 11) have been co-pressed. This plug or brick can be used to inject efficiently and reliably small bubbles into a molten metal bath.
