Abstract

La présente invention concerne un bouchon ou une brique (1) pour l'injection de gaz dans du métal en fusion au travers d'une surface de contact avec le métal en fusion (11), comprenant (i) un corps réfractaire poreux (2) sensiblement entouré d'un corps sensiblement non poreux (9) à l'exception de la surface de contact avec le métal en fusion (11); et (ii) des organes conduisant les gaz (3, 5) servant à amener le gaz d'une source de gaz au corps poreux (2). Le bouchon ou la brique sont caractérisés en ce que le corps non poreux (11) est fait d'un matériau réfractaire, et que les corps poreux et non poreux (2, 11) ont été comprimés ensemble. Ce bouchon ou cette brique conviennent particulièrement pour l'injection puissante et fiable de petites bulles dans le bain de métal en fusion.
