A manifold assembly for a pocket block that is used to introduce gas into a mass of molten metal in a vessel having a refractory lining. The pocket block is formed of a cast refractory material, the manifold assembly comprising a support sleeve having an apertured partition secured within. A gas supply fitting extending from the sleeve and a filament positioning and mounting fitting adjacent the gas supply fitting. A synthetic resin filament net held between the filament positioning and mounting fitting and said apertured partition with the synthetic resin filament net extending upwardly and embedded within the cast refractory material of the pocket block.
Cette invention concerne un collecteur pour un bec d'injection de gaz dans une masse de métal fondu dans une cuve à garnissage réfractaire. Le bec est formé de blocs moulés de matériau réfractaire, et le collecteur comprend un manchon support à l'intérieur duquel se trouve une cloison ajourée, un raccord d'alimentation en gaz partant du manchon et une ferrure de montage et de positionnement de filaments à proximité du raccord d'alimentation en gaz, un filet en résine synthétique maintenu entre la ferrure et la cloison ajourée susmentionnées, ledit filet se prolongeant vers le haut et étant noyé dans les blocs moulés réfractaires composant le bec d'injection.
