Abstract

Procédé de production de pièces métalliques moulées finies, ayant une grande qualité de surface et une grande qualité interne. Il consiste à injecter à l'aide de tuyères 5 un mélange gazeux oxygéné contenant 10 à 90 % d'un gaz de dilution dans un bain de fusion, puis à injecter un gaz de barbotage dans le bain, à l'aide des mêmes tuyères. Ces dernières sont constituées de deux tubes concentriques. Domaine d'application : fonderie.
