Abstract

La lance pour injecter un gaz et/ou une poudre au sein d'un métal en fusion, comprend un tube 1 recouvert par un revêtement 2 en matière réfractaire. La matière constituant le revêtement 2 est composée de particules réfractaires et basiques, enrobées dans un liant. Ces particules réfractaires sont frittables à la température du métal en fusion. Utilisation notamment pour injecter un gaz tel que de l'argon dans l'acier en fusion contenu dans une poche de coulée. (CF DESSIN DANS BOPI)The lance for injecting a gas and / or a powder into a molten metal, comprises a tube 1 covered by a coating 2 of refractory material. The material constituting the coating 2 is composed of refractory and basic particles, coated in a binder. These refractory particles are sinterable at the temperature of the molten metal. Use in particular for injecting a gas such as argon into the molten steel contained in a ladle. (CF DRAWING IN BOPI)
