This invention has the function of injecting gas and/or gas and powders into liquid metals, using a refractory lance that is endowed with circular movement around its axis, using low values of pressure and sewage, which provides a better distributiom an lower consumption of the powders, resulting in lower cost of the handled metal. The system consists of a refractory lance (7), which is endowed with a roative junction (6), a motor-reducer (5) and a high- pressure hose (8).
La présente invention sert à l~injection de gaz ou de gaz et de poudres dans des métaux liquides, en utilisant une lance réfractaire qui est dotée d~un mouvement circulaire autour de son axe, en utilisant de faibles valeurs de pression et d~eaux usées, ce qui produit une meilleure distribution et une plus faible consommation des poudres et donne un coût inférieur pour le métal manipulé. Le système comprend une lance réfractaire (7), qui est dotée d~une jonction rotative (6), d~un motoréducteur (5) et d~un tuyau à haute pression (8).
