Abstract
Procedimiento de fabricación de una lanza para el insuflado de un gas en una masa de metal en fusión con vistas al tratamiento de dicho metal, por ejemplo para su desgasificación, que comprende un cuerpo tubular de material refractario y estanco y un elemento poroso previsto para ser unido a una fuente de gas a presión y entregar dicho gas en forma de finas burbujas, caracterizado porque consiste en realizar separadamente, por moldeo a partir del granulado y del aglutinante ya citados, por una parte el cuerpo ya citado provisto del vaciado y de la canalización empotrada en su masa y por otra parte el elemento poroso ya citado, en colocar dicho elemento en el vaciado y someter el conjunto cuerpo-elemento poroso a un tratamiento térmico en un horno a una temperatura de 400 a 500ºC aproximadamente durante alrededor de 8 a 12 horas.
