Abstract
Una lanza metalurgica para introducir gas desde arriba dentro de un volumen de metal en un contenedor que tiene una cabeza 12. La cabeza 12 tiene por lo menos un expulsor 20 formado en la misma. El expulsor 20 comprende una tobera 24 Laval rodeada por un pasaje 30 de gas de refuerzo. Tanto la tobera 24 Laval como el pasaje 30 de gas de refuerzo se comunican en sus extremos proximos con una camara 22 de suministro de gas comun. El pasaje 30 de gas de refuerzo se comunica con la camara 22 mediante un primer miembro 38 de orificio anular que determina la separacion de porcentaje de flujo del gas a traves de la camara entre la tobera 24 Laval y el pasaje 30 de gas de refuerzo.
