Abstract
El metal fundido en un horno de arco eléctrico es asignado introduciendo un gas en el fundido a través de toberas montadas en el crisol. Cada tobera tiene una parte de entrada que tiene un paso de un diámetro relativamente pequeño. La tobera esta montada en el fondo de un horno de arco eléctrico con parte de entrada que se extiende a través del horno en su blindaje y parte del tramo de ladrillo refractante.
