Abstract
Método de alimentación de toberas en un electrohorno, cuyas toberas comprenden un circuito central de descarga de una sustancia gaseosa comburente y un conducto periférico de descarga de una sustancia gaseosa refrigerante, cuyo método se caracteriza porque prevé el envío al conducto central de una mezcla comburente consistente en oxígeno y gas neutro (N2, Ar, etc.) en porcentajes determinados, y el oxígeno y el gas neutro, para cada una de las toberas, se alimenta a un dispositivo mezclador (13) de alta capacidad de mezcla, pudiéndose regular al menos la presión del gas neutro en la línea de alimentación correspondiente al objeto de modular la presión de la mezcla en función de las características del proceso de fusión.
