Abstract
La presente invención se refiere a un método para calentar acero fundido contenido en un cucharón revestido con refractario con la parte superior abierta; caracterizado por introducir una pluralidad de corrientes de gas que contienen oxígeno debajo de la superficie del acero fundido, a una zona de reacción no confinada, espaciada a una distancia substancial del revestimiento refractario; y por introducir una cantidad de combustible no carbonáceo oxidizable en la zona de reacción, suficientemente para que la oxidación del mismo por las corrientes de gas que contienen oxígeno, eleva la temperatura del acero fundido hasta un nivel previamente determinado.
