Abstract

Procedimiento para la regulación del contenido calorífico de sustancias de carga sólidas y/o líquidas, como chatarra y arrabio, que se transforman en acero en un crisol por soplado de oxígeno o de un medio de afino rico en oxígeno, caracterizado porque se calienta la carga-aparte del proceso de transformación propiamente dicho, insuflando con una mezcla de aire, aire enriquecido en oxígeno, con aceite finamente dividido, con lo cual se aporta calor a la carga en la cantidad deseada.
