Abstract

Perfeccionamientos en los procedimientos para la obtención de composiciones para el tratamiento de las escorias metalúrgicas en estado fundido, caracterizados porque están constituidos por unas mezclas de productos carbonatados y productos de carbono libre, los cuales en la actualidad están considerados como unos residuos y desperdicios, de tal forma que por eso se echan el escorial, aptas para modificar las características físicas y/o químicas de las escorias y los residuos metalúrgicos, por medio de su inyección en éstos últimos, en el transcurso de su derrame en estado fundido entre el caldero de colada y el foso de enfriamiento.
