Title (EN) COKELESS SINTER BLEND COMPOSITIONS
(FR) COMPOSITIONS DE MÉLANGE DE FRITTAGE SANS COKE
Abstract:
(EN) Examples herein generally relate to sinter blend compositions for use in a sintering process that do not contain coke breeze (0.0% coke breeze), or contain only very small amounts of coke breeze. In particular, these sinter blend compositions are capable of repurposing a mixture of iron-making reverts, having high total and metallic iron levels that re-oxidize so as to become a replacement fuel source for the coke breeze typically used in sinter blend compositions for use in a sintering process, while still managing to produce a sinter with sufficient ISO tumble strengths.
(FR) Des exemples de la présente invention concernent généralement des compositions de mélange de frittage pour utilisation dans un procédé de frittage qui ne contiennent pas de coke broyé (0,0 % de coke broyé), ou ne contiennent que de très faibles quantités de coke. En particulier, ces compositions de mélange de frittage permettent de redéposer un mélange de ferraille récupérée, ayant des taux de fer total et métallique élevés qui se réoxydent de façon à devenir une source de combustible de remplacement pour le coke broyé typiquement utilisé dans des compositions de mélange de frittage pour utilisation dans un procédé de frittage, tout en parvenant encore à produire une fritte ayant des résistances au culbutage ISO suffisantes.
