The current invention contemplates recycling steel making materials back into the process. The various embodiments of the current invention include methods of preparing and manufacturing steel processing materials comprising at least partially recycled steel making materials. In one embodiment, the steel processing material comprises a dried post combustion material(PCM), the recycled steel making material, and a slag foaming material. In various embodiments of the current invention, the recycled steel making material may have moisture content removed and/or may be mixed with other processing materials.
L'invention porte sur le recyclage de matériaux de fabrication d'acier réintroduits dans le processus. Différents modes de réalisation selon l'invention concernent des procédés de préparation et de fabrication de matériaux de traitement d'acier contenant au moins en partie des matériaux de fabrication d'acier recyclés. Dans un mode de réalisation, le matériau de traitement d'acier comporte un matériau de postcombustion séché (PCM), le matériau de fabrication d'acier recyclé, et un matériau expansible de laitier. Dans différents modes de réalisation selon l'invention, le matériau de fabrication d'acier recyclé peut contenir des matières humides ôtées et/ou peut être fixé à d'autres matériaux de traitement.
