PROCESS FOR RECOVERY OF IRON/STEEL FROM MILL SCALES AND FINES

摘要

A process for recovering iron/steel from scrap mill scales and fines is disclosed. A process in accordance with embodiments of the present invention comprises mixing mill scales and fines with coke or other carbon containing fines and sealing the mixture in a container. The container is charged into a cupola or blast furnace, where the components react to form molten iron/steel. The recovery process in accordance with an embodiment of the present invention is performed integral to cupola or blast furnace operations and the recovered metal is collected at the base of the furnace as molten iron/steel.

主权项

1. A process for recovering iron from direct-reduced iron (DRI) fines, the process comprising:
mixing mill scale with DRI fines in a container comprising a plurality of vents; exposing the container to heat from a metallurgical furnace, wherein heat from the metallurgical furnace causes the mixture of the mill scale and DRI fines in the container to form a molten metal; and collecting the molten metal at a base of the furnace.
