Method and apparatus for preparing agglomerates suitable for use in a blast furnace

摘要

Processes for preparing agglomerates containing iron oxide and suitable for charging as a feed material into a blast furnace and apparatus for effectively carrying out these processes. Waste matter from commercial iron and steel operations containing iron oxide and combustible matter is charged as feed into a rotating cylinder where it is ignited by flame from a jet; then an oxygen containing gas is passed under pressure through a wind box upwardly through passages through the walls of the cylinder and upwardly through particles of burning, tumbling particles of feed matter as this matter moves as a stream and comes into agglomerate form. The treated material is discharged in agglomerate form at the end of the rotating cylinder. These agglomerates may be effectively utilized as iron bearing feed material by charging them along with other charge materials into a blast furnace.
