It is designed to convert iron pellet/lump ore into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. O2 is removed from the iron ore by chemical reactions based on H2 and CO, for the production of highly metallized DRI. The schematic process flow of the direct reduction process is shown in Fig 1.
In the melter-gasifier non coking coal is gasified by injecting oxygen and pre-reduced iron ore/ pellets are melted. The outgoing gas is used for reduction of iron ore/pellets in the upstream shaft furnace. The schematic process flow sheet is shown in Fig 1 and the schematic view of main Corex plant sections is shown in Fig 2.
What Is Iron Ore Pelletization Process. The process of pelletization begins with the use of finely powdered grains of iron ore. These grains are then converted into balls.
