The improved sealing of the conveyor protects the material from environmental influences and the inert system prevents the re-oxidisation of the reactive bulk material and permits the transportation of the DRI without great losses in the level of metallisation.
“In order to produce the same amount of steel a far smaller energy input into the electric arc furnace is required. Therefore the tap-to-tap cycles are reduced and productivity can increase by up to 20 percent”, explains AUMUND Project Manager, Christian Niedzwiedz.
The AUMUND specialised conveyor for HDRI will be used as the connection between the Midrex shaft furnace and an electric furnace arc.
Tosyali is currently building the world’s largest DRI plant, located in Bethioua, Algeria, with Midrex technology. The new direct reduction plant will have a production capacity of 2.5 million tons of DRI and have the option to produce either hot or cold DRI (HDRI or CDRI).
