The HOTLINK® System delivers HDRI to an adjacent EAF at up to 700° C by positioning the MIDREX® Shaft Furnace just outside and above the exterior wall of the meltshop. DRI is discharged hot into a surge bin and then fed directly to the EAF with minimal heat loss.
Low velocity gravity transfer keeps physical degradation of HDRI to a minimum, and there is no re-oxidation of the HDRI due to the sealed design of the HOTLINK® System. The HOTLINK® System is designed with options to produce hot briquetted iron (HBI) or cold DRI (CDRI) without stopping production when the EAF is offline.
The first MIDREX® Direct Reduction Plant featuring the HOTLINK® System for hot charging DRI directly from the reduction furnace into an EAF is part of the Jindal Shadeed steelworks in Sohar, Oman. The 1.5 million metric ton per year plant is designed to transfer and charge HDRI by gravity flow and is equipped to produce HBI or simultaneously or when the HDRI is not required by the meltshop.
