HDRI

Hot DRI is extracted from the DR plant reactor and is directly conveyed to the EAF at high temperature. This solution allows recovering the thermal energy of the DRI, which is leaving the reactor at temperatures of approx. 700°C. For every 100°C increase in DRI temperature, approx. 26 kWh/tLS are saved at the EAF and 5% decrease in tap-to-tap time is achieved.
