7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

DRIpax™ is an integrated process optimization system for MIDREX DR Plants jointly developed by Primetals Technologies and MIDREX Technologies. This new system was installed for the first time at the MIDREX DR plant Module 2 of Qatar Steel and is now successfully in operation at this plant. The installation at Qatar Steel demonstrates the high prediction accuracy achieved with the new product quality prediction models. Having an accurate prediction – hours before the measured data are available – supports quick decision-making to keep quality targets. As a result, a more consistent DRI quality can be achieved. Due to the improved control of the DRI quality within a tight band limit, significant savings can be expected at the EAFs when the DRI is fed there later on. The DR Plant Expert System, a rule-based advisory system to assist panel operators in decision-making, was developed in a next step to further enhance the system. This expert system will be launched for the first time within the scope of the process optimization system installed at the new MIDREX DR Plant of voestalpine Texas LLC.
