Abstract
The proven VAiron sinter-process automation system has been enhanced with innovations developed as a result of close collaboration between voestalpine and Siemens VAI. A sophisticated tracking system for bulk materials throughout the ironmaking plant, from ore preparation to the blast furnace, provides the basis for an advanced process optimisation system. Material control in the blending yard and sinter plant has been integrated into a common control model. Diagnosis and control functions have been bundled into a sinter expert system. The chemical properties are stabilised by automatic adaption of the raw material mix. An enhanced burn-through point control system that considers physical and chemical properties has been developed. The waste gas control minimises environmental impact through reduction of SO2 emissions.
