At the blast-furnace process about 30% of oxygen is removed from the burden by direct reduction. Based on Ramm’s principles, the minimization fuel rate model, which is applied at computer-aided support system for blast furnace technology for BF No. 5 at ArcelorMittal Krakow Section, allows effective steering of the direct reduction rate. During the model testing in real condition it’s observed than steering of the direct reduction rate is possible by variation of the oxygen or moisture addition. The present paper introduces an comparative analysis for the data of BF No.5 in Krakow for only-coke and PCI technology work periods. There are also presented results of simulation how the model would appeared if the BF No.5 worked with the ULCOS technology.
