8 Pellet Supply Major Changes Changed from acid to fluxed pellets in late 1970s. Changes throughout 1980s and early 1990s aimed to improve pellet properties and reduce variability. Observed greatly improved blast furnace production and efficiency. Pellet supply quality has slowly declined since mid 1990s, mostly due to cost pressures and ore reserves. In 2007 changed from hematite ore to magnetite concentrate for pellet production. 8

12 Descending Probe Descending probe measures temperature across the furnace radius. Can be correlated with RUL test results. 12
13 Project Magnet Converted pellet plant to use magnetite concentrate to enable sale of hematite reserves. Magnetite ore chemistry is very different to hematite ore in terms of gangue elements. OneSteel test work simulated effects of magnetite based pellets on blast furnace operation. Confirmed by companies including Kobe, CSIRO, COREM and Corus. E.g. Pot grate tests for induration extent during pre-heating. 13
14 Magnetite Concentrate Test Pellets Hematite Microstructure of low basicity pellet after preheating showing full oxidation to hematite. (Firth et al, 2004) 14
15 Magnetite Concentrate Test Pellets Hematite Magnetite High basicity pellet after preheating showing distinct core of unoxidised magnetite. (Firth et al, 2004) 15
16 Lump Ore Major Changes Significant effort in 1980s to improve quality and consistency of the lump ore. During mid 1990s cost pressures and dwindling ore reserves saw a winding back of the improvements, with deleterious effects at the blast furnace. Ore Beneficiation Plant (OBP) installed in
17 Ore Beneficiation Plant Ore Beneficiation Plant (OBP) uses jigs, vibrating screens and spirals. Installed to produce lump for the blast furnace from high grade ore dumps. Any magnetite reports to the product. Magnetite ore is bad news in a blast furnace. OBP process greatly affected by geology and physical condition of the ore. 17

21 Blast Furnace Operations Third campaign (Jan 1981 Jun 2004) produced world class results. Raw material quality and consistency was a major factor. Used highly fluxed pellets. High alumina loading. Continuous improvement in fuel rate. Fourth campaign brought challenges with raw material supply and resulting operational issues. 21

34 Conclusion Since 1941, ferrous materials for Ironmaking in Whyalla have been sourced exclusively from the nearby Middleback Ranges. Key objective is to maintain high blast furnace process availability, efficiency and stability at lowest cost, by exercising innovative process design and control methodologies. There is the ever present challenge of diminishing absolute quality and increased variability in raw material inputs for the blast furnace. Rigorous benchmarking is practiced. The fundamental raw material attribute sought is consistency. 34
