Presentation outline • Background - steel industry trends • Critical issues for the global steel industry – Future structure of China’s steel industry – Consolidation – Future Blast furnace trends • Implications for coke • Recent studies to understand coke its reactions & performance • Summary and Conclusions Key theme

The world has changed

But the need for coke and hard coking remains Areas where the world has changed……. • Industry structure – consolidation; the new wave • Regional consolidation moves global • Price volatility – industry consensus; potential to be lower • Increased market “power” re customers (flat products) • Current high profitability in the steel industry continues • Raw materials – too early to be definite, but potential move to higher quality seaborne raw materials Areas where the world has not changed • New phase of strong demand growth - BRICS • China driving major uplifts • Technology trends - BF still king • Planned new capacity SE Asia, Brazil, India etc • Drive for higher productivity = high quality RM’s esp coke • Environmental conditions • Raw materials – the benefits of high quality esp coke BackgroundBackground The global steel industry continues to power on Mt 1200 New golden Fall of Berlin Wall age?

1975 – 1980 2.2 Steady global recovery from oil shock

1980 – 1985 0.1 Second oil shock, recession, reduction in steel intensity 1985 – 1990 1.4 Strong steel efficiency drive

1990 – 1995 -0.5 Fall of Berlin wall, collapse of USSR, continued steel efficiency gains 1995 – 2000 2.4 Slow CIS recovery, signs of emerging China

Source: NDRC FutureFuture structurestructure ofof China’sChina’s steelsteel industryindustry Plans and Implications • Industry structure optimization policy – Steel mills, especially big ones, are supported to grow through M&A • Industry layout improvement policy – Steel mills encouraged to relocate or build greenfield plant in coastal or along Yangtze River areas to take advantage of markets and overseas raw materials – Inland steel mills should cap the capacity based on the available ores in line with the local markets and the mineral resources – Those steel mills locate in provincial capital and tourism cities are not allowed to expand capacity of iron-making & steel-making • Raw materials policy – International cooperation with the overseas mineral resources should be enhanced

• Worldwide move to privatisation • Ending “Social/national” business • Shareholder demand for value creation • Capital & opex constraints • Government support/interference • Withdrawing of Bank supports • Shareholder value destruction • M&A/Alliances, regional consolidation • Inability to retain cost reductions Financial • Inability to raise capital Performance

• SOx, NOx, Dioxins • Emerging regions • CO2 building own capacity • Effluent discharge Environmental Consolidated Fragmentation • Technology diffusion • Hazardous chemicals & Overcapacity • Capacity creep • Waste management Concerns Steel • Low entry/high exit • Poor public perception Industry barriers • Economies of scale

Global / Cross-regional consolidation: • Mergers between groups (competition issues?): catalyst for rapid consolidation • Russian mills going global • Acquisitions in Latin America, Middle East, Ukraine (partly driven by captive raw materials)

Product consolidation: • Focus on flat products • Limited in long products: Ample opportunity but disincentives SteelSteel industryindustry consolidationconsolidation Regional consolidation: CIS, China and Brazil; Europe and N. America

Strong Regional Consolidation CIS: Regional Second Tier Firm Consolidation consolidation between CIS countries EU, Eastern US / Canada Europe Japan: consolidate to two companies

? China: government supports consolidation, but not foreign majority stakes Brazil

Regional consolidation: likely to result in more benefits than global consolidation: • Operations are strongly linked (both customer and supply side) to regional markets • Most products sourced regionally with some global support, even though ~20% of steel production is aimed at global customers Source: Company reports and news coverage; World Steel Dynamics SteelSteel industryindustry consolidationconsolidation Fragmented industry now consolidating – regional impact Total Crude Steel Production 20 750Mt 799Mt 777Mt 788Mt 847Mt 850Mt 902Mt 934Mt 1069Mt 1129Mt

ULCOS (Ultra Low CO2 Steelmaking) program likely impact after 2025 • Step 1 (2005–10) exploring wide range of steelmaking concepts

• Including future BF concepts

–O2 blast – Biomass/plastics injection

– Top gas recycling with CO2 removal

–CO2 sequestration FutureFuture BFBF trendstrends Blast Furnace - future evolution Top Gas • Outlook for the BF Recycling – Decline in no = higher productivity Scrap/Metallic DRI Pre-Heated – Expanded campaign life >20 years Burden – Shorter down periods Mid-Furnace – Higher PCI, O2, lower fuel rates Fine IO Injection (Oxy) – More stable operations – Enhanced computer models and control, value-in-use Plastics – Enlargement during relines – New hearth designs New hearth for high liquids drainage Summary future BF trends and implications • BF will remain the main source of iron for steelmaking • Longer lived, high productivity & efficiency future for the BF • Size will increase as MBF’s move to larger >3000m3

Overall implications likely to see more productive, efficient BF operations requiring high quality coke likely to be made with increasing quantities of higher quality hard coking coals What happens if you use poor quality………… Blast Furnaces must be looked after! Overall implications for coke in the new world • Current trends:- – China’s future, growth and structure – Industry consolidation – Future BF trends

• All lead to the conclusion that – Coke will remain vitally important to steelmaking – Coke quality trends are likely to be for higher quality – Coke ovens are a valuable asset – Implications are for continue requirements for HQHCC RecentRecent studiesstudies ofof cokecoke itsits reactionsreactions && performanceperformance Understanding coke reactions and performance • Are traditional methods for assessing coke still relevant • BF operations have changed and will continue • Coke characterisation tests developed 20 years ago!! – Cold strength probably OK – Hot strength(CSR) generally useful

CRI/CSR indices similar, but there is less differentiation between cokes under the blast furnace profile. CSR and CRI overestimate the differences in cokes 2. Strength indices show different behaviour between CSR and BF profile. The drop at high rank is likely due to thermal damage (as shown in nitrogen data) 3. High rank coals increase fines when 100% of battery feed, but do not appear generate increased fines when present in blends.

Key Findings 1. Coke behaviour depends on where you are in the BF. 2. At the centre, thermal effects predominate.

3. At the walls (and most likely the mid radial locations, chemical attack via CO2 becomes much more significant). 4. Similar, non-additive behaviour MV/LV blend.

Coke microstructures showed significant difference between the effects of • CSR conditions & • a typical BF gas-temperature profile

• CSR reaction penetrated deep into the coke lump for all cokes studied • BF profile resulted in reaction confined to lump surface.

Coke made from higher rank coals showed a more limited change in coke microstructure. RecentRecent studiesstudies ofof cokecoke itsits reactionsreactions && performanceperformance US LV v Aust LV Coals – Effect on coke strength
