The integrated steel works in EU 27 operate most modern plants for the production of a wide variety of high-grade steel products. The blast furnace/converter route will remain dominant within the EU 27 on a long term with a share of 60 %. The basic pre-product for this route is hot metal from blast furnaces. Blast furnaces cannot be operated without coke and they are dependent on high grade coke supply. With a total reductant rate of 499 kg/t HM under the given raw material situation the European blast furnaces (EU 15) are operating near the theoretical minimum. In the R&D EU 27 is amongst others focused on the reduction of CO2 emissions by the development of the oxygen blast furnace process and the Hisarna smelting reduction process. The German steel industry has reduced the specific CO2 emissions related to the sum of hot rolled steel, seamless tubes and forging products by 20 %. The CO2 trading system in EU 27 for the period after 2013 sets new challenges for the steel industry. The benchmarking values set by the European Commission cannot be reached by the plants.

In the years from 2001 to 2007, the world's steel industry experienced a previously unknown boom in steel production and use. This resulted in raw material supply shortages and steep increases in raw material prices, especially in the last four years. Analysts expected this growth to continue in 2008 and 2009. However, in the fourth quarter of 2008, the industry suffered the full impact of the crisis in the financial markets. Demand for steel collapsed. Steelmakers found themselves forced to adjust production, either by stopping individual facilities or by sharply cutting back productivity. Companies and plant operators faced new challenges. Especially the integrated mills - comprising cokemaking, sintering, blast furnace and converter operations - with their typically high capacity are less flexible in terms of cost and operating efficiency under such conditions than mini mills based on electric arc furnaces.

The Steelmaking Committee is organizing scientific and technical cooperation of member steel works from Austria, Finland, Germany, Luxembourg, the Netherlands and Switzerland. The steelmaking committee and the associated subcommittees have identified current trends and developments in steelmaking processes from a European point of view. About 60% of the crude steel in Europe is currently produced by the oxygen steelmaking process and 40% by the electric steelmaking process. The product range is of decisive importance for the layout of the steel-works and the equipment for secondary metallurgical treatment. Regarding steel- making worldwide, thin slabs are increasingly being produced in addition to conventional formats such as slabs, blooms, billets and beam blanks. steel production. The main development trends these days are aiming towards improving energy and resource efficiency, increasing competitiveness, as well as improving efficiency, flexibility, quality and works logistics.

Steel is the material No. 1 of a modern industrial society. World crude steel production in 2012 has reached over 1.5 billion t, the highest ever level. The steel production in Germany and Western Europe show a very high degree of resource efficiency. The steel industry is investing in Europe in the development of new methods with lower CO2 emissions. The requirement of the European Commission to decrease absolute CO2 emissions by in total over 80 % in 2050 compared to 1990 cannot be fulfilled. Innovative steels prevent six times more CO2 emissions in the utilization phase than are emitted in the production of these steel grades. A multi-recycling approach of steel gives a real figure of the greenhouse gas intensity of steel for the primary and secondary production route.

Blast furnaces operated in Europe are highly performed, low in reductant rates and high efficient. Campaign lives of over 20 years have been achieved. Investments have been done in the modernization of blast furnace plants, in new coal injection facilities and new top gas recovery turbines. The lowest limit of reductant consumption under the given boundary conditions and also the resulting CO2emissions has been achieved. AISTech 2015 Proceedings © 2015 by AIST.

About 60 % of the crude steel made in Europe is currently being produced with the oxygen steelmaking process, 40 % with the electric steelmaking process. But of course the product range is of decisive importance for the layout of the steelworks and the equipment for secondary metallurgical treatment. Regarding cast steel worldwide, thin slabs are increasingly being produced in addition to conventional formats such as slabs, blooms, billets and beam blanks. In order to ensure long-term economic success, however, companies must continuously further develop the technologies for steel production. Challenges for the future remain the production of high-purity steel grades as well as the development of zero-error strategies with maximum productivity and flexibility. This report summarizes current development trends.

Numerous plant and process developments have led to the reduced consumption of raw materials and energy, increased yields and improved environmental protection in iron- and steel-producing plants. However, the extreme rise in demand for raw materials and changes in the deposits have created new challenges for plant operators regarding the flexibility and quality of raw materials. Both processes are followed by further process steps in order to manufacture the desired steel grades. Two- thirds of the steel produced in Germany is made via the blast furnace/converter route, and the remaining one-third is made via EAFs. Both routes for steel production are energy-intensive. Steel scrap is used in 42% of Germany's steel production. This demonstrates the sustainability of steel production shown, in particular, by the closed circulatory system of scrap steel recycling.

There are principally four routes for steelmaking. Three are based on iron ore reduction via blast furnace, smelting reduction and direct reduction; one is based on melting steel scrap via the electric arc furnace. Blast furnaces and smelting reduction plants produce liquid hot metal and separate the main amount of the charge materials gangue components via a slag. Direct reduction plants reduce iron ores in the solid state to sponge iron (DRI, HBI) whilst the gangue components remain in the product. The report describes the process developments and current status of iron ore reduction routes as well as some future ideas.

The global steel market has witnessed significant recovery in the year 2010 after an economic downturn across the world. Crude steel production has increased by 15% and rose to a high level of 1.412 billion t. International Monetary Fund reports that global gross domestic product will rise by 4.4% in 2011 and 4.5% in 2012. The World Steel Association expects significant growth of almost 6% for the year 2011 and 2012. The global apparent consumption of rolled steel in the year 2012 is expected to be 160 million t higher than in 2010. The crude steel production in Germany may expand by about 4% in 2011 and, at 45.5 million t, regain its long-term growth trend. The price for ore has risen by 150%, while coking coal has increased by about 75% in the year 2011. The contract prices have risen significantly as a result of the flooding in Queensland, in particular, which results in further burdens for the steel industry.

Iron ore quality has changed. Lower Fe and higher impurities are forcing blast furnaces to higher slag rates and new operational strategies. On top, iron ores are finer, impacting sinter plant productivity and economics for more pellets in the burden. This quality degradation does not seem to be a temporary phenomenon. Also, steel users are demanding cleaner steels to improve properties, reduce weight and compete with other materials. This is a true challenge, deal with challenging raw materials to produce clean steels at very effective cost. This paper shows the evolution of raw materials and implications in Europe, discussing how the players are reacting and the most acceptable trends.
