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. Source

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.

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.

BFI (VDEH-Institute for Applied Research) has developed an innovative thermal tubular regenerator burner system to enhance the heating quality for high-grade charge materials. The system allows a temporary and locally defined release of energy in the furnace. The regenerators preheat the combustion air to more than 1,000°C by heat recovery from flue gases and help to save natural gases by up to 30%. BFI, together with ThyssenKrupp Steel AG, has developed a topometric flatness measurement device and advanced flatness control strategies that offer advantages over conventional techniques and lead to significant improvements in hot rolling processes and strip shape. Control systems are necessary to calculate relations between different process variables, especially their direction and the degree of influence on each other. Through-process quality optimization systems are necessary to significantly improve the efficiency of the mill. Source

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.
