Steel Industry in Germany

With 17.2 billion euros, the steel industry in Germany is responsible for about 30 per cent of the value creation achieved by the European steel industry. About two-thirds of steel in Germany is produced in integrated steel mills (blast furnace, steelworks and rolling mill), the remaining third via the electric steel route.

Slag treatment at Kardemir integrated iron and steel works - [PDF

nte ev g, Mi ounts of solid wastes, which are mainly blast furnace and steel . 74 ( Integrated iron and steel plants generate large amounts of solid wastes (Szekely, 1996).

Application of magnetic separation to steelmaking slags for

In this study, a basic oxygen furnace (BOF) steelwork slag obtained from the Kardemir integrated iron and steel works, Karabuk, Turkey is used. A drum magnetic separator system with pre-engineered crucial processing parameters of drum revolution speed, drum radius, drum flesh thickness, and magnitude of the magnetic field applied is utilized, as these parameters have a competing influence on the results.

Utilization of Basic Oxygen Furnace (BOF) slag in the

The iron oxide-devoid slag, on slow cooling, disintegrated into fine powder. The water-cured cubic specimens of quenched slag products were tested for their compressive strengths. The cementing properties of the quenched slag products were improved by formation of hydraulic phases and showed considerable strength after 28 days of water curing.

Turkish slag cement industry seeks new markets - Article on

Kardemir Joint Stock Co is owned by the workers of Kardemir Steel Works and residents of Karabuk, the town where the steel plant is located. The steel factory is designed to produce 1Mt of steel a year and supplies slag waste to Karçimsa which was opened in the late 1990s and is capable of producing 241,000t of slag cement a year.

Iron and steel industry in the United States - Wikipedia

Integrated steel mills. In , there were 9 operating integrated steel mills in the United States (plus one idled), down from 13 in 2000. Integrated mills produced 31% of the steel produced in the US. In an integrated steel mill, iron ore is reduced to metallic iron.

Water Requirements of the Iron and Steel Industry

and for quenching slag. In operations such as rolling steel in which the water comes into contact with the steel being processed, better quality water is used, although water containing as much as 3,410 ppm dissolved solids has been used for this purpose. Treatment of water for use in the iron and steel industry was not widely practiced.

STUDY OF IRON AND STEEL SLAG AS A PRODUCT WITH RESPECT TO

Mar 04, · Steel mill slag has more weight, higher hardness and density; it is less porous and highly resistant to polishing and wear and as such is very suitable for road building [13]. Slag, the by-product of steel and iron producing processes, has been used in civil engineering for more than 100 years. Rapidly water-cooled Blast Furnace

Sustainable Approaches for LD Slag Waste Management in Steel

May 16, · Reduce, reuse, and recycle are important techniques for waste management. These become significant for improving environmental and economic condition of industries. Integrated steel industries are generating huge amounts of steel slag as waste through the blast furnace and Linz–Donawitz (LD) process. Presently, these wastes are disposed by dumping in an unplanned manner, which causes many
