must be no mix-up, so not one of the metal blocks stored in the smelter hall and the yard is without a nametag. What flows from the casting chute into the furnace is processed into strips, bars, wires, sheets and foils, though this does not happen immediately in Unna. Some materials leave the building as glowing blocks in special transporters – they take with them part of the immense heat energy through which they were created. Further processing is a competition against temperature: in the Duisburg plant the chrome steel blocks are rolled into plates measuring 8 to 9 meters, though that is only a transitory stage. After that, the plates are transported to Ruhrort for sanding and then to the Bochum plant, where they are processed into four-millimeter-thick strips – at a residual temperature that remains at 300 degrees Celsius. A MATERIAL THAT REVOLUTIONIZES THE AUTOMOTIVE WORLD The final product – Aluchrom 7AI YHF – is a new creation that emerged from a federal research product and was awarded the environmental protection prize by the BDI, Germany’s main industrial association. The material, which is amalgamated with such foreign elements as yttrium and hafnium, is used to produce foils with a thickness of 30 to 40 micrometers. These are key components of modern metal catalysts for automotive engines, which have considerable advantages over ceramic, the classical carrier material; thanks to their fast heating, they are al- The materials with the toughest requirements have to go through the fire three times - only then do they reach the highest level of purity. What flows from the casting chute into the furnace is processed into foils, bands, bars, wires and sheets. TK Magazine | 1 | 2004 | Alloys from the finest smelter VIM FURNACE 91 ready fully effective in the start phase. The products concocted in Unna are among the most precious around, and are turned out in significant volumes. In 2002, more than 32,000 tons of nickel basis alloys were supplied, a third each to Germany, Europe and the United States. In the nickel segment, which was launched with coinages in the mid-19th century, ThyssenKrupp VDM is the world market leader. Added to this must be about 5,000 tons of special precious steels per year. Unna even helps ensure a pleasant evening in front of the television, since high-value shadow masks in cathode ray tubes are made of the special alloy Pernifer 36; they resemble a sieve with holes spaced 20 micrometers apart, a magnitude that the human eye basically cannot perceive. The material hardly stretches under high temperatures and thus allows for the creation of sharp color dots on the screen. Pernifer 42, meanwhile, serves as a carrier material for integrated switches, while Conicro 5010 W is a heat-resistant material used in the thrusters of the Ariane rocket. The director of the Unna works, Dr. Jürgen Loh, who holds a doctorate in engineering, is a very competent guide through the amazing maze of high-performance materials, and one who enjoys painting the possibilities of the future. Crofer 22 APU, he points out, is an entirely new iron-chrome alloy characterized by tremendous heat resistance, conductivity and a low stretch coefficient – an ideal material for the serial production of fuel cells, the revolutionary power system expected to revolutionize the automotive world. 7
92 STAINLESS A material for the future Stainless steel has a long and unbroken tradition. Applications can be found in all areas of life By Christa Klein Thanks to its precisely manufactured surface shape, the NIROSTA ® membrane concave mirror makes very effective use of solar energy Stainless steel put to practical use on the dining table, in the form of gleaming cutlery Stainless steel is the ideal material for surgeons, who require clinical purity and sterility for their surgical instruments Agroundbreaking invention became a world-renowned brand – NIROSTA ® , an acronym standing for NIcht ROstender STAhl, the German term for rust-resistant steel. The patent was registered by the Fried. Krupp company as early as 1912 for the manufacture of rust-resistant steel, and its sale under the NIROSTA ® brand started 10 years later, in 1922. Around the same time, Thyssen also started to manufacture rust-resistant steels, and the two companies cooperated in founding the Deutsche Edelstahlwerke AG in 1927. The triumphant march of rust-resistant metallic materials dates back to this time, and has continued without interruption to this day. ThyssenKrupp Stainless is one of the few providers worldwide that can boast a complete range of rust-resistant stainless steel, basic nickel alloys and titanium. Rust-resistant stainless steel, in particular, has developed a special allure and is found in a variety of everyday applications: NIROSTA ® is used for custom-made consumer goods, industrial applications, and in architecture. The surface of this stainless steel is aesthetically pleasing, and found frequently in homes, while the material’s particular advantage in medical applications and in the food and tobacco industry lies in its resistance not only to rust but to heat. The products’ corrosion-resistance is accompanied by the highest possible level of purity and cleanliness. Stainless steel has long become a symbol in itself, a material that mirrors and reflects the modern world in a perfect combination of elegance and practicality. Would the spectacular roof of the Chrysler Building in Manhattan, covered in rust-resistant steel in 1929, have otherwise become so famous? Or remained known around the world for more than seven decades? Stainless steel will continue to fire the imagination of designers and architects as well as material specialists who are steadily working on extending its areas of application. For if this material owns something, it is the future. “Form follows function” – a principle that is also true in the case of the stainless steel chair, which combines both safety and beauty The architect Frank O’Gehry raised a monument to stainless steel at the Neue Zollhof harbor front development in Düsseldorf TK Magazine | 1 | 2004 |
