‘End of waste’ in sight

International Environment Council: BIR Autumn Round-Table Sessions

The recycling industry must remain united as it nears its long- held goal of extricating its end-products, i.e. materials ready for melting or re-pulping, from waste legislation, delegates to the BIR’s International Environment Council (IEC) meeting in Amsterdam were urged by its Chairman, Olivier François of Galloometal in Belgium. Currently under discussion, criteria for establishing the “end of waste” will bring welcome harmonisation and legal certain- ty for the entire EU recycling industry, while at the same time reducing its administrative burden, Mr François explained. ® It is “very important”, therefore, for recyclers to support the final push towards defining the “end of waste” for the various recyclables, he said. “We really must keep this target in mind. We need to be strong and we need to be strong together.” Further developments on end-of-waste criteria for iron scrap and aluminium scrap are anticipated before the end of this join the best year, he added. Earlier, BIR’s Environmental & Technical Director Ross Bar- tley confirmed that the OECD is advancing with its work on Sustainable Materials Management (SMM), with case studies 12. – 16.

Henkel was predestined for an improvement of the process, as the company has a history of innovative developments for metal pretreatment, which have brought about significant improvements relative to conventional methods. In 1995, for example, chromating was replaced by a new kind of pretreatment method, as was iron phosphating in 2002. In both cases, environmental impacts were drastically reduced and industrial processes were considerably simplified. “In terms of the quality of the coating, zinc phosphating process is the optimum,” says Henkel project leader Dr. Torsten Körner. “The challenge we faced was to develop an alternative conversion coating, which would be just as effective and would photos: Henkel offer concrete process benefits.” The The quality of the protection and paintwork are unsurpassed. By introducing the new result of Henkel‘s development work TecTalis pretreatment process, Kögel has raised the bar in the European commercial is the completely new TecTalis pro- vehicles sector.

n 2000, Kögel was one of the first trailer manufacturers to introduce cathodic dip coating with prior zinc phosphat- ingI for frames, axles and other steel components. Today the sector views the quality of the corrosion resistance and coating of the Kögel trailers as the benchmark. „Rust is a thing of the past on semi-trailers, but our responsibil- ity goes further than rust prevention. As a manufacturer on an expansion course throughout Europe, not only the quality of the products but also the sustainability of the production processes is crucial.“ states plant manager Franz Tropsch. Zinc phosphating has been the standard surface pretreatment method Up to three metric tons of steel are processed for the frame of a semi-trailer.

Dr. Schönherr: “This precision ultimately paid off, because the TecTalis process performed perfectly at Kögel from the very beginning.” Kögel head of production Tropsch was also satis- fied: “In terms of corrosion protection and paint adhesion, TecTalis meets the high standards to which we had become accustomed from the zinc phosphating process.

METALL | 64. Jahrgang | 1-2/2010 17 Highest building of the world opens German companies supplied stainless steel for the façade of the Burj Tower in Dubai

The Burj Tower in Dubai ofﬁ cially opened Janu- ary 4h and is now accessible for the public. At 818 meter height, the tower is the highest building of the world. The skyscraper’s façade is covered with stainless steel made in Germany. The company ThyssenKrupp Nirosta produced the material in Krefeld and rolled it in its plant in Dillenburg.

ts German partner, Strukturmetall (near Heilbronn) processed the material and supplied 400 tons to Dubai, where it was cut to slices. TheseI strips, 420 millimeter in width, are wall-mounted at the front sides of the floor platforms and include the huge glass windows of the outside front. Since 2004, the gigantic tower was built up. 850 posts, driven up to 55 meters deep into the desert floor, now carry a load of 230,000 cubic meters of concrete and 31,000 tons of steel. In selecting the material to frame the window front the engineers and designers were guided not only by stainless steel’s architectural beauty and resistance to environmental influences. They also took care to ensure that the material would not reflect the sun too strongly and distract pilots approaching Dubai Airport. “Guaranteeing consistently high surface quality for this huge facade was a particular challenge,” says Gert Weiss, product service manager with ThyssenKrupp Nirosta. Helmut Baumgartl, managing director of Struk- turmetall, adds: “The requirements set by the developer Emaar in Dubai were very high. That’s why the client insisted on material and know-how from Germany.” The task of Strukturmetall was to emboss a pattern (5WL) into the smooth stainless steel panels to increase rigidity and reduce weight. “This ensures a higher stiff- ness and a specific reduction of weight”,

Light and compact - Gearbox housing for the new ZF 8-speed automatic transmission

The new 8 speed automatic transmission from ZF makes vehicles more economical. Honsel assisted ZF by developing the optimal casting process for the gearbox housing. The company supplies light compact housings as well as high-precision control parts for the gear shifting mechanism. The high functional density of the transmission system, whose size is virtually equal to that of the 6-speed automatic, means that the individual components have to fulfil more functions. This causes high demands on the development of the housing. Hon- sel tested and improved the castability of the housing, the valve body and the ditch plate, which together form the Photo: Honsel control unit. The result is a compact Gearbox housings for the new ZF 8-speed automatic transmission lightweight gearbox housing weigh- ing only 13 kg, which is virtually the in Nuremberg.

The effect of two-step austempering processes on the microstructure and mechanical properties of austempered ductile iron has been investigated. Two ductile irons where used; the ﬁ rst is unalloyed ductile iron while the second one is alloyed ductile iron with 0.26% Cr. All the specimens were initially austenized at 900 °C for 1 h, then quenched in salt bath at temperature of 290, 330 and 370 °C respectively for 5 minutes. Then the temperature of the furnace is raised within a rate of 29 °C/hour for a period of 1 hour. Thereby, the furnace temperatures will reach to 319, 359, and 399 °C, respectively. Finally the samples were cooled using forced air to room temperature. The effect of this two steep austempering heat treatment on the microstructure of the materials and mechanical properties were examined. The results reveal that the tensile strength and hardness decreases with increasing the austempering tempera- Fig. 1: Schematic drawing of the austempe- ture.

ADI microstructure

The microstructure of the two-step ADI is illustrated in figs. 3 a, b and c. It is noticed that the effect of lower austempering temperature of 319 °C obtained lower bainite and mixed bainite at 359 °C while at 399 °C upper bainite is formed. X-ray diffraction analysis (a) austempered at 290/319 °C (a) unalloyed DI The X-ray diffraction pattern of the investigated alloys was used to estimate volume fraction of retained austenite and its carbon content. Tables 3 and 4 give the estimated values of both the volume fraction of retained austenite and its carbon content for each austempering process. It is clear that the volume fraction of retained austenite is increased with increasing the austempering temperature. This is because of the decrease in nucleation potential of ferrite platelets due to the decrease (b) austempered at 330/359 °C in the cooling rate during quenching.

US demand for materials used in batteries and fuel cells is expected to decline to $4.3 billion in 2013, largely as a result of a moderation in raw material prices, particularly lead, which increased at double-digit rates during the 2003-2008 period. In particular, growth will be bolstered by an accel- eration in lead-acid battery output as motor vehicle production recovers. The continued popularity of high- drain electronic devices will provide favorable opportunities for metals, chemicals and other materials. Metals will continue to be the leading material type in batteries and fuel cells largely as a result of the enormity of the lead-ac- photo: METALL id motor vehicle battery market.
