Special: Energy, Resources, Environment and Sustainability

Energy and resource efficiency, environ­mental compatibility and sustainability of production and consumption are general requirements on today’s economy and society. The December Special focuses on corresponding articles related to alumin­ium production and processing including application examples.

Otto Fuchs orders multi-chamber melting furnace from Hertwich

Otto Fuchs expands its casthouse in Meinerzhagen, Germany, with a Ecomelt-PS150 melting furnace and two tilting holding and casting furnaces from Hertwich Engineering. The new recycling furnace will be the fifth Ecomelt unit and with a capacity of 7,7 tonnes per hour the largest one at Otto Fuchs. Both casting furnaces, which are also part of the scope of supply, are designed for a capacity of 20 tonnes. This order maintains the successful partnership between Otto Fuchs and Hertwich, which already exists for more than 15 years.

 

 

 

Steinert succeeds in reducing the magnesium proportion when processing aluminium scrap

Increasing the aluminium purity and handling the specifically defined alloy concentrations in a targeted manner are becoming increasingly important when processing varied scrap aluminium. The proportions of free magnesium contained in the material flow of some aluminium scrap can now be reduced by up to 92%. This technical application can be retrofitted on most Steinert XSS T x-ray transmission sorting systems built from 2016 and is already being used.

 

New Tomra machine sorts even smallest metal parts

Tomra Sorting Recycling has recently launched the X-Tract X6 Fines for the high-purity sorting of mixed non-ferrous metal fractions. The new machine can detect and sort grains of metal of almost half the size of what was previously sortable. This capability has been achieved by developing Tomra’s field-proven high-speed x-ray transmission (XRT) technology.

 

 

Aluminium cycle: machining, briquetting, melting

Photo: Ruf

The aluminium recycling cycle begins and ends in melting plants. In between, this light metal is machined in many different industrial operations of diverse sectors and then ideally pressed into a compact briquette using a briquetting system from the German company Ruf in Zaisertshofen. But where exactly are chips produced and why does briquetting usually make economic sense? The article provides answers to these questions.

 

 

New Life Cycle Assessment of aluminium beverage cans

Metal Packaging Europe, the association of European producers of rigid metal packaging and their supply chain partners, have completed a new Life Cycle Assessment (LCA) of aluminium beverage cans (25, 33 and 50 cl volumes). The study shows, that carbon emissions have been significantly reduced within ten years. It is fitting, therefore, that the recycling rate for aluminium beverage cans has reached a new high in Europe.

 

Innovative log preheating concept saves energy and costs

The extrutec GmbH in Radolfzell on Lake Constance distinguishes itself by continual new and further development of its products for extrusion plants together with marked proximity to both the market and its customers. This can also be seen in the latest new development: the Extrutec Eco Shower Unit (ESU). This is a patent-pending, water-heated log preheater, integrated in the charging roller conveyor in front of the preheating zone of the gas furnace. The technology offers significant energy and economic advantages over conventional log preheating.

From 14 to 16 January 2020, the Euroguss trade fair will take place in Nuremberg, providing an insight into the state of die casting technology and digitization in the industry. Our journal takes up the fair event with various foundry-related topics.

 

Innovative exhaust air technology for die casting machines

In modern production plants, clean air in the working area is an absolute must. The exhaust air generated by foundry machines is composed of oily smoke and aerosol substances. The continuous use of these machines results in a high smoke pollution, which has to be separated. Therefore, exhaust air technology in modern foundries offers high potentials for energy savings and CO2 avoidance. When expanding its production site in Žiar nad Hronom, Slovakia, automotive supplier Nemak relied on a modern exhaust air filtration system from KMA Umwelttechnik in Germany.

 

 

Magmasoft – autonomous Engineering

The Magma GmbH has introduced its new release Magmasoft 5.4.1, which offers numerous new capabilities and improvements for virtual prediction and optimization for all casting processes, including continuous casting and core production.

 

30 years of light metals foundry in BMW Landshut plant

Thirty years ago, in January 1989, the light metals foundry in the BMW plant in Landshut, Germany, started production. Since then, many BMW Group automobiles and motorcycles have been made with castings from Landshut. Casting technology has become an important growth engine for the site. The light metals foundry has undergone continuous development – including the recent digitization of its maintenance and the 3D printing of sand cores for series casting.
