Extremely efficient heating of metals with the MAX infrared oven from Heraeus

08.05.2015

The coating of metal strips with tin or aluminum, enameling, melting of aluminum blocks or sintering of metallic inks requires very high temperatures. Such heating processes need a lot of energy, time and space.

Heraeus Noblelight offers the “MAX” infrared oven for heating process requiring very high temperatures. These ovens combine infrared radiation with convection and extremely high reflection. As a result, they are much superior to conventional industrial ovens.

They can be matched exactly to the process, which makes them more robust and stable. This allows capacity to be increased and quality to be improved. And these more efficient ovens save space, time and energy. Heraeus Noblelight will show infrared systems for metal processing on Stand C01 in Hall 9 at the Thermprocess Exhibition in Duesseldorf from 16 to 20 June.

In order to change the structure of metals, such as complex aluminum trims in motor vehicles, it is necessary to heat aluminum or magnesium components to very high temperatures. The heating of highly reflective metals is a real challenge for conventional technologies.

Up to 90% of the energy input can be lost by reflection or transmission. Thanks to the new MAX infrared technology, an energy efficiency of up to 90% can now be achieved for these tasks, depending on the particular application and the oven design.

Tests with various customers in our in-house Applications Centre have delivered very impressive results. Compared with conventional electrical heating methods, the heating process with a MAX oven was three times faster for metals. At the same time, energy consumption was only one fifth.

Advantages over standard ovens By Using QRC® Material

Tests have shown clear advantages of MAX ovens with QRC over conventional ovens using fireclay as the insulation material. Unlike conventional ovens, MAX ovens can be used in a continuous process, as the process chamber is made completely of quartz glass, which makes the oven resistant to thermal shock and a smaller, more compact oven is possible for the same power rating.

With a MAX infrared oven, the oven inside is comprised exclusively of quartz glass including QRC® nanoreflectors. The QRC® (Quartz Reflective Coating), developed by Heraeus is essentially an opaque, white, quartz glass. The nanostructure imparts a diffuse reflective capability to the material, resulting in a very high homogeneity of the temperature field in the oven.

In addition, quartz glass is also very clean, which is very important in the manufacture of items such as sensors and other sensitive parts in the car industry.

MAX – Exactly Tailored To Customer Needs

MAX infrared systems are flexibly tailored to meet customer requirements, in order to achieve the highest possible energy-efficiency for the process in question.

All MAX infrared ovens share a compact design and construction, so that the input energy is used more efficiently because the infrared radiation is optimally reflected within the oven, while the natural convection is also used.

As a result, process times can be shortened, which significantly increases energy efficiency and reduces operating costs. MAX infrared ovens provide systems solutions. Computer simulation at the design phase also helps to ensure energy efficiency.

MAX oven elements can be arranged one behind the other in a modular fashion. They can then be individually controlled, making possibly very fast product change-over. The compact ovens can also be combined with conveyor systems.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
