The coating of metal strips with tin or aluminium, enamelling, melting of aluminium blocks or sintering of metallic inks requires very high temperatures. Such heating processes need a lot of energy, time and space. Heraeus Noblelight is offering the MAX infrared oven for heating processes requiring very high temperatures.

The oven combines infrared radiation with convection and extremely high reflection. It can be matched exactly to the process, which reportedly makes it more robust and stable than a conventional oven. This allows capacity to be increased and quality to be improved.

In order to change the structure of metals, such as complex aluminium trims in motor vehicles, it is necessary to heat aluminium or magnesium components to very high temperatures. The heating of highly reflective metals is a challenge for conventional technologies. Up to 90 per cent of the energy input can be lost by reflection or transmission. According to Heraeus, thanks to the MAX infrared technology, an energy efficiency of up to 90 per cent can now be achieved for these tasks, depending on the particular application and the oven design.

Tests with various customers in the company’s in-house applications centre have delivered very excellent 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.

Heraeus will showcase a range of infrared systems for metal processing on Stand C01 in Hall 9 at the Thermoprocess Exhibition in Duesseldorf from 16–20 June.

Key features and benefits

  • 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 Quartz Reflective Coating (QRC) nano-reflectors. The QRC is essentially an opaque, white, quartz glass. The nanostructure imparts a diffuse-reflective capability to the material, resulting in a high homogeneity of the temperature field in the oven. 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 infrared systems are flexibly tailored to meet customer requirements, in order to achieve the highest possible energy efficiency for the process.
  • All MAX infrared ovens share a compact design and construction, so 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 increases energy efficiency and reduces operating costs.
  • MAX oven elements can be arranged one behind the other in a modular fashion. They can then be individually controlled, enabling, potentially, very fast product changeover. The compact ovens can also combined with conveyor systems.
