Many talk about saving energy. But are we doing everything that is possible?
There are even more options. For example, Germany makes a large amount of
energy with combustible energy. Switzerland also with about 40% nuclear
power. Why not save, if there are still new possibilities. Here's an
In industry it is common for welded parts to be placed in an oven for
further processing, because of problems with distortion, and to be heated to
approximately 500 to 600 degrees for normal steel. The rule says that for
every 20 mm of thickness, keep the temperature in the oven for one hour.
Depending on the design, such parts often need to be in the oven for 2 days
to 1 week and more. Such an annealing furnace can be imagined as an oven.
The workpieces are kept at the high temperature in the oven. The heating up
we should cool down slowly, otherwise tensions come back into the workpiece.
These stresses must be removed so that these workpieces do not warp during
further processing, which causes a large loss of accuracy. This process
requires a lot of energy. Against this energy expenditure, we have a
solution that allows, instead of heating a workpiece, to relax with
vibration. We call this today MEMV (metal relax with vibration) method, so
that the same goal can be achieved. However, the energy savings are
enormous. With a 12-tonne roller, it takes exactly 460x less energy to
achieve the same result.
AG-Ltd-SA from Switzerland has been relaxing metal with vibration for
many years. An intensive study was started in 2014, so that even better
results can be achieved with new, improved methods. During this time, 3
patent applications were made, which deal with metal relaxation with
vibration rather than low-stress annealing. Hundreds of hours of
measurements were taken during the relaxation process.
Many companies already know it today. Many know it, know that such a
thing is possible, but especially companies that want high precision,
are not bad at all, that it does not apply all, because there are also
very big competitive advantages. The defense industry knows that if the
pipes need to be highly accurate, they will only remain accurate if
vibrated before finishing. And vibrating takes almost no energy, because
the workpieces are brought to vibration in a self-resonance, which then
makes the major part of the excitation by the natural vibration. Not
only the defense industry should benefit from the knowledge, but also
the whole industry and thus the whole population, because it saves a lot
of energy. That's one reason why we're submitting this petition.
The industry has had expensive annealing furnaces for decades and, to
amortize them, they also do a lot of contract work. Arguing that their
stoves are being used to capacity, wasting a plethora of energy, which
could be saved with a modern method of change, which would do the
environment very well.
We request and ask the legislation:
There should be a national and international requirement that the
stress-relieving annealing should only be used where vibration relaxation is not
