For a new process
Gmunden’s acid test inside the Erzberg
Some people know the Erzberg because of the Enduro motorcycle race, others because it is simply indispensable as a supplier of rock. What few people know: There is also a research center inside the mountain. Rauch Furnace Technology from Gmunden ventured into a tunnel to test a new smelting process for magnesium.
The Erzberg in Styria: where around 12 million tons of rock are mined every year, Rauch Furnace Technology GmbH already feels a little at home. The specialist for the construction of plants and industrial furnaces took a look behind the scenes of the largest open-cast mine in Central Europe during its 2023 company outing, but is also frequently in Eisenerz for work assignments. The project, which was recently awarded the Upper Austrian State Prize for Innovation, even took the company into a tunnel that is actually used for research into tunnel construction.
In the "Zentrum am Berg", which is part of the Institute for Subsurface Engineering at the University of Leoben, the Gmunden-based company set up a magnesium melting furnace including a casting test facility.
What was tested there? A process developed by Rauch Furnace Technology, thanks to which the use of shielding gas mixtures in magnesium melting operations can be optimized and any critical conditions can be detected before they occur!
Fewer emissions
The process improves our carbon footprint by reducing emissions. Lower shielding gas consumption also means cost savings. Magnesium is on the rise as a material for lightweight components for the automotive industry and aviation. The development from Gmunden should be particularly popular with companies specializing in recycling.
