Company visit as part of the International Women's Day on March 8

Organised by the “Styrian Economic Chamber/Referat Frau in der Wirtschaft“

In order to encourage especially women to found a company, CFO and co-founder of Mettop, Iris Filzwieser, gave interesting insights about her daily business. The invited women, coming from all different sectors of economy, carefully listened as Iris Filzwieser explained how she manages the balance between being a mother of four children AND running a company.

Everybody got a very positive but also realistic image of entrepreneurial autonomy with the central message that this is never the easy way but “where there is a will, there is way!


Thinking out of the box

Implementation of a parallel flow device in a pickling tank

In September 2016  a completely new and innovative approach to the use of the parallel flow device (PFD) was implemented at Böhlerbleche GmbH & Co KG, Mürzzuschlag, Austria. For a better movement and thus optimised kinetics of the pickling process, the acid circulates through a series of nozzles via a parallel flow device. This provides a perfectly guided flow to ensure a more homogeneous acid distribution. The 16 nozzles guarantee an ideal circulation between the individual steel plates, thus improving productivity as well as achieving a more uniform surface quality.         


Mettop GmbH, founded in 2005, is an independent Austrian engineering company, specialised in the design, optimisation, and engineering of technologies for metallurgical processes. It is active in the field of pyro- as well as hydrometallurgy of non-ferrous metals and recently also started with innovative cooling systems for the iron and steel industry.

The scope of services comprises optimisation solutions in the area of furnace integrity, combining refractory selection and layout, gas purging systems and cooling elements. In the field of hydrometallurgy, a new electrolysis technology - the METTOP-BRX Technology - was developed and is in operation to allow an acceleration of the electrolytic refining of up to 50 percent. For all metallurgical aggregates and equipment, Mettop developed the new and water-free cooling technology ILTEC, that uses an ionic liquid as cooling medium, for creating new pathways towards safe and efficient cooling for the entire metallurgical industry.

In addition, Mettop is internationally active in terms of technical consulting (process optimisation) and operator training for customers in the non-ferrous metals industry, and also assists in the optimisation of risk management in metallurgical plants.
