Thinking out of the box  

Rapid but systematic cooling of Al-alloy ingots with ILTEC

At the moment the fields of application for the ILTEC Technology are further widened, at the Montanuniversität Leoben, Chair of Nonferrous Metallurgy. 

In order to create defined amounts and distribution of precipitation phases in different aluminum alloys, lab scale tests are performed in the labs of the Montanuniversität. With our small ILTEC test facility, the Al-alloy ingots are casted at different cooling rates realized by modification of the mould preheating temperatures and the heat removal with the ILTEC facility. By precise temperature measurements within the casted ingot piece and a subsequent microscopic analyses and mechanical testing, the optimized cooling conditions can be defined. 

Industrial scale implementation of these test results can lead to improved process routes and finally to better qualities of casted aluminum products.


Poly TBRC - Latest generation of copper refining and smelting process

For our customers in Germany and Russia the PolyTBRC is in latest stage of construction

The installation of this special TBRC converter, as a joint project of PolyMet Solutions, SMS group, Urban Gold and Mettop, will allow our customer to increase the recycling capacity of copper scrap whilst, at the same time, improving process quality, efficiency, and safety.

The benefits for our customers when installing of a PolyTBRC can be highlighted:

Improved heat transfer and reaction kinetics in refining and smelting processes.
The oxygen/gas-combustion system produces an intense, stable and compact flame with very efficient heat transfer capabilities and low exhaust volume flow.
Lambda values can be adjusted over a wide range to produce reducing, neutral or oxidizing conditions.
High ration of metals recovery and flexible process performance with good slag-metal separation.
ILTEC cooled lance for injection purposes.

We are looking forward to hearing from you if there are any questions or you need more information regarding our PolyTBRC.


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 of 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,  to create 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.
