How math can make for better metals

More than 50 experts on the metallurgical industry met in Kristiansand to discuss how mathematical models can improve metal production. The two-day conference, Mathematical Modelling in Metallurgical Industry, is part of a cooperation within SFI Metal Production, a Centre for Research-Based Innovation (SFI), hosted by the Norwegian University of Science and Technology (NTNU), with SINTEF and Teknova as research partners.

More than 50 experts on the metallurgical industry met in Kristiansand to discuss how mathematical models can improve metal production. The two-day conference, Mathematical Modelling in Metallurgical Industry, is part of a cooperation within SFI Metal Production, a Centre for Research-Based Innovation (SFI), hosted by the Norwegian University of Science and Technology (NTNU), with SINTEF and Teknova as research partners.

 

Mathematical models are used throughout the metallurgical industry to improve production processes in order to increase quality and reduce cost. A better understanding of reactions and material transport within the hot smelters producing different metals, could provide more consistent quality and less productions errors, thus improving competitiveness and profitability.

 

“This conference is an important meeting place for industry and academia, where the industry makes leading researchers understand industry challenges, and scientific partners present new research and findings. One important issue is how physics-based insight and data-driven analysis may complement each other. The conference aims at improving the communication between industry and academia, which will be of great value for both communities,” says Svenn Anton Halvorsen, Chief Scientist, Modelling and Simulation at Teknova (from 1 October part of NORCE Norwegian Research Centre AS).

 

Keynote speakers were Prof. Dr. Dietmar Hömberg from Weierstrass Institute in Berlin, Germany, and Prof. Harald Martens from the Norwegian University of Science and Technology in Trondheim (NTNU). The conference included speakers from South Africa and Iceland, in addition to several presentations from the Norwegian metallurgical industry and research institutions.

 

More details of this conference will be presented in our next newsletter.

Nature Conference

The Nature Conference, Minerals and Materials for a Sustainable Future was arranged in Trondheim September 11-13th. Several persons from SFI Metal Production were involved during these three days. Merete Tangstad was chair for the session Sustainability and responsible resourcing of minerals and materials. Arne Petter Ratvik and Daniel Beat Müller were speakers on the topics Apatite fertilisers production and Monitoring of physical economy, respectively. Norsk Hydro’s Hans Erik Vatne talked about the value chain approach to sustainable production of aluminium products.

The three SFI-professors Ragnhild Aune, Gabriella Tranell and Kristian Etienne Einarsrud presented The future of engineering Stardust, the conference most challenging title. The presentation started far way back, with the Big Bang and the quotation: “Nature did fabulous job in providing raw materials for us…but almost all present as oxides. That’s why we need metallugists!” Then they gave brief overviews and examples of how to produce metals from oxides. The presentation ended with energy and environmental consideration and the three R’s – Reduce, Reuse and Recycle. The SFI Metal Production professors brought their speech to an end with the follow words:

“Matter is finite and part of our earths inheritance unlike energy, which is given to us in plentiful every day. In order to optimise these finite material resources for generations ahead, our mission must be to balance and manage our energy system and resource handling portfolio better.

Today, we use our experiences in materials production and technology to improve our every day life with a rather short sighted view. We calculate and simulate to secure the development of intelligent solutions that involves making production processes more energy efficient with a lower environmental impact, as well as safer and smarter but we often forget the bigger picture.

In other words, we dream of solutions that will help us on our way to a sustainable and better future. It’s time to make the dream reality – and that is or challenge! ”

Mathematical Modelling in Metallurgical Industry – Conference

Design and operation of metallurgical processes have been gradually improved through industrial experience, research, modern process control, new and/or improved measurements, etc. Nevertheless, due to high temperatures and several complexities, the design and operation of the processes are still to a large degree empirically based, and several process variations are not properly understood.

Mathematical Modelling in Metallurgical Industry – Conference

– Kristiansand, 17-18 September 2018 – Scandic Kristiansand Bystranda

Design and operation of metallurgical processes have been gradually improved through industrial experience, research, modern process control, new and/or improved measurements, etc. Nevertheless, due to high temperatures and several complexities, the design and operation of the processes are still to a large degree empirically based, and several process variations are not properly understood.

Mathematical modelling can effectively be applied to improve today’s knowledge and contribute significantly to solve industrial challenges. Much insight can be established by mathematical analysis. The mathematical descriptions will further supply the basis for computations/simulations, applying modern computers and advanced software. Such simulations constitute valuable tools for enhanced process understanding, process improvements and novel innovations.

Another approach is data-driven analysis where available data is analysed to find hidden patterns. Available tools include artificial intelligence, chemometrics, and other techniques for “big data analytics”.

The conference will comprise

  • Industrial needs and challenges
  • Traditional, physics-based, models
  • Digitization, data-driven modelling

One important issue is how physics-based insight and data-driven analysis may complement each other.

The conference aims at improving the communication/dialogue between industry and academia, which will be of great value for both communities.

The conference is arranged by 

  • Teknova, a subsidiary of Norwegian Research Centre, NORCE
  • SFI Metal Production
  • University of Agder
  • Eyde Cluster

We hope to see you in Kristiansand in September!

celebrated today is essentially a mathematical technology.”

Trip to Alcoa Mosjøen

As a part of the transition between our first and second generation of alumina students, a field trip to Alcoa Mosjøen was arranged.

Trip to Alcoa Mosjøen

As a part of the transition between our first and second generation of alumina students, a field trip to Alcoa Mosjøen was arranged.

Guided by Ellen Myrvold in the anode baking plant, Nina Helene Omdahl in the potrooms and Egil Solberg in the cast house we were given the possibility to follow the process streams from raw material to final product - from the docks and back again. Results from the last year were showcased by our BSc students Ingrid Hansen, Andrea Nautnes and Sofie Nilssen Neverdal and MSc student Sindre Engzelius Gylver, followed by good discussions with representatives from Alcoa.

Activities will be followed up already next month with summer- and MSc students Martin Grimstad (FME HighEFF) and Åste Hegglid Follo (SFI Metal Production), further probing the behaviour of critical raw materials in primary aluminium production.
