SFI Metal Production at Materialdagen
Dr. Daniel Perez Clos successfully defended his thesis May 26th. Daniel did an excellent presentation of the trial lecture: “Mechanisms of ash transport and adhesion on cylindrical tubes in crossflow" followed by the presentation of his PhD thesis “Formation of Hard Grey Scale (HGS) on the Surface of a Cold-finger in the Aluminium Production Industry”.
The MOLTEN 2021 Conference was organized February 21-25, 2021. Several SFI Metal Production members contributed with presentatations at the conference. MOLTEN 2021 was a virtuel event and all presentations had to be recorded and made available at the virtual conference platform. SINTEF researcher Vincent Canaguier's presentation turned out to be one of the top 5 most viewed presentations! The title of his presentation was Foaming during silicomanganese reduction.
The organizer writes that Vincent's enthusiastic presentation helped to make the event a great success! A prize (USD 100) will be transferred to the winner. Congratulations to Vincent!
Attila Kovacs has successfully defended his thesis for Doctor of Philosophy at Oxford University. Attila has been working on fundamental mathematical modelling of alumina dissolution. Highlights from his work involve the identification of characteristic time scales for the freezing-melting-dissolution process as well as determining under which conditions alumina rafts may form. The supervision of Attila has been a successful joint venture between scholars at Oxford and NTNU as well as key researchers in Hydro and NORCE.
Congratulations to Dr. Kovacs!
The Horizon 2020-project SisAl Pilot is coordinated by SFI Metal Production Professor Gabriella Tranell. The project has now made a video that gives information about the innovative pilot.
Enjoy watching the video available on the project website.
The project is an innovative pilot for Silicon production with low environmental impact using secondary Aluminium and silicon raw materials. The project aims to demonstrate a patented novel industrial process to produce silicon (Si, a critical raw material), enabling a shift from today’s carbothermic Submerged Arc Furnace (SAF) process to a far more environmentally and economically sustainable alternative: an aluminothermic reduction of quartz in slag that utilizes secondary raw materials such as aluminium (Al) EoL scrap and dross, as replacements for carbon reductants used today.
The SFI centre funding period is coming to an end in the beginning of 2023. It is important to start the in-depth discussions on how to ensure that the good results and strong research groups are maintained and prolonged. Our ambition is to develop a new SFI project based on the strong fundament of SFI Metal Production. March 2nd we organized a strategy seminar for the SFI Management team on this topic.
SINTEF and NTNU are partners in a newly awarded EU financed project called HARARE. The project will demonstrate sustainable pathways to produce metals using hydrogen as an enabler. Hydrogen as a reductant to substitute carbon is one of the few ways metallurgical industry can potentially become truly free of CO2-emissions.
In 2019, it was estimated that only about 5 % of lithium-ion batteries were recycled. The market for lithium-ion batteries is expected to grow tenfold the coming decade, mostly driven by the growth in the number of electrical vehicles. The low recycling rate and the high growth demonstrates the need for increased focus on recycling and improved recycling technologies. A team of scientists from SINTEF will the coming year be working on innovative solutions for recycling of batteries. Their new ideas spring from their wide experience in recycling of metals and molten salt electrochemistry. SINTEF is financing the project so that new inventions can be patented by SINTEF. Anne Kvithyll, Research Domain leader in SFI Metal Production, is the contact person to this project.
Every 5-10 years NTNU professors are excused of their teaching duties and have the possibility to visit other universities, or cooperating partners, to gain insight. 2020 was the year that Professor Merete Tangstad planned to go to China and Japan to spend some time at University of Science and Technology Beijing and University of Tokyo. Read about Merete’s experience with sabatical 2020, in her own words:
A Roundtable Discussion: Challenges for a Sustainable Aluminum Industry and Advice for the Next Generation
Do you wonder what five well-known specialists both from primary and secondary aluminium industry think is the most critical challenges how we might face them? Then you should read the report from the discussion initiated by SFI RD leader Anne Kvithyld that is printed in the October issue of The Journal of The Minerals, Metals & Materials Society, JOM. You will notice the more optimistic view from China than USA and Europe. And last but not least you will find out what people late in their carriers would have liked to know when they started.
This Autumn researcher Kurian Vachaparambil has joined SFI Metal Production to work in close collaboration with Kristian Etienne Einarsrud (IMA, NTNU) and Halvor Dalaker (SINTEF Industry). The aim of the project is to develop a simulation framework which can be used to simulate industrially relevant reactive flow simulations which can treat both fluid dynamics, heat transfer and chemical reactions.
Simulating of chemically reactive flows are difficult due to the complex coupling between fluid flow, heat transfer and chemical reactions. Modelling these phenomena can provide knowledge to understand the operation of experimental and industrial reactors as well as in developing strategies to optimize these processes like by reducing NOx generation.
Kurian recently submitted his PhD thesis at the electrochemistry group at IMA, NTNU. In his PhD he focused on developing multiphysics solver for electrochemical gas evolution on OpenFOAM.
SFI Metal Production at Materialdagen
18 October, 2016 - On Wednesday October 5th, Aud Wærnes, the SFI Metal Production director, gave a lecture at Materialdagen where she presented the center. She talked about the different research domains and what they focus on, the general struction of the center and it’s vision and goals for the future years.
Materialdagen is a career day arranged by the 3rd year students in the Materials Science and Engineering Masters Program. It is an opportunity to build bridges between students and companies with a shared interest in materials and has been arranged every year since 2009. This year the event took place over two days, October 5th and 6th, and other lectures included presentations from SIINTEF, The Institute for Material Technology at NTNU, Elkem and Hydro, all partners at the SFI.
