Research » Aluminum Recycling and Melt Purification
The working group focuses on the recycling of aluminium scraps via under salt or salt-free processes. Top Blown Rotary Converter (TBRC) in lab and demo-scale is used to perform the experiments. Efficient coagulation during recycling is also studied by using different salt compositions. In addition, thermal treatment of organic containing materials is being investigated to find an optimum process which is a combination of pre-treatment and recycling.
Moreover, the working group performs investigations about the melt cleanliness by using different removal and detection technologies to meet the high requirements of the product and material properties. Fundamental researches on particle behaviour in melts such as settling and agglomeration are also on-going to gain more knowledge about particles. Improvement of existing technologies and understanding of the mechanisms are main targets of the activities.
