TU Freiberg dedicates new casting rolling mill for magnesium

On 21st March 2018, the new casting rolling mill for magnesium wire of the German university TU Freiberg was officially put into operation. The start button for turning the rolls for the first time in front of an audience was pushed by invited politicians as wells as representatives of TU Freiberg and hpl-group. Having manufactured the reserach line, the hpl-Group has become an important partner in the development of lightweight construction technologies.

21st March 2018 was an important day for the research activities at the TU Freiberg. Focused on the development of lightweight construction technologies, the Institute of Metal Forming invited to the official start-up of a pilot research line for the energy-saving and economic production of magnesium wire. This event represents a milestone in the history of the university since the researched processes to produce magnesium strips and sheets, that have been developed and patented by TU Freiberg, are now used for the production of magnesium wire – according to the university, this has never been tried before in the international market. The new technology opens up new innovative possibilities for the production of components and machine elements in the fields of mechanical engineering, vehicle and tool manufacturing. Applications in the field of architecture as well as for the production of implants in medical science complete the fields where magnesium as lightweight material could play an important role in the future. “The new research line allows our students and researchers to learn and study in a practical environment”, declares Prof. Dr. Kawalla, prorector for Research at the university in Freiberg.  

The manufacture of the pilot research line has again been contracted to the hpl-Group which already delivered the strip running components of a pilot research line for the production of magnesium strips and sheets in 2010. “The cooperation between TU Freiberg and hpl-Group has always been very close both in the past and nowadays. The new research line has been developed in close cooperation with TU Freiberg within a tight schedule and delivered just in time”, confirms Günter Veldmann, project manager of the hpl-Group.

In front of approx. 50 guests from politics, business and science, Günter Veldmann and Thorsten Dirks, general manager of the hpl-Group, were invited to join the representatives of TU Freiberg and the politics pushing the red button to put the line officially into operation. For safety reasons, magnesium was not cast at that time, but the invited guests have nevertheless got a very good impression of the research-relevant considerations and state-of-the-art technology that have been thoroughly considered by the hpl-Group during the development and manufacture of the line.

21st March 2018 is considered by TU Freiberg as an important milestone in the economic production of magnesium wire. “We plan to produce first semi-finished products in the foreseeable future”, declares Prof. Dr.-Ing. Ulrich Prahl, professor for metal forming at TU Freiberg. Semi-finished products, such as wire, are finished in many different industries. If the test runs are successful, the line is planned to be run in continuous operating conditions.
