Future technology made by hpl

hpl-Group presents casting rolling mill for magnesium wire.

At the end of August 2017, hpl-Neugnadenfelder Maschinenfabrik GmbH invited to the official presentation of a pilot research line for the economic production of magnesium wire. A new procedure is implemented here which hpl-Neugnadenfelder has developed in cooperation with the German university “Technische Universität Bergakademie Freiberg”. The line will be put into operation at the beginning of autumn 2017 and combines two basic processes for the production of magnesium wire which had been carried out separately so far: the casting of 700°C hot, melted magnesium solidifying abruptly in the rolling gap as well as the forming of this solidified magnesium profile in the rolling gap. Inside the material, new structures are then formed having a positive influence on the material properties and the forming ability in the following processes. This procedure provides a future-oriented basis for further researches at the university in Freiberg aimed at the innovative production of magnesium wire – a material that is expected to play an important role in the future revolutionizing especially the automotive and transport industry. Professor Dr. Kawalla, prorector for Research at the university in Freiberg, emphasizes the future importance of magnesium in different areas of everyday life. If good results are obtained from the research activities which start directly after the line will have been put into operation, many new products will enter the market within several years. This wire could be used to manufacture high-strength bolts, special filler wires or to fix fractures in the field of medicine.

Intensive weeks and months of line development and engineering had been passed before the casting rolling mill has fulfilled all requirements and met all expectations and could be presented officially to the invited guests. Project manager Günter Veldmann and sales manager Hans-Joachim Biedermann both emphasized the special layout of the research line differing extensively from standard rolling mills. The rolls of the casting rolling mill for magnesium wire are not positioned between the mill housing as usual. In the engineering phase, hpl has put a special focus on the research-intensive application and has positioned the rolls outside the mill housing construction which enables the operators to make fine adjustments without any difficulties for optimizing the production process. Especially this aspect was appreciated by the guests of the university in Freiberg.        

The delight and pride of all project participants was clear for all to see as the casting rolling mill for magnesium wire was finally unveiled to the invited customers, suppliers, politicians and guests of the Chamber of Industry and Commerce in Osnabrück. A lively discussion about the line layout and technology development of the magnesium wire followed.
