Recycling of Magnesium Chips and Sludge - A Solution Serving the Magnesium Die Casting Industry

摘要

Increasing usage of magnesium alloys and especially new applications with creep resistant alloys in the car industry in Europe will create huge amounts of chips in the future. This will start in 2005 and change the situation in the European Mg die casting industry in terms of handling these residues in a safe and economic way. In addition increasing recycling capacities will create more Mg sludge. Both chips and sludge have to be treated in a safe, environmental friendly and economical manner to secure the future of Mg growth. Hydro Magnesium and partners have developed new processes to treat these Mg residues and plan to set up a facility in Germany to serve the European Mg die casting industry. The concept as well as the processes and markets are described in this paper.
