Title: **Oddmund Wallevik: A Pioneer in Magnesium Processing Innovations**
Introduction
Oddmund Wallevik, an accomplished inventor based in Porsgrunn, Norway, has made significant contributions to the field of magnesium processing. With a total of five patents to his name, Wallevik's work focuses on advanced methods and apparatuses that enhance the efficiency and quality of magnesium production.
Latest Patents
Wallevik's latest innovations include two notable patents. The first is a **method and apparatus for remelting and refining magnesium**, which allows both the melting of ingots and the remelting of return metal. This innovative process involves pumping overheated salt melt from a heating zone in a salt melt furnace and distributing it over the metal in a basket positioned above the liquid level. As the metal melts, it can be efficiently removed from the basket without further heating, utilizing a melt composition rich in calcium chloride with calcium fluoride content.
The second patent is the **cathode for magnesium production**, which serves a critical role in the electrolysis of molten salts. This cathode comprises compact materials like molybdenum, tungsten, or their alloys. Alternatively, it can consist of a substrate coated with these metals. The design ensures improved wetting of the cathode by magnesium, leading to a reduction in contaminants in the produced metal. The coating thickness is specified to be between 10 to 20 micrometers, enhancing the efficiency of magnesium production.
