Title: Innovations of Gilles Nussbaum
Introduction
Gilles Nussbaum is a prominent inventor based in Grenoble, France. He has made significant contributions to the field of metallurgy, particularly in the development of desulfurizing agents and magnesium alloys. With a total of seven patents to his name, Nussbaum's work has had a considerable impact on the industry.
Latest Patents
Nussbaum's latest patents include a desulfurizing agent for cast iron, which comprises calcium carbide. This product is designed for the desulfurization of liquid cast iron and is composed of technical calcium carbide powder. It may also include additives that promote gaseous release in the bath and modify the composition of the slag. The product is coated or agglomerated with resins or organic compounds that have a clear melting point and remain solid at ambient temperature. The process involves mixing the carbide and additives with a binding agent, agglomerating by pellet formation, and possibly grinding and sifting to achieve the desired granulometry. This innovative product is added to liquid cast iron using a lance, by gravity, or as a filled wire, offering good pourability, increased effectiveness, and reduced reactivity to moisture. Additionally, Nussbaum has developed a method for improving the performance of magnesium alloys, which involves forming cast magnesium-based alloy articles with reduced microshrinkage.
