Title: Michel Douchy: Innovating Metallurgical Processes in Solesmes, France
Introduction
Michel Douchy, an innovative inventor based in Solesmes, France, has made significant contributions to the field of metallurgy with his seven patented inventions. His work primarily focuses on methods that enhance the quality and processing of cast iron and steel, thereby impacting the broader steel industry.
Latest Patents
One of Douchy's notable recent patents is a "Method of desulphurizing pig-iron," which addresses the desulphurization process of cast iron produced in a blast furnace before its conversion to steel. This method involves treating the cast iron with a desulphurizing compound, such as sodium carbonate, followed by the introduction of a specialized composite product with an axial zone containing magnesium in powdered or granular form. Additionally, an inert gas can be injected to facilitate the process, ensuring a cleaner and more efficient transition from iron to steel.
Another significant invention is a "Composite article having a tubular sheath containing a compacted powdery or granular material." This article features a tubular metal sheath with a closed fold encompassing compacted material, which is utilized for the treatment of molten steel in ladles. The production process includes forming an open fold along a generatrix of a circular sheath, which is then constricted to close the fold effectively.
