Title: Innovations in Vertical Casting: The Contributions of Jean-Pierre Riquet
Introduction
Jean-Pierre Riquet, an innovative inventor based in St. Geoirs, France, has made significant contributions to the field of metallurgical engineering. With three patents to his name, Riquet has developed advanced techniques that enhance the efficiency and quality of continuous vertical casting operations. His work has implications for the production of aluminum and its alloys, addressing critical challenges in the manufacturing process.
Latest Patents
Riquet's latest patents showcase his expertise in refining casting methods. One notable invention is a process for regulating the level of the line of contact of the free surface of the metal during a continuous vertical casting operation. By applying a periodic magnetic field of variable strength, he effectively controls the interaction between the liquid metal and the mold. This innovation allows for a reduction in the metal's contact height, from h.sub.1 to h.sub.2, ultimately resulting in a cortical region of zero thickness, a fine grain structure without the need for refining agents, and the elimination of pitting.
Another significant patent involves the design of a mold that enables regulation of the contact level with the molten metal. This mold, primarily composed of metal in its lower section, features an electrically insulating coating on the inner surface. It includes an insert made from insulating material and two terminals connected to an alternating current source, effectively managing the height at which the metal contacts the mold's surface.
