Title: Innovations of Jean Driole in Electroconductive Material Melting
Introduction
Jean Driole is a notable inventor based in Grenoble, France. He has made significant contributions to the field of materials science, particularly in the melting and casting of electroconductive materials. With a total of three patents to his name, Driole's work showcases innovative processes that enhance the efficiency and effectiveness of metal melting techniques.
Latest Patents
One of Driole's latest patents is a process for melting an electroconductive material in a cold crucible. This process involves electromagnetically confining a mass of the electroconductive material up to its melting temperature. The method includes creating at least one vortex in the liquid material to include particles contained within it. The vortex is generated through electromagnetic stirring, which ensures a uniform melting process. Additionally, the liquid electroconductive material is poured through a tube that is subjected to radial electromagnetic confinement, maintaining a vertical coaxial alignment of the electromagnetic fields.
Another significant patent is for an apparatus designed for melting and continuously casting metals. This apparatus features a vertical, conductive cold crucible with insulated longitudinal sectors that allow for efficient cooling. The inductor coils surrounding the crucible provide both heating and confinement of the metal. This innovative design is particularly advantageous for melting and casting refractory metals and other challenging materials.
