Title: Innovations of Pierre Vayssiere
Introduction
Pierre Vayssiere is a notable inventor based in Metz, France. He has made significant contributions to the field of metallurgy, particularly in processes involving molten metal. With a total of five patents to his name, Vayssiere's work has had a lasting impact on industrial practices.
Latest Patents
One of Vayssiere's latest patents is a process for periodically and pneumatically stirring a bath of molten metal. This innovative method involves injecting a gaseous fluid below the surface of the molten metal to prevent blockage of the injection devices during periods when stirring is not required. When stirring is necessary, a liquid fluid that vaporizes quickly upon contact with the molten metal is injected, optimizing the mixing process with minimal devices. This process is particularly advantageous in converters for pneumatically converting pig iron into steel, where oxygen is blown onto the molten metal bath.
Another significant patent is for a refractory piece permeable to gases. This invention is designed to be incorporated into the inner refractory lining of a metallurgical container. One surface of the piece is in contact with the molten metal, while the opposite surface has means for introducing gas under pressure. The piece consists of nonporous refractory material with local discontinuities that allow for the desired gas flow into the metal bath. This design ensures durability and efficiency, matching the lifespan of the surrounding refractory lining.
