Latest Patent Applications
One of his notable patent applications is titled "Process for Manufacturing Stainless Steel Containing Fine Carbonitrides, and Product Obtained from This Process." This invention relates to a process for manufacturing a semi-finished product made of stabilized stainless steel. The process includes a casting step using a hollow jet nozzle placed between a tundish and a continuous casting mold. The nozzle features a distributing member that deflects the liquid metal arriving at its inlet, creating an internal volume devoid of liquid metal in the hollow jet. A non-stabilized stainless steel, which contains no nitride, carbide, or carbonitride precipitates, is delivered in liquid metal form into the tundish. The liquid metal is cast through the nozzle while simultaneously adding metal powder into the internal volume of the hollow jet. This metal powder contains at least one element for stabilizing the stainless steel, with the addition occurring at a temperature between T+10° C. and T+40° C. The liquid metal solidifies, starting less than 2 seconds after the addition, to obtain the semi-finished product.
Conclusion
Jean-Michel Damasse's innovative approach to stainless steel manufacturing showcases his expertise in the field. His contributions, particularly through his latest patent application, highlight the potential advancements in stainless steel production.
