| 20100278684 | PROCESS FOR MANUFACTURING STAINLESS STEEL CONTAINING FINE CARBONITRIDES, AND PRODUCT OBTAINED FROM THIS PROCESS - The invention relates to a process for manufacturing a semi-finished product made of stabilized stainless steel, which includes a casting step by means of a hollow jet nozzle placed between a tundish and a continuous casting mould. The nozzle comprises, in its upper part, a distributing member for deflecting the liquid metal arriving at the inlet of the nozzle, thus defining an internal volume with no liquid metal in the hollow jet. A non-stabilized stainless steel containing no nitride, carbide and carbonitride precipitates, is delivered in liquid metal form into the tundish. The liquid metal is cast by means of the nozzle, simultaneously carrying out an addition of metal powder into an internal volume of the hollow jet. The metal powder contains at least one element for stabilizing the stainless steel, the addition being carried out at a temperature between T | 11-04-2010 |
