  • Method for continuous casting of a metal with improved mechanical strength and product obtained by said method
    Patent number: 9004150
    Abstract: A new method for continuous casting of molten metal is provided that allows one to obtain an intermediate product such as slab, billet wire, etc. before subsequent thermomechanical treatment (e.g. lamination or annealing), such that its chemical composition is modified by the addition of elements in order to give it greater mechanical strength.
    Type: Grant
    Filed: June 2, 2011
    Date of Patent: April 14, 2015
    Assignee: Centre de Recherches Metallurgiques ASBL—Centrum Voor Research in de Metallurgie VZW
    Inventors: Paul Naveau, Astrid De Ro

  • Method for Continuous Casting of a Metal with Improved Mechanical Strength and Product Obtained by Said Method
    Publication number: 20090266506
    Abstract: The invention concerns a method for continuous casting of a metal in the form of a hollow jet into a nozzle arranged between a pouring ladle or a tundish and a continuous casting ingot mold, said nozzle including in its upper part a dispensing member capable of deflecting at least part of the liquid metal reaching the nozzle inlet towards an inner wall of the nozzle before it penetrates into the ingot mold. Said method includes injecting into an inner volume of the hollow jet finely-divided solid material, characterized in that the finely-divided solid material comprises technical ceramic nanoparticles, of characteristic size less than 200 nm and preferably less than 100 nm.
