20110250090 | METHOD FOR CONTINUOUS CASTING OF A METAL WITH IMPROVED MECHANICAL STRENGTH AND PRODUCT OBTAINED BY SAID METHOD - 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. | 10-13-2011 |
20090301338 | Projectile Made Of Steel Softened To The Core - The present invention relates to a process for manufacturing a projectile made of steel or based on iron, for a hunting or sports cartridge, for the purpose of giving it a Vickers hardness at room temperature of between 40 HV 10 and 110 HV 10, preferably between 40 HV 10 and 85 HV 10, characterized at least by the following successive steps:—liquid pig iron or steel is used, hereafter called liquid metal, the carbon content of which is between 0.8 and 4.0% C by weight, preferably between 0.8 and 2.0% C by weight;—the liquid metal is cast using a steam or water-vapour granulation process to obtain spheroidal steel particles;—said particles are subjected to a heat treatment for softening the solidified metal by graphitization, while remaining in the ferritic range; and—optionally, said particles are subjected to a surface coating treatment. | 12-10-2009 |
20090266506 | Method for Continuous Casting of a Metal with Improved Mechanical Strength and Product Obtained by Said Method - 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. | 10-29-2009 |
