  • Process and installation for protecting a solid metal against oxidation during rolling
    Patent number: 4727747
    Abstract: A process and an installation for protecting a solid metal against oxidation during a rolling operation. This installation comprises inert atmosphere enclosures supplied with an inert gas and enclosing the waiting table, in the case where the rolling is carried out by means of a strip train, or located on each side of pressure rolls around blanks to be rolled, when the rolling is carried out by means of a planetary rolling mill.
    Type: Grant

  • Process of producing metal powders from a molten metal material
    Patent number: 4521244
    Abstract: A cryogenic fluid in the liquid phase is put in contact with a metal material maintained in a closed treating vessel, the cryogenic fluid which contains the solid particles formed is exhausted from the vessel, and the solid particles are separated from the cryogenic fluid and collected. The metal material is heated by induction heating with a high-frequency current and maintained in levitation in the cryogenic liquid. The process is applicable to the production of ultra-fine powders from metals which are only slightly volatile.

  • Process for producing solid metal particles from a bath of metal
    Patent number: 4518421
    Abstract: The process concerns a selective refining of molten metals or alloys contained in a closed treatment container in the form of a bath 10. A solid or liquid cryogenic body 13 is brought into contact with the surface of the bath of metal 10 so as to convert, by evaporation-condensation, the vapors (vz) of the impurity or impurities to be eliminated from the bath into solid particles (pz) entrained by the vapors (vf) of the cryogenic body, and the bath of metal 10 is simultaneously stirred.
