  • Patent number: 10041146
    Abstract: Processes for producing low-nitrogen metallic chromium or chromium-containing alloys, which prevent the nitrogen in the surrounding atmosphere from being carried into the melt and being absorbed by the metallic chromium or chromium-containing alloy during the metallothermic reaction, include vacuum-degassing a thermite mixture comprising metal compounds and metallic reducing powders contained within a vacuum vessel, igniting the thermite mixture to effect reduction of the metal compounds within the vessel under reduced pressure i.e., below 1 bar, and conducting the entire reduction reaction in said vessel under reduced pressure, including solidification and cooling, to produce a final product with a nitrogen content below 10 ppm. The final products obtained, in addition to low-nitrogen metallic chromium in combination with other elements, can be used as raw materials in the manufacture of superalloys, stainless steel and other specialty steels whose final content of nitrogen is below 10 ppm.

  • Patent number: 10011892
    Abstract: Methods are provided for producing alloy forms from alloys containing one or more extremely reactive elements and for fabricating a component therefrom. The fabricating method comprises substantially removing a reactive gas from the fabrication environment. An alloy form of the alloy is formed. The alloy form is formed by melting the alloy or by melting one or more base elements of the alloy to produce a molten liquid and introducing the one or more extremely reactive elements into the molten liquid. The molten alloy is shaped into the alloy form. The component is formed from the alloy form. If the one or more extremely reactive elements are introduced into the molten liquid, such introduction occurs just prior to the shaping step.

  • Patent number: 10012443
    Abstract: A vessel used for containing molten metal has a refractory liner with an exterior surface and a metal-contacting interior surface and is made of at least two refractory liner units abutting at a joint. A housing at least partially surrounds the exterior surface of the refractory liner with a gap present between the exterior surface and the housing. Molten metal confinement elements, impenetrable by molten metal, are positioned within the gap to partition the gap into a molten metal confinement region between the elements and at least one other region. For example, the other region may be used to hold equipment such as electrical heaters that may be damaged by contact with molten metal. A drain outlet positioned in the housing allows molten metal entering the gap to drain out of the gap at the drain outlet.
