摘要： Method and installation for converting a metal in the liquid state into a fragmented metal in the solid state. The metal in the liquid state is poured on an upstream portion of a receiving surface (7) of a first cooled vibrating table (4). The metal falls from the downstream end of the first table on an upstream portion of a receiving surface (17) of a second cooled vibrating table (5). The fragmented and solidified metal is discharged at the downstream end of the receiving surface of that second table. A rotary fragmentation roller (102) may be positioned above a table. The tables comprise an upstream cooling zone (7) by means of a liquid/gas emulsion and a downstream cooling zone (17) by means of a liquid.

摘要： A metallurgical system for producing metals and metal alloys includes a fluid cooled mixing cold hearth having a melting cavity configured to hold a raw material for melting into a molten metal, and a mechanical drive configured to mount and move the mixing cold hearth for mixing the raw material. The system also includes a heat source configured to heat the raw material in the melting cavity, and a heat removal system configured to provide adjustable insulation for the molten metal. The mixing cold hearth can be configured as a removal element of an assembly of interchangeable mixing cold hearths, with each mixing cold hearth of the assembly configured for melting a specific category of raw materials. A process includes the steps of providing the mixing cold hearth, feeding the raw material into the melting cavity, heating the raw material, and moving the mixing cold hearth during the heating step.

摘要： A method for manufacturing metal powder includes: melting at least a portion of a metal starting material in a reaction vessel by utilizing plasma so as to form molten metal; evaporating the molten metal so as to produce a metal vapor; and transferring the metal vapor from the reaction vessel to a cooling tube together with a carrier gas supplied into the reaction vessel so as to cool the metal vapor, and condensing the metal vapor in the cooling tube, thereby producing metal powder. The method further includes supplying an oxygen gas into the reaction vessel.
