A gas inerting system and method is provided. This system includes a rotary melting furnace with a furnace barrel, a burner, and a charge of metal to be melted; and an injection manifold with a plurality of injection orifices. The burner is configured to produce a flame directed into the furnace barrel, and the plurality of injection orifices are configured to disperse inert gas streams into the furnace barrel, into an inerting region between the burner flame and the charge of aluminum. The metal to be melted may be aluminum. The method of inerting includes rotating the rotary furnace and introducing heat into the furnace barrel by generating the flame, thereby beginning a melt cycle, then introducing the inert gas streams into an inlet to the injection manifold, thereby directing the inert gas streams through the injection orifices and into the inerting region, after a predetermined condition has been met.

In a method of manufacturing metal powders in a continuous type, metal is heated at a temperature greater than a melting point to form a liquid phase metal, and the liquid phase metal and an emulsion carrier, which is emulsified without reacting with the liquid phase metal, are supplied into a container, and the liquid phase metal and the emulsion carrier are emulsified through Taylor flow to form an emulsion solution. The emulsion solution is discharged from the container, and then, the emulsion solution is cooled at a temperature smaller than the melting point to selectively solidifying the liquid phase metal in the emulsion solution to form the metal powders.

A furnace has a melting chamber with a periphery defined by a surrounding wall structure. The furnace is provided with a purge system configured to direct inert gas to flow downward in the melting chamber in the configuration of a curtain that adjoins the wall structure and reaches only partially around the periphery of the melting chamber.

A tilting converter comprising a container (2), defining a first longitudinal axis X, having a bottom (2); a support ring (3), coaxial to the container (2) and distanced from said container, provided with two diametrically opposite supporting pins (6), defining a second axis Y orthogonal to the first axis X, adapted to allow a rotation of the converter about said second axis Y; a suspension system, connecting said container (2) to said support ring (3), comprising groups (12) of first suspension devices (7), said groups (12) being arranged substantially equidistant to each other along a cylindrical side surface coaxial to the first axis X, in a position between the support ring (3) and the bottom (2); each of said first suspension devices (7) being provided with a plurality of longitudinal elastic elements, each longitudinal elastic element being arranged alongside the next so as to define a laying plane, and a gap (15, 15) is provided between one longitudinal elastic element and the next.
