Abstract

The invention discloses a titanium-based powder material preparing device. The titanium-based powder material preparing device is characterized by at least comprising a vacuum chamber, a magnetic levitation melting furnace, an atomizing chamber and a powder collecting unit, wherein the upper part of the vacuum chamber is provided with a feeding chamber; the magnetic levitation melting furnace is arranged inside the vacuum chamber; the atomizing chamber is arranged under and integrally connected with the vacuum chamber; the power collecting unit is composed of a powder collecting chamber arranged under the atomizing chamber. During application, after the magnetic levitation melting furnace is electrified by high-frequency alternating current, a high-frequency alternating magnetic field canbe generated in the space surrounding a coil and produce induced eddy current inside furnace materials, the induced eddy current interacts with an external alternating magnetic field to produce levitation force of the furnace materials, and the materials can be in a suspended state through the levitation force and by self-gravity; meanwhile, an eddy current loop can produce a large amount of heatto rapidly melt the furnace materials, and under the action of electromagnetic stirring, deslagging, degassing and purification are conducted; by controlling the magnetic field, the purified molten materials fall down into the atomizing chamber, and by means of a supersonic high-pressure argon atomizer and a cooling device, can be atomized into titanium-based powder.
