Description
Technical Field

Background
The 3D printing metal material is widely applied to the fields of aerospace, chemical engineering, medical appliances and the like. At present, the main methods for producing metal powder by domestic enterprises are vacuum gas atomization (VIGA), electrode induction melting gas atomization (EIGA), Plasma Rotating Electrode (PREP) and Plasma Atomization (PA). The production efficiency of the gas atomization method is high, but the particle size distribution range of the prepared powder product is wide, and the sphericity is poor; the powder product prepared by the plasma rotating electrode atomization method has high sphericity and smooth surface, but has larger average particle size and low fine powder yield.
The plasma atomization method utilizes the heat energy of high-temperature high-speed plasma jet flow to melt metal materials, then utilizes the mechanical energy of the jet flow to crush and atomize the molten metal, and the atomized liquid drops are finally condensed into spherical particles under the action of surface tension in the falling process. The produced powder has the advantages of centralized particle size distribution, good fluidity, high purity and the like. But the plasma atomization method is less energy efficient. The reason is that a large amount of heat is required for melting the metal material, the contact time of the material with the plasma jet is extremely short, the heat energy of the plasma jet is not sufficiently used for heating the material, and an additional auxiliary heat source is required.
The patent CN108025364A adopts a one-wire three-torch-wire structure, metal wire materials are preheated by induction heating, and the unit energy consumption is 31.2 kWh/kg; patent TW202012074A used a one-torch two-wire torch-wire configuration, and the specific energy consumption was reduced to 4 kWh/kg by preheating the metal wire material using arc heating. Titanium alloy is generally non-magnetic or weak magnetic, and only can generate heat by eddy current loss by utilizing electromagnetic induction heating, so that compared with a magnetic material, the titanium alloy has low heating efficiency, large power consumption and more complex equipment; the arc heats up faster and more efficiently, but increases the instability of the plasma jet and the arc in the contact area.
