Water-wall copper crucible vacuum suspension smelting gas atomized metal powder making equipment


The vacuum levitation melting gas atomization powder making equipment uses the principle of intermediate frequency induction heating to melt the metal material under vacuum conditions (or inert gas), and simultaneously uses magnetic extrusion and stirring to push the liquid metal away from the water-cooled copper crucible, in a suspended state , To avoid the crucible pollution of liquid metal. After smelting, the liquid metal flows out through the nozzle at the bottom of the crucible, is atomized by the high-pressure gas and quickly solidifies into powder, which can better control the alloy composition.

Principle and purpose:

The vacuum levitation melting gas atomization powder making equipment uses the principle of intermediate frequency induction heating to melt the metal material under vacuum conditions (or inert gas), and simultaneously uses magnetic extrusion and stirring to push the liquid metal away from the water-cooled copper crucible, in a suspended state , To avoid the crucible pollution of liquid metal. After smelting, the liquid metal flows out through the nozzle at the bottom of the crucible, is atomized by the high-pressure gas and quickly solidifies into powder, which can better control the alloy composition.

Features:

1. It can produce pure titanium, various titanium alloys and high purity refractory alloy powders.

2. The powder prepared by atomization has the advantages of high sphericity, non-segregation and low oxygen addition.

3. By adjusting the process parameters, the oxygen content and particle size of different alloy powders can be optimized.

4. The atomized high pressure gas is in the state of supersonic gas-liquid two-phase flow, which can rapidly reduce the powder temperature and obtain better sphericity.

5. The suspension melting of copper cold wall can avoid the pollution of molten metal caused by crucibles.
