Vacuum Melting Inert Gas Atomization Equipment

Working principle of vacuum melting inert gas atomization equipment: Metal or alloy materials are melted under inert gas protection or vacuum condition, and molten metal is poured through insulation tundish system and restrictor diversion pipe into the high-pressure gas atomizer, where metal liquid is crushed and atomized into a large number of fine droplets by high speed gas jet. Droplets solidify into spherical powder particles under the action of surface tension during deposition and cooling. 

Vacuum melting inert gas atomization equipment can manufacture most of the metal and alloy powders which can not be made by water atomization method. The solidification overcomes the segregation phenomenon, so it can meet the requirements of producing many special alloy powders.

Vacuum melting inert gas atomization equipment has the following advantages:

① Ultrafine particle size: Gas atomization technology can manufacture metal powder with high fineness and high specific surface area. This technology is suitable for making high-performance and high-quality powder materials.

② Uniform composition: Metal powder produced by gas atomization technology is with uniform and accurate chemical composition.

③ High production efficiency: The production efficiency of gas atomization technology is higher than that of traditional technology. The optimization of process parameters can further improve the production efficiency, make the powder particle size reach the required range, and meet the needs of different fields.

④ The melting and atomization processes are carried out in a vacuum or inert gas environment, so oxygen and impurity content in the powder can be reduced, and the purity of the powder can be improved.

We can provide 10~1000 kg class vacuum melting inert gas atomization equipment. 

Vacuum melting inert gas atomization equipment is mainly composed of vacuum melting system, atomization system, high pressure gas system, tundish system, discharge system, control system, etc. 

① Combined with high vacuum technology, high temperature melting technology and high pressure gas atomization technology, the vacuum melting inert gas atomization equipment is especially suitable for producing high quality powders and active metals/alloys powder. The produced powders have the characteristics of high purity, low oxygen content, high yield of fine particles, good sphericity, etc.

② The atomizer is the key component of gas atomizing powder making equipment. The design of atomizer is related to the pulverization efficiency of metal powder and gas consumption. The high-pressure gas atomizer designed by our company saves more than 1/4 gas than the traditional atomizer, greatly reduces the gas consumption, and directly reduces the production cost per kilogram of powder.

③ Our vacuum melting inert gas atomization equipment monitors oxygen content in the system in real time during the working process, which is of great help to control oxygen content of powder, and realizes the pressure difference control type flow limiting atomization function, precisely controls atomized metal flow rate, guarantees stable product quality, and reduces the failure of equipment operation.

④ Our vacuum melting inert gas atomization equipment is equipped with video surveillance in the key parts of the equipment, which can observe the operating status of the equipment in time.
