Parameters

1) Application:

It is an atomization pulverizing experimental device designed to meet the production requirement of water and gas combined atomization pulverizing under the atmospheric conditions, is suitable for small-batch production and product research and development.

2) Principle:

It works under the normal pressure environment, metal (alloy) material is melted by the induction heating furnace, after the material is melted and reaches atomization temperature, the operator pours the molten liquid metal into a heat preservation tundish, the liquid metal will pass through a guide pipe at the bottom of the tundish and form a liquid metal flow which enters an atomization chamber,, and will form a large number of fine metal droplets due to severe shock of water flow from an ultrahigh pressure nozzle (spray disc) and low pressure gas flow (the atomization process is more smooth accompanied by a jet effect under a water atomization nozzle) in the process, during the metal droplets flying and settling process, the metal droplets will be sphered under the action of surface tension and are quickly solidified (irregulated) due to water cooling action at the same time, the two processes are carried out at the same time, the final droplets morphology is the result of the above combined action, forming the sub-spherical or irregular particles, namely metal powder is formed.
The device belongs to a kind of gas protection atomization pulverizing equipment between water atomization and gas atomization.

3) Features:

1.Can produce a variety of most of the metal and its alloy powder, and the production cost is low;

2.Due to addition of a gas medium, the cooling speed of the droplets is reduced, the droplets are In much favor of sphering, so it can prepare sub-spherical powder or spherical powder with high apparent density.

3.The process is adjustable, and indicators such as powder granularity can meet the using requirements.

4) Composition:

It is composed of a medium frequency melting furnace, the heat preservation tundish, an atomization system, an ultrahigh pressure water system, an inert gas protection system, a powder collecting, dehydrating and drying system, a screening system, a cooling water system, a control system, a steel structure platform and so on.

5) Control:

The control system can be integrated into an operating table according to user requirements, and all operation and related data are transmitted to the PLC of the system to realize all the functions of operation, display, processing, storage, control and so on.
