Скачать или смотреть The whole feeding process for Plasma Rotating Electrode powder making equipment

Here are the steps involved in the feeding process for Plasma Rotating Electrode (PREP) powder making equipment:

The raw material is cut into rods of the desired length.
The rods are placed in the feed hopper.
The feed hopper is mounted on the rotating electrode.
The rotating electrode is heated by a plasma torch.
The molten metal is ejected from the end of the electrode by centrifugal force.
The molten metal is atomized by a stream of inert gas.
The atomized metal droplets are collected in a powder collection chamber.
The powder is then cooled and stored.
Here are some additional details about each step:

The raw material is typically a metal or alloy that is well-suited for powder metallurgy applications. Common materials include titanium, nickel, stainless steel, and refractory metals.
The rods are cut to a length that is appropriate for the size of the plasma torch and the desired powder size.
The feed hopper is mounted on the rotating electrode so that the rods can be fed into the plasma torch in a controlled manner.
The rotating electrode is heated by a plasma torch to a temperature that is high enough to melt the metal. The plasma torch is typically powered by a high-current, low-voltage source.
The molten metal is ejected from the end of the electrode by centrifugal force. The centrifugal force is created by the high-speed rotation of the electrode.
The molten metal is atomized by a stream of inert gas. The inert gas helps to prevent oxidation of the molten metal and to break it up into small droplets.
The atomized metal droplets are collected in a powder collection chamber. The powder collection chamber is typically made of a material that is compatible with the molten metal, such as stainless steel or graphite.
The powder is then cooled and stored. The powder is typically cooled in an air-circulating oven or a water bath. The powder is then stored in a sealed container to prevent oxidation.
The PREP process is a versatile and efficient method for producing high-quality metal powders. The process is well-suited for the production of a wide variety of metals and alloys, and it can be used to produce powders with a wide range of properties. The PREP process is also a relatively environmentally friendly process, as it does not require the use of hazardous chemicals.
