1. Device Application
The intermediate frequency furnace for atomization and milling is melted in a vacuum or metal alloy. Under high pressure gas, the molten metal liquid is then diverted from the mouth (downward) through the insulating crucible, and the metal liquid will be atomized and passed through the nozzle through high pressure air. Breaking into droplets of many fine droplets, the droplets will solidify into non-spherical or spherical particles in flight to achieve the purpose of the flour.
This product belongs to a new type of professional furnace, introduced and designed and manufactured by foreign technology, and has the international advanced level. The unique hydraulic tilting linkage mechanism can always pour the metal solution into the small diameter receiving port during the whole process of melting the molten metal. It is a equipment that produces metal powder and similar processes using a water ( gas ) atomization process.
2 , introduction:
The medium frequency frequency furnace for atomization and milling uses induction energy for energy-saving medium frequency power supply. 30KW -2500KW , mainly used for remelting and alloying of iron-based alloys, and also for smelting, heating, quenching and atomizing and milling of nickel-based, copper-based raw materials and non-ferrous metals such as aluminum, gold and silver. The capacity of this series of products is small, generally 30Kg - 1000 Kg . In the process of pouring, the molten metal is always poured into the gate through the spout, the spout has no back and forth movement, and the precision of the fixed point casting is high. Pouring does not require tundish, the nozzle is very short, and the medium temperature is lowered during the casting process, so it is widely used in places where the fixed point pouring operation is required, such as powder metallurgy water (gas) atomization copper powder, iron powder, stainless steel. Powder and so on.

What are the main production costs of atomized metal powder?
The main cost is electricity, followed by gas (if it is aerosolization), water (if it is water atomization)
Water atomizing method milling process for preparation of metal powder:
First, the metal or alloy is melted and refined in the induction furnace, and the molten metal liquid is poured into the heat preservation crucible. During the flow of the metal liquid along the guide tube, the ultra-high pressure water flows through the nozzle to break the metal liquid into a large number of fine metal droplets, and is small. The droplets form sub-spherical or irregular shaped particles under the action of surface tension and rapid cooling of water during flight. The atomized metal particles are solidified, settled in the atomization tower, and finally fall into the powder collecting tank. Collect and separate. Moreover, by adjusting different parameters in the milling process, metal powders of various particle size distributions and morphologies can be obtained, thereby better satisfying mechanical manufacturing, automobile industry, aerospace and metal injection molding, friction materials, oil-impregnated bearings, A wide range of requirements in the field of powder metallurgy, such as structural parts and diamond tools.
