The online rotary degassing machine is used for on-line degassing and slag removal outside the furnace of the aluminum melt. The hydrogen content in the aluminum melt after the on-line degassing device meets the requirements of the casting process. Working Principle of Rotary Degassing Machine A certain flow of inert gas is injected into the […]

The molten aluminum degassing equipment adopts compact furnace design. In the degassing box, a rotating nozzle is used to degass the molten aluminum, and convection is formed in the box so that small bubbles can completely diffuse into the molten aluminum. At the same time, the sealing design is adopted to prevent the secondary pollution […]

Degassing With Inert Gas is widely used in the metal casting process. The melt and dissolved hydrogen do not react with chemical reactions and do not dissolve in aluminum, such as nitrogen and argon, usually using nitrogen. When the inert gas is blown into the melt, many fine bubbles are formed. When the bubbles pass […]

Degassing process in aluminum can be divided into two situations: one is the hydrogen removal process that can form hydrogen bubbles; the other is the hydrogen removal process that cannot form hydrogen bubbles. The degassing process in aluminum that can form hydrogen bubbles can be roughly divided into three stages: first, the formation of bubbles, […]

Aluminium degassing machine most notable feature is the graphite stator and graphite rod/rotor structure. The graphite stator does not rotate in the molten aluminum and protects the graphite rod/rotor assembly. The graphite rod and the graphite rotor are assembled together to stir the aluminum water. The inert gas passes through the gap between the stator […]

In order to improve the purification treatment effect for continuous casting and ensure the stable and reliable melt quality, the molten aluminum adopts a combination of continuous purification treatment inside and outside the furnace. Purification Treatment for Continuous Casting The main function of the on-line refining treatment device outside the furnace is to refine crystal […]

Aluminum Refining Flux should be added in proportion. The aluminum refining agent is generally 0.3% of aluminum alloy. Method Use a seamless steel pipe inserted 20cm from the bottom of the molten aluminum, and spray the refining agent with nitrogen or argon. After the refining spray, the nitrogen or argon is blown for another 15-20 […]

AdTech offers Rotary Degasser and flux for molten aluminum degassing. In the rotary degassing method, inert or chemically inert gases (argon, nitrogen) are removed through the rotating shaft and rotor. The energy of the rotating shaft leads to the formation of a large number of fine bubbles, thus providing a very high surface area to […]

When the hydrogen content in the aluminum casting reaches a certain value, its mechanical properties will be seriously reduced. And hydrogen embrittlement will occur, causing the casting to be scrapped. In order to prevent cracking defects caused by hydrogen in the alloy, AdTech offers molten aluminum refining degassing system to remove hydrogen from the aluminium […]
