Alüminyum Hidrojen

The rotary degasser breaks up the Nitrogen large bubble into a very fine small bubble by rotating the Nitrogen rotor at a high speed and uniformly disperses it in the molten metal.
By reducing the diameter of the bubbles, the total surface area of these bubbles increases sharply, which causes more Nitrogen bubble surfaces to come into contact with hydrogen and impurities in the molten metal to bring these harmful substances to the surface of the liquid.

Gazın giderilmesinin anahtarı döner gaz giderici is that the rotor can break up the incoming Nitrogen bubbles into small bubbles and spread them throughout the molten metal. By reducing the bubble diameter, the surface area of Nitrogen is drastically increased, so that more Nitrogen surface contacts hydrogen and impurities in the molten metal and removes Aluminum Hydrogen or impurities from the aluminum liquid as the bubbles rise.

The flow control into the aluminum Nitrogen can adjust the flow rate of the gas according to the volume of the metal liquid being treated, and the speed of the rotating rod and the rotor can be adjusted to produce a bubble of an appropriate size to facilitate the diffusion of the inert gas.

Both argon and nitrogen can be used as an inert gas to degas the molten aluminum. The purity of the inert gas must be above 99.99%.

Degassing is the purpose of spraying Nitrogen into molten aluminum to remove hydrogen.
Buna ek olarak, gaz giderme işleminin de safsızlıkları yüzeye çıkarmak için oldukça etkili bir yöntem olduğu kabul edilmektedir.
Two main theoretical modes have been proposed to explain the principle of degassing. The macro mode considers that the removal of each impurity is similar in nature. The microscopic mode, that is, according to this theory, due to the higher vapor pressure of Aluminum Hydrogen, the dissolved hydrogen diffuses into the gas in the injected aluminum liquid.
Theoretically, an inclusion having a diameter of 10 microns contacts a bubble and is adsorbed on the bubble and floats up to the surface of the liquid.

AdTech is an enterprise specialized in new material development and high precision online degassing unit production since 2012, got positive feedback from domestic and overseas market.

Çevrimiçi gaz giderme ünitesi, uzun bir hizmet ömrü sağlamak için gelişmiş yüksek silikon eritme teknolojisini kullanır; gaz giderme rotoru, ısıtıcı koruma kılıfı ve termokupl koruma kılıfı ise yüksek hassasiyetli alüminyum üretimi gereksinimlerini karşılayabilen seramik üretim teknolojisiyle üretilmiştir.

Fırın ile döküm ekipmanı arasına çevrimiçi gaz giderme ünitesi kurulmalıdır. Bu ünite, erimiş alüminyumdan hidrojen (H) ve cürufların uzaklaştırılması için kullanılır. Çevrimiçi gaz giderme ünitesi, işleme ve ısıtma olmak üzere iki işlevi yerine getirir. Yüksek hassasiyetli erimiş alüminyum arıtma endüstrisine hizmet eder.

Esas olarak erimiş alüminyumdan hidrojen (H) ve cürufların uzaklaştırılması için kullanılır.

It takes gas flotation principle. The rotor takes inert gas or mixture of chlorine and inert gas into molten aluminum and smash the gas into dispersed tiny bubbles, the bubbles rise to molten aluminum surface and finish the below stated procedures at the same time.
