Rotary Degassing Unit is used to complete degassing operation. Inert gas is introduced to produce efficient small bubbles. Short processing time and reduced gas use can save a lot of cost. The degassing treatment of the melt causes the injector immersed in the melt to rotate so that the scavenging gas (usually inert gas) is […]

Aluminum Liquid Purification is important, because the electrolytic aluminum solution contains a large number of non-metallic inclusions and carbides, nitrides, and sulfides. When the electrolytic aluminum liquid directly enters the melting pool of the smelting furnace, it is easy to adhere to the refractory lining of the smelting furnace, and is closely integrated with the […]

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 […]

Rotary degassing equipment is an advanced melt purification method. The purification effect is good and does not pollute the environment. The purified melt can enter the casting machine or rolling mill directly without secondary pollution, which improves the production efficiency. The purity of molten aluminum directly affects the processing quality of aluminum, so crude aluminum is […]

Aluminium Degassing Process: In addition to hydrogen, it is necessary to prevent moisture and various dirt from entering the crucible or furnace, but also to eliminate oxide inclusions and hydrogen in the aluminum liquid. Because only by effectively removing the dispersed inclusions suspended in the molten aluminum, can the molten aluminum be prevented from increasing […]

Degassing Aluminum with Nitrogen: Nitrogen enters the bottom of the aluminum liquid through a certain process device. The nitrogen floats up from the bottom of the aluminum liquid in the form of bubbles. Due to the hydrogen partial pressure difference at the contact interface between the bubble and the molten aluminum, the partial pressure of […]

Rotary Degassing Aluminum works by rotating nozzle of degassing unit. The rotating nozzle has a rotating shaft, a rotor with blades (connected to the rotating shaft), and a stator with blades. Their interaction can provide the desired bubble shape for the melt. The refined gas emerges into the aluminum melt through the small gap between […]

After the adjustment of the molten metal composition is completed, the next step is the refining process of molten aluminum. The purpose of aluminum alloy refining is to obtain high cleanliness and low gas content alloy liquid after taking degassing and impurity removal measures. There are several methods for refining: Add chloride (ZnCl2, MnCl2, AlCl3, […]

Aluminum is the most abundant metal element in the earth’s crust. The density of aluminum is very small, only 2.7 g / cm, and it is malleable. It can form an oxide film to prevent metal corrosion in humid air. Aluminum can be made into a variety of shapes: rod, sheet, foil, powder, ribbon, and […]
