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 […]

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, […]

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 […]
