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, […]
