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 […]

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, […]
