Development of an Online Aluminum Melt Degassing and Purification Box
Release Time:
2025-05-30
The purification effect of aluminum alloy molten metal during the casting process directly affects the quality of its products. Therefore, preventing and reducing the hydrogen content and solid non-metallic inclusions in the ingots has become an important process in the production of smelted ingots.
The development of an online degassing purification box for molten aluminum is an important topic in the aluminum processing industry. This box aims to effectively remove gases and impurities from molten aluminum through specific processes, thereby improving the quality and performance of aluminum materials.
During the development process, researchers conducted in-depth studies on the degassing principle. They used the gas flotation principle by injecting process gases (such as inert gases or a mixture of inert gases and chlorine) into the molten aluminum. The gas is broken into tiny bubbles within the aluminum. These bubbles, as they rise, can adsorb and carry away hydrogen from the aluminum, react with chlorine to remove alkali metal impurities, and capture inclusions to bring them to the melt surface to form slag.
To ensure the degassing effect, the box design pays attention to details. For example, it is equipped with a precise heating system to control the temperature of the aluminum; the rotor structure is optimized to improve gas dispersion efficiency and prevent clogging; the selection of sealing materials is also strictly screened to ensure the airtightness of the box.
In addition, the box is easy to operate and maintain. Operators only need to follow established procedures to achieve a stable degassing working state.
In summary, the development of the online degassing purification box for molten aluminum is an important technological innovation achievement in the aluminum processing industry. It not only improves the quality of aluminum materials but also brings significant economic benefits to aluminum processing enterprises. With continuous technological advancement, it is believed that more efficient and intelligent degassing purification equipment will emerge in the future, injecting new vitality into the development of the aluminum processing industry.
