If you’re working with molten aluminum, degassing is a must. Why? Because hydrogen gas can sneak into the metal and cause porosity, which weakens the final product. That’s where a rotary degasser comes in handy. It works by spinning a shaft to mix inert gas into the melt, breaking it into tiny bubbles. These bubbles grab the hydrogen and carry it out—quickly and efficiently. Rotary degasser is ideally suited for large-scale foundries and applications requiring high-purity aluminum casting.
Despite its effectiveness, rotary degassing has some limitations, including higher equipment and maintenance costs, increased energy consumption, and the need for skilled operators to manage the process efficiently.
