Best ROI for Your Furnace
In the world of aluminum production, achieving optimal energy efficiency and minimizing metal loss isn’t just about cost savings; it’s a critical step towards a greener future. If you’re looking to improve your bottom line and your environmental impact, optimizing your reverberatory aluminum melting furnace is a key strategy. Let’s explore how to maximize your ROI while supporting a more sustainable aluminum industry.
Understanding Rotary Degassing of Aluminum
Rotary degassing is a critical process in aluminum casting to remove dissolved hydrogen and impurities from molten aluminum. Dissolved hydrogen, if left unchecked, forms bubbles during solidification, leading to porosity in the final casting. This porosity negatively affects mechanical properties, reducing strength and ductility.
Low Air Flow Freezes Pumps!
The primary reason for molten metal pump freezing is "slow starts." A slow-start is defined as slowly increasing the motor RPM. When a transfer pump is slow-started, the hot metal flows gradually into a cooler riser. As the metal temperature decreases, it solidifies or freezes inside the riser. This slow-start condition typically results in permanent damage and the need to rebuild the pump or at the very least replace the riser.
