On the Effectiveness of Rotary Degassing of Recycled Al-Si Alloy Melts: The Effect on Melt Quality and Energy Consumption for Melt Preparation

The effectiveness of rotary degassing on the defect formation and mechanical properties final casting aluminium alloy EN AC 46000 was investigated, along with its impact energy consumption in furnace. In melt preparation prior to casting, molten metal is usually transported from melting furnace as a cleaning procedure. Under conditions this specific study, negligible degradation observed cast component an after removing step process. Furthermore, led reduced temperature drop melt, thus minimizing need for reheating (energy consumption) by up 75% 124,000 kWh yearly production 1500 kg environmental showed ~1500 reduction CO2 one electrical year.
