Not at full capacity? You can still melt efficiently
Once operational again, many aluminium foundries are likely to face periods of unpredictable production and interrupted melting. As well as increasing energy consumption, this stop/start process can also result in metal quality decreasing due to oxidation and dross formation.
This doesn’t have to be the case. Switching to longer melting periods during low utilization, where melting and holding are automatically applied in the most energy efficient way, can prevent energy wastage and ensure quality isn’t compromised. This is especially the case when melting furnaces are operating below 75% capacity.
