The aluminium scrap recycling process heavily relies on melting furnaces. When recycling aluminium, maintaining purity is essential to ensure that the reclaimed metal meets industry standards. Furnaces must be equipped to handle contaminated or coated scrap, often requiring pre-treatment stages like de-coating or salt fluxing to remove impurities. Advanced rotary furnaces and tilting reverberatory designs are particularly suited to these demanding applications due to their mixing capabilities and temperature uniformity.
