Aluminium alloys need to meet ever more stringent quality requirements, particularly for beverage cans, foils, fine wires, lithographic sheets and bright trims. In fact, inclusions lead to problems when metal is produced to ever decreasing thicknesses approaching those of the inclusion size or when surface quality is paramount.
The DBF / Deep Bed Filter® consists of an insulated box containing layers of carefully sized alumina balls through which molten aluminium flows from top to bottom. The filtering area, or bed, is sized as a function of metal flow rates.
