Impactof Rotor Design on Its Wear and Work Efficiency ofthe Aluminum Refining Process

Original language description

Both the wear and the geometry of the rotor determine the efficiency of the processof aluminum refining. The paper presents wear tests of two different rotors: I (pump type) and II (pro-peller type). The operation of both rotors in industrial conditions was compared and their service life was examined.It was found that rotor I is more durable than the tested rotor II, and at the same time it provides a good level of hydrogen removal throughout the operation period, i.e.,1112 refin-ing cycles. Rotor wear after refining was calculated by 3D scanning. The study also investigated the impact of rotor geometry on the efficiency of the refining process. The degassing efficiency was determined during refining in a foundry using the Dichte Index (DI). The alloy density and the volume of hydrogen removed were also tested for five stages of rotor wear: 0%, 25%, 50%, 75% and 100%. Both new rotors performed worse in removing hydrogen from the liquid alloy than the worn rotors due totheir humidity which cannot be eliminated in the initial stage of their operation. A Dross Test was also performed to determine non-metallic impuritiesand comparesize and number of cavities for rotor I and II.The best results of removing non-metallic inclusions by flotation were obtained for rotorIat the end of its operation.
