When recyclingRecycling contaminated aluminium scrapAluminium scrap, recyclers face the challenge of low-density scrapScrap and volatile surface contaminants degassing from the surface of the scrapScrap. To overcome this, the two-chamber furnace is used to minimize dross formation and utilize the volatiles in the process to heat the scrapScrap. Since the two chambers, hot and cold, have limited natural convection of liquid aluminiumAluminium, using a device to transport the aluminiumAluminium from the hot to the cold chamber is common practice. This device can be an electromagnetic stirrer (EMS) or a pump. The amount of heat that the device transports is proportional to the amount of liquid that is moved, and a higher velocityVelocity will better penetrate the meltingMelting scrapScrap in the cold chamber. This paper will compare the amount of volume flowVolume flow and the circulationCirculation patterns created by EMS and pumping devices in a typical two-chamber furnace. The results will show that EMS can increase the meltingMelting rate, decrease the time required to homogenize temperature in both chambers, and enable final composition to be achieved in a shorter time/(reduce alloy dissolutionDissolution time) compared to pumps.
