| Abstract Scope |
Processing aluminum scrap with surface contaminants poses challenges due to its low density and the release of volatiles during melting. A two-chamber furnace design addresses these issues by limiting dross formation and utilizing the energy from volatiles to assist in heating. Natural convection between the hot and cold chambers is minimal, therefore active circulation of molten aluminum is necessary. This is typically achieved using either a pump or an electromagnetic stirrer (EMS). The effectiveness of each method depends on the volume and speed of liquid transfer, which influence heat distribution and melting efficiency. This study compares the flow behavior and circulation patterns generated by these two technologies. Results will demonstrate that EMS enhances melting rates, accelerates thermal homogenization, and reduces the time required to reach the desired alloy composition more effectively than conventional pumping systems. |
