Engineering 2017, Volume 3, Issue 3,   Pages 423-427 doi: 10.1016/J.ENG.2017.03.006

Abstract:

The present work explores the application of microwave heating for the melting of powdered tin.Microwave penetration was found to have good volumetric heating on powdered tin.Conduction losses were the main loss mechanisms for powdered tin by microwave heating at temperaturesThe results suggest that microwave heating accelerates the heating rate and shortens the melting timeThus, the microwave melting process improved heating efficiency and reduced energy consumption.
