High Frequency Induction Tube Furnace for Determination of Ash Melting Temperature

Abstract

The article describes the designed and manufactured tube furnace intended for, inter alia, determining the melting temperature of ash conforming to the standard of ISO-540:2001. The possibility of digital sample observation and several programs controlling the obtainable temperature enable to determine the test cycle in any case (convenient for the researcher). Reduction of testing time allows for the analysis of the observed phenomena, as well as more detailed research plan of samples, where substantial changes have been demonstrated.
