摘要：

The introduction of static frequency converters in the 1980's led to a new impetus for inductive melting. Mediumfrequency (MF) crucible furnaces have since then become established as standard melting systems, particularly in iron foundries [1]. The higher, adaptable frequency of the coil current enables crucible furnaces fed by converters to be operated in batch type mode at a much higher power density and without any loss of melting performance, even if the furnace is emptied completely each time. Apart from economic gains and process benefits, a particular advantage is that energy efficiency can be increased compared to crucible furnaces operated at line frequency. After a brief characterization of MF inductive melting technology, this paper goes on to describe how this increase can be optimized by means of action concerning the processes and the system itself. © copyright: DIV Deutscher Industrieverlag GmbH / Vulkan-Verlag GmbH -02/2016.
