The available energy saving approaches in induction melting operations are
twofold:
• Reduction of the furnace system\'s electrical losses through improved
design
• Use of optimized operating and control regimes
The first part of this paper describes in quantitative terms, based on a
review of investigations and test results, how the surplus consumption of
power can be reduced markedly through proper feedstock selection, correct
charging techniques and an optimum adjustment of furnace parameters.
Furnace design has been improved with the aim of addressing the largest
loss factor, i.e., electrical losses in the induction coil, in an effort to cut these
losses substantially.
It was demonstrated that the new design yielded energy savings in the
range of 5 to 10 %.
