• Features of Induction Melting Furnace
• Heat Balance of Induction Furnace
• Energy Saving Measures for Induction Furnace
• Conclusion

3
Objective

• To know the features of induction furnace, heat
  balance compared with low-frequency induction
  furnace and high-frequency induction furnace, and
  energy saving measures.

4
Features of Induction Melting Furnace

• Heat efficiency is high.
• No CO2, Little smoke soot.
• Little oxidation/contamination.
• Temperature control is simple.
• Installation space is reduced.

5
Heat Balance of Induction Furnace

• Total Efficiency

6
Energy Saving Measures for Induction Furnace

• Improved Heat Efficiency by Improvement of
  Furnace
• Improvement of Heat Efficiency in Operation
• Preheating of Material

7
Improved Heat Efficiency by Improvement of Furnace

• Equipment Layout
• Frequency

8
Improvement of Heat Efficiency in Operation

• Furnace cover should be closed as far as
  possible.
• Molten metal should be held at low temperature
  and in short time.
• Dust collecting hood.
• Cleaning of sand, rust and other dirts.

9
Conclusion

• Many features have induction melting furnace.
• Total efficiency of high-frequency induction
  furnace is more preferable than low-frequency
  induction furnace.
• You must try to improve heat efficiency in
  operation carefully.
