Induction Furnace Transformer: Why It Matters in a Complete Melting System
The furnace transformer is an important part of a complete induction melting system.
It provides the electrical interface between the plant power system and the medium frequency power supply.
Transformer and power supply
The basic electrical architecture is:
Plant power → furnace transformer → medium frequency power supply → capacitor → induction coil
Each stage must be matched to the next.
Transformer selection
Important factors include:
- Input voltage
- Output voltage
- Rated power
- Frequency
- Furnace capacity
- Power supply configuration
- Electrical installation requirements
Large furnace systems
As furnace capacity increases, the electrical system becomes more demanding.
Large furnaces such as 20-ton, 30-ton and 40-ton systems require carefully engineered transformers and power supplies.
Customized design
Induction furnace transformer requirements vary between projects.
The transformer should therefore be selected according to the actual power supply and furnace configuration rather than using a generic transformer specification.
Complete engineering
A transformer supplier should understand the complete induction furnace electrical system.
This allows the transformer, power supply, capacitor bank and induction coil to be properly coordinated.
Conclusion
The induction furnace transformer is an important link between the electrical grid and the melting furnace.
For a complete project, transformer selection should be performed as part of the overall electrical engineering process.
