Lamination Yokes for Induction Furnace – Technical Specification 1. Description
5. Cooling & Thermal Considerations
Lamination Yokes are magnetic core components used in induction furnaces to provide a low-reluctance path for magnetic flux generated by the induction coil. They enhance magnetic coupling, improve electrical efficiency, and reduce stray losses during furnace operation.
2. Function- Concentrates and guides magnetic flux around the induction coil
- Reduces magnetic leakage and stray field losses
- Improves furnace power efficiency and melting performance
- Minimizes heating of furnace shell and surrounding structures
- Enhances overall system stability
- Material: Cold Rolled Grain Oriented (CRGO) Silicon Steel Laminations
- Lamination Thickness: 0.23 mm / 0.27 mm / 0.30 mm
- Core Type: Step-lap or stacked lamination design
- Insulation Coating: Inorganic oxide coating (C5/C6 grade)
- Assembly: Bolted or clamped with non-magnetic stainless steel fixtures
- Shape: Curved or rectangular segments as per furnace coil design
- Mounting: External mounting around induction coil
Each lamination is insulated to minimize eddy current losses and improve magnetic efficiency.
