The Faraday Ring is a conductive shielding component installed at the top and/or bottom of a coreless induction furnace coil. It is designed to control stray electromagnetic fields, minimize induced currents in surrounding metallic structures, and protect the furnace shell from overheating and electrical damage.
2. Function- Acts as an electromagnetic shield to contain leakage flux
- Reduces stray eddy currents in furnace structure and shell
- Prevents overheating of metallic components
- Enhances electrical efficiency of the induction system
- Improves operational safety and reduces electromagnetic interference
- Material: High Conductivity Copper (Electrolytic Grade)
- Type: Solid ring or segmented (multi-piece) design
- Cooling: Water-cooled (hollow copper sections with internal channels)
- Surface Finish: Polished or anti-oxidation coated
- Joints: Brazed or welded for leak-proof construction
The ring is designed to handle high induced currents and thermal loads during furnace operation.
