Electromagnetic caster stirrer designs vary depending on use

Home / Powering Your Process / Electromagnetic caster stirrer designs vary depending on use

Electromagnetic stirrers for steel applications produce very low frequency, high amplitude magnetic fields to agitate steel when molten. Steel applications include ladle stirring and stirring in continuous cast steel for alloy integrity. Always under water during operation, cooling water wicks the heat away from these induction coil sets.

Depending on how the stirrer is used and the effects desired, caster stirrer design options begin with some of these basic differences.

Stater or Core Assembly design options:

  • Removable from the outer casing weldment
  • Permanently attached to the interior of the casing weldment

Conductor/Magnet wire options include:

  • Flat shaped conductor with both polyester and KaptonTM dielectric insulation coatings
  • Round shaped conductor with a Kapton dielectric insulation coating

When caster stirrers come through the shop, we conduct several electrical tests to establish a baseline for each individual caster stirrer before we begin disassembly. Conducting these tests helps us in our quest to determine the root cause of failure. We document the disassembly and share details and findings with our customers.

I cover this in more detail in a video. Watch here in our Video Gallery or on YouTube.
