Rendered degaussing coil type RE and power module DN1100.
  • The special coil module generates extremely high field strengths in continuous operation
  • Optimized to demagnetize bars and tubes
  • The demagnetizing frequency is adjusted in the factory to the expected wall thicknesses of the parts and to the conveying speed
  • The coil module generates a high magnetic field strength even at a higher demagnetizing frequency
  • A high demagnetization performance is achieved from the forced coil cooling at 100% switch-on time
  • Field strengths exceeding 190 kA/m are reached using pulse demagnetizing
  • The coil is housed in a rugged cast metal enclosure, which largely shields the stray fields

Maurer Magnetic

Magnetically pure

Series RE demagnetizers combine new technologies and a rugged design with maximum performance and cost-effectiveness. As compared to conventional continuous flow systems, which typically reach a field strength of 10 – 30 kA/m, the RE demagnetizing coils reach values of 60 – 90 kA/m. This corresponds to up to 10 times higher performance. Coils designed for continuous operation are especially well suited to efficiently demagnetize large volumes of rods or tubing material. Furthermore, the Maurer Degaussing® power modules also allow a pulse demagnetization capable of reaching field strengths that exceed 190 kA/m. Materials of different diameters can be successfully demagnetized without having to adjust process parameters and without any performance loss.

Integration into automated production systems is extremely easy thanks to the standard control interfaces.

In 2001, Maurer Magnetic developed the Maurer Degaussing® demagnetizing process, for which a patent was applied for. With our many years of experience and the expertise we have acquired over time, our technology has been continuously enhanced, while our new relevant patents supplement it. Our in-house production also allows us to implement customer demands quickly and unimpeded, while ensuring our quality standards at the same time.

Applications

Powerful coils for hard industrial applications

Demagnetization of a bar with constant speed by means of the demagnetizer type RE. Continuous demagnetization enables constant production with constant quality.
The material is transported at a constant speed through the coil during demagnetization. The demagnetizing process is the result of a continuous material flow through the coil.
Demagnetizing coil type RE with a rod, almost the same diameter as the coil opening of the demagnetizing coil RE. The demagnetization is still very reliable and productive even at the highest filling level.
Efficiently and consistently demagnetizes with an up to 90% degree of filling.
Rendered product portfolio of various rods and tube profiles. Reinforcing bars, L-profiles or various square profiles can be efficiently demagnetized with the demagnetizer RE.
Especially suited to demagnetize rods, tubes, profiles and even individual parts. The demagnetization process at the end of the rod is terminated with a decreased Maurer Degaussing® pulse.

Suitable for high material throughput and solid material

The RE coil modules allow rods or tubes to be demagnetized with throughput speeds of up to 3 m/s. Thanks to forced air cooling directly inside the coil, very high magnetic field strengths can be generated without directly overheating.

When stopping production while material still remains in the coil, the stepped shut-down sequence coming from the Maurer Degaussing® process must be activated to prevent very rapid, overheating of the material. This has to be done manually or via the integrated interface.

What demagnetizing with RE + DN means for you:

  • The ability to meet the customer’s residual magnetism limits
  • Demagnetize larger material quantities (rods and continuous material)

Range of parts

  • Semi-finished products in large quantities
  • Components after a crack test (alternating and direct current crack testing)
  • Continuous production of rods and tubes
