Clutch plates in the transmissions of wind turbines transmit high levels of torque. The martensite grades produced by Waelzholz for this purpose exhibit excellent resilience combined with outstanding flatness. Piece hardening, which has a negative impact on the flatness of steel for hardening and tempering, is not needed with Martensite.
HP- and CWD-PERM® grades are the right choice for the stator laminations used in electric motors with higher torque. This electrical steel strip features outstanding polarization values, ensuring excellent magnetizability. In addition, excellent thermal conductivity ensures that operating heat is dissipated extremely effectively.
Our steels for hardening and tempering are characterized by exceptional formability and a high carbon content. This makes them easy to transform into plates and bushes for bicycle chains, and subsequent thermal treatment makes them extremely robust and durable.
Generators require powerful lamination stacks with a magnetic flux that is as undisturbed as possible. We achieve this using bonding varnish technology, which bonds lamination stacks without disturbing the magnetic flux. What’s more, there’s no frequency hum which occurs with other bonding methods.
The energy revolution is having a massive impact on the field of energy generation. Climate change and volatile energy prices are creating a highly dynamic market for renewable energy concepts. The energy supply is becoming more fragmented and decentralized – increasing the demand for efficient transformers and high-performance generators. These, in turn, require electrical steel strip with low core losses, high flux density, or permeability. Our expertise lies in supplying electrical steel strip with magnetic properties precisely tailored to the respective application. Outstanding reliability is an important aspect in this context – after all, transformers or generators normally run 24 hours a day, 7 days a week, 365 days a year. Our high-quality materials with consistently defined properties across numerous production batches play a key role in guaranteeing a reliable energy supply.
