Pole sheet electrical steels Product Description
Hot and cold rolled pole sheet grades are classified according to their yield strength (EN 10265:1995). As well as guaranteed mechanical properties, they have guaranteed magnetic properties, but unlike other electrical steel grades, their magnetic characterisation is determined under direct current (DC) conditions.
Pole sheet electrical steels Advantages
- Allow cold rolled grades to withstand strong electromechanical forces
- Allow hot rolled grades to withstand strong centrifugal and electromechanical forces, both in static and dynamic conditions
- Excellent DC magnetic properties of both grades
Manufacturing Process:
The manufacturing of pole sheet electrical steels usually involves multiple complex processes, including steelmaking, hot rolling, cold rolling, annealing, and coating. For instance, ultra-thin pole sheet electrical steels need to rely on advanced rolling processes to be accurately rolled into extremely thin thicknesses. During the manufacturing process, precise control of the material's composition and microstructure is also required to ensure it has excellent magnetic and mechanical properties.
Pole sheet electrical steels Application
Power Industry: Pole sheet electrical steels are core materials for manufacturing power equipment such as transformers, reactors, and inductors. In high-frequency transformers, ultra-thin pole sheet electrical steel strips can effectively reduce core loss, improve the efficiency and power density of transformers, and are suitable for high-frequency power transformers in fields like aerospace, communications, and electronics.
Electronic Information Industry: In electronic transformers such as power adapters and chargers for electronic products like mobile phones, computers, and tablets, pole sheet electrical steels can meet the requirements of miniaturization and high efficiency, improving the performance and battery life of electronic devices. Additionally, in high-frequency motors used in fields such as drones and humanoid robots, the use of pole sheet electrical steels can also reduce the eddy current loss of the motor and enhance its efficiency and power density.
New Energy Field: In solar photovoltaic power generation systems, pole sheet electrical steels can be used to manufacture components such as transformers and reactors in photovoltaic inverters, improving the conversion efficiency and stability of the inverters. In wind turbine generators, pole sheet electrical steels can meet the requirements of high magnetic induction and low loss for equipment like generators and transformers, enhancing power generation efficiency and equipment reliability.
Medical Equipment Industry: In high-frequency medical X-ray machine power supplies, pole sheet electrical steels can be used to manufacture components such as transformers and reactors, providing stable high-frequency and high-voltage power supplies to ensure the normal operation and imaging quality of X-ray machines. In the modulator power supplies of linear accelerators, pole sheet electrical steels can also be used to manufacture key components, ensuring the high precision and high stability of the equipment.
