Silicon steel sheet: key material in electromagnetic applications

 

Silicon steel sheet is an alloy material with silicon and iron as the main components, which has important applications in the electromagnetic field. Due to its excellent magnetic conductivity and low energy loss, silicon steel sheet is widely used in the core components of transformers, motors and generators.

Classification and characteristics of silicon steel sheet

Silicon steel sheet is mainly divided into two types: hot-rolled silicon steel and cold-rolled silicon steel.
– Hot-rolled silicon steel: The production process is simple and the cost is low, but the surface is rough and the thickness control accuracy is low, which is usually used in low-end applications.
– Cold-rolled silicon steel: It has high surface quality, good ductility and precise thickness control, and is widely used in high-performance equipment.

Cold-rolled silicon steel can also be divided into oriented silicon steel and non-oriented silicon steel according to silicon content and directionality:
– Oriented silicon steel: The magnetic permeability is optimized in one direction, which is suitable for equipment such as transformers that require oriented magnetic fields.
– Non-oriented silicon steel: It has uniform magnetic properties in all directions and is commonly used in motors and generators.

Silicon steel sheets are the preferred material for transformer cores due to their excellent magnetic conductivity and low eddy current losses. The increase in silicon content can significantly improve the material’s anti-magnetization ability while reducing energy loss. In addition, its high strength and fatigue resistance meet the needs of motors and generators for efficient and durable materials.

3 PHASE (3UI) LAMINATION CORES

图片
3UI lamination cores are used in the manufacturing of three-phase transformers. In transformers with 3 UI lamination cores, each of the three ei lamination core arms bears a coil body. In contrast to the EI sheets, the 3UI sheets cannot be welded since the joints of the E and I sheets are within the coil body. The E and I sheets therefore have to be nested reciprocally during transformer manufacturing. As a result, either one or multiple identical sheets are slid in from one side of the coil body. Nesting machines are available for the nesting of 3UI sheets, which can significantly reduce manufacturing times. (source:https://www.ei-lamination.com/3-phase-3ui-lamination-cores/)

Interpretation of laminated steel core transformer

图片
  Laminated steel core transformer is a new type of power transformer. It is becoming more and more popular due to its compact structure, remarkable effect and light weight. Laminated steel core transformers add multiple layers of insulating materials to the steel core to improve current transmission efficiency, avoid core AC losses, and reduce noise and vibration. It can also improve the reliability and safety performance of the transformer. The advantages of laminated steel core transformers lie not only in their service life, reliability and efficiency, but also in their environmental protection. They are made of non-toxic, odorless and recyclable materials and have no negative impact on the environment and human body. However, laminated steel core transformers are not suitable for all applications. In terms of application, factors such as the rated capacity of the transformer, operating environment, output voltage, etc. need to be considered to ensure ...
