1. Introduction to Electrical Steel

Electrical steel, also known as silicon steel, is a critical material in modern electrical engineering and construction applications. Its unique properties make it ideal for use in a variety of electrical devices, including transformers, electric motors, and generators. As we explore the properties of electrical steel, we will uncover how this material contributes to energy efficiency and operational effectiveness in the construction and decoration materials sector.

2. What is Electrical Steel?

Electrical steel is a type of specialty steel that is specifically engineered to have high magnetic permeability. This characteristic allows it to efficiently conduct magnetic fields, making it an essential component in electrical applications. The addition of silicon to the steel composition enhances its electrical properties while reducing energy losses due to hysteresis and eddy currents.
There are two primary classifications of electrical steel: **grain-oriented electrical steel (GOES)** and **non-grain-oriented electrical steel (NGOES)**. Grain-oriented steel is designed to optimize magnetic properties along a specific direction, while non-grain-oriented steel is more versatile, suitable for applications where magnetic orientation is less critical.
