Electrical Steel
Applications
Electrical steel is used in various electrical applications due to its magnetic properties. Its main uses include:
• Transformer Cores: Efficiently direct magnetic flux, reducing energy loss. The main parts of electrical transformers are transformer cores. Their main job is to make it easier for magnetic induction to efficiently transmit electrical energy from one circuit to another. The transformer's primary winding generates magnetic flux, which the core focuses and directs onto the secondary winding to transform voltage. This makes it possible to distribute electricity at various voltage levels, which is necessary for power transmission and distribution.

1. Cold Rolled Grain Oriented Electrical Steel (CRGO)
CRGO is a specialized variant of electrical steel with anisotropic magnetic properties. The manufacturing process for this type involves careful control of crystal orientation. Sheets are rolled in a manner that aligns the crystal grains predominantly in one specific direction relative to the sheet, creating a preferred direction for maximum magnetic permeability. CRGO plays a pivotal role in the fabrication of energy-efficient transformers and high-performance generators. Its characteristics include low power loss per cycle, low core loss, and high permeability, all optimized for a distinct magnetization orientation. Because of its crystal orientation, CRGO, which enhances magnetic permeability in one direction, is perfect for transformers. The magnetic field direction of rotating machinery, which necessitates materials with isotropic magnetic properties, continually varies. Therefore, this anisotropic attribute isn't appropriate.
2. Cold Rolled Non-Grain Oriented Electrical Steel (CRNGO)
CRNGO is distinguished by its isotropic magnetic behavior, or the fact that its magnetic properties are constant in all directions. During the manufacturing process, the molten CRNGO steel is cast into thin sheets without special processing to deliberately produce a particular alignment of the crystal lattices within the grains. This lack of a preferred crystal orientation results in the steel's uniform magnetic behavior. CRNGO is suitable for applications requiring consistent performance in all directions. CRNGO finds its primary use as core parts in electrical motors and generators. Using CRNGO in rotating machinery is sensible because it maintains consistent magnetic properties in all directions, optimizing energy efficiency. Unlike Cold Rolled Grain Oriented Steel, CRNGO adapts well to the changing magnetic field directions in motors and generators, reducing energy loss. Its noteworthy properties include high permeability, low core loss, and cost-effectiveness, making it a practical choice for applications where isotropic magnetic behavior is advantageous.
