Narrow Customized Electric Silicon Steel Coil Product Description

A narrow electric silicon steel coil is a thin, high-grade electrical steel strip with low carbon content, enhanced with silicon to improve its magnetic properties, such as high permeability and low iron loss. These properties are achieved through precise alloying and processing to create laminations for transformers, motors, and generators, with narrow-width coils being a common product form.
Electric Silicon Steel Coil Key Characteristics and Properties
Composition:
A soft magnetic alloy of iron and silicon, with silicon content typically between 0.5% and 4.5%.
Improved Magnetic Properties:
Silicon addition increases the resistivity, permeability, and magnetic induction of the iron, while reducing coercivity and hysteresis loss.
Energy Efficiency:
Low iron loss and high permeability make these coils ideal for power equipment, reducing energy consumption and improving efficiency.
Manufacturing Process:
Produced as cold-rolled strips, which are then cut into laminations for assembling electrical cores.
Grain Structure:
The grain structure can be controlled through heat treatment to optimize magnetic performance.
Types of Silicon Steel Coils
- Oriented Silicon Steel (CRGO):
Has optimal magnetic properties in the direction of rolling, making it suitable for large transformers.
- Non-Oriented Silicon Steel (CRNGO):
Exhibits similar magnetic properties in all directions and is commonly used for motors and generators.
Electric Silicon Steel Coil Applications
- Transformer cores: The laminations are stacked to form the cores of electrical transformers.
- Stators and rotors: Used in the construction of electric motors.
- Generators: Employed in the manufacturing of power generators.
- Precision machinery: Also used in other precision mechanical and electrical devices.
