CRNGO silicon steel possesses several key features such as:
1. Non Grain Oriented Structure
Unlike grain oriented silicon steel, where the crystal grains are aligned in a specific direction, CRNGO silicon steel has a random orientation of grains. This isotropic structure allows for uniform magnetic properties in all directions, making it suitable for applications where the magnetic field varies.
2. Uniform Magnetic Properties
One of the key features of cold rolled non-grain-oriented silicon steel is its uniform magnetic properties in all directions, making it appropriate for use in electric-powered cars, transformers, and different electromagnetic devices.
3. Low Iron Loss
This material is designed to have low iron loss, also known as core loss or eddy current loss. This is the energy that is dissipated in the form of heat when the material is subjected to a changing magnetic field. Low iron loss is crucial for the efficiency of electrical devices.
4. High Electric Resistivity
It has a relatively high electric resistivity, which allows for reduced eddy current losses in electric electrical machinery and equipment. This property is vital for maintaining the performance of transformers and other electrical devices, mainly in excessive-frequency packages.
5. Uniform Thickness
The cold rolling process ensures uniform thickness and excellent surface quality, contributing to its magnetic performance and ease of processing.
6. Good Formability
Moreover, non grain oriented silicon steel gives exact formability and weldability, taking into account the manufacturing of complicated shapes and designs in electrical equipment. It can be easily stamped, punched, and formed into complex shapes, providing versatility in manufacturing processes.
7. Corrosion Resistance
While not as corrosion-resistant as some other materials, the insulating coating can be applied to enhance its resistance to oxidation and corrosion.
8. Low Price
CRNGO silicon steel is less expensive than cold rolled grain oriented silicon steel (CRGO silicon steel) and is used when the cost is more important than efficiency.
The market trends suggest a steady increase in the use of cold rolled non grain oriented silicon steel due to its excellent magnetic properties and high performance in electrical applications. These applications include:
1. Electric Motors: The material is used to make the cores of electric motors, whichhelps to reduce energy losses and improve the efficiency of the motor.
2. Generators: In generators, CRNGO silicon steel is used to create the cores, allowing for efficient energy conversion with minimal losses.
3. Transformers: It is also used in the production of transformer cores, where it helps to maintain the efficiency of the energy transfer process.
4. Rotating Machinery: CRNGO silicon steel is incorporated into various rotating machinery such as alternators, dynamometers, and other electromechanical devices to ensure high performance and energy efficiency.
5. Industrial Equipment: It is utilized in a wide range of industrial equipment, including pumps, fans, and compressors, where its magnetic and electrical properties play a crucial role in performance and energy efficiency.
6. Automotive Components: In the automotive industry, CRNGO silicon steel is used in components such as alternator cores and various electromagnetic devices within vehicles.
