Product parameter

Cold-rolled non-oriented silicon steel is a special kind of silicon steel material, which is not subjected to orientation annealing in the process of cold rolling.

Silicon steel is a material in which silicon is incorporated into steel, the main purpose of which is to reduce hysteresis loss and improve permeability, which is used to manufacture the core parts of motors and transformers. Cold rolling refers to the rolling of steel at room temperature to change the shape and thickness of steel. Non-oriented annealing is a heat treatment usually carried out during cold rolling to rearrange the crystal structure so that the steel exhibits excellent permeability properties in a magnetic field. In general, cold-rolled non-oriented silicon steel is a kind of silicon steel material that has been cold-rolled but not annealed.

Material introduction

Silicon steel is a special kind of steel, its main feature is that it contains a high proportion of silicon elements, usually silicon content between 0.8% and 4.8%. The characteristics and applications of silicon steel make it widely used in many fields such as electrical, electronic, communication, automotive and so on.

The characteristics of silicon steel:
High permeability: Silicon steel has high permeability, which means that it can effectively conduct magnetic fields and is an ideal material for manufacturing electrical equipment such as transformers and motors.
Low iron loss: The iron loss of silicon steel is low, that is, the energy loss generated when the magnetic field changes is small, which helps to improve the efficiency of electrical equipment and extend the service life.
Good processing performance: silicon steel has good plasticity, toughness and weldability, easy to process into a variety of shapes and sizes, convenient to manufacture a variety of electrical equipment.
High resistivity: Silicon steel has a high resistivity, which helps to reduce eddy current losses in electrical equipment and improve the efficiency of equipment.
Good corrosion resistance: silicon steel has good corrosion resistance and can be used for a long time in harsh environments.
Silicon steel production process:

The production process of silicon steel is relatively complex, mainly including steelmaking, continuous casting, hot rolling, pickling, cold rolling, annealing and other processes. In the production process, it is necessary to strictly control the ratio of charge, melting temperature, rolling speed and other parameters to obtain high quality silicon steel products.

The following is a detailed introduction to the difference and role of cold-rolled oriented silicon steel and cold-rolled non-oriented silicon steel:

The difference:

Properties: Oriented silicon steel is an important ferrosilicon alloy used in transformer (iron core) manufacturing industry, and unoriented silicon steel is a very low carbon ferrosilicon alloy, its grains are irregularly oriented distribution.
Characteristics: The magnetic properties of oriented silicon steel are strongly directional, with the lowest iron loss and highest permeability in the rolling direction, and high magnetic inductance in a certain magnetization field. Non-oriented silicon steel has good electromagnetic properties and processing properties.
Purpose: Oriented silicon steel is mainly used in transformer manufacturing, while non-oriented silicon steel is widely used in electrical equipment such as motors, generators, transformers.

Functions:

Cold-rolled oriented silicon steel: Because of its superior high permeability and low loss characteristics, it is widely used in the manufacturing of electrical equipment such as transformers and motors, especially in the occasions requiring high efficiency and low energy consumption, such as power, electronics, communications and other fields.
Cold-rolled non-oriented silicon steel: mainly used in generator manufacturing, because it has good electromagnetic properties and processing properties, can meet the requirements of the generator for materials, such as high strength, high conductivity, high corrosion resistance and so on.

In short, although cold-rolled oriented silicon steel and cold-rolled unoriented silicon steel are both silicon steel materials, their properties, characteristics, uses and functions are very different. In practical applications, the appropriate materials need to be selected according to the specific use occasions and requirements.

Product application

Non-oriented silicon steel is a special cold-rolled electrical steel, and its magnetic properties are better than traditional silicon steel. Therefore, non-oriented silicon steel is widely used in the following fields:
1. Power sector
Motor is one of the main application fields of non-oriented silicon steel. Non-oriented silicon steel is used in the core and windings of electric motors, which can improve the energy efficiency and reliability of electric motors. With the wide application of motor in national economy, the market prospect of non-oriented silicon steel is broad.
2. Metallurgical field
In electric arc furnace, induction furnace, intermediate frequency furnace and other metallurgical equipment, non-oriented silicon steel is used as the main material for electromagnetic core, magnetic coil and other components. Its low loss and high permeability characteristics can improve the efficiency of metallurgical equipment and reduce energy consumption.
3. Mechanical field
Non-oriented silicon steel is also widely used in some mechanical transmission systems. For example, in high-speed power tools, positioners, meters and other equipment, non-oriented silicon steel as the core material, can improve the stability and reliability of the system.
4. New energy
The drive motor is one of the three core components of new energy vehicles, and its future development direction is high-speed and high-power. This requires the motor to reduce the volume, weight and iron consumption of the motor as much as possible under the same power, but reducing the volume and weight of the motor will lead to a reduction in motor torque, so it is necessary to increase the motor speed. The high speed and high power of the drive motor also put forward higher requirements for motor materials, especially the fixed rotor core made of non-oriented silicon steel sheets, which not only directly determines the motor power, torque, iron consumption, temperature rise, etc., but also affects the driving range of new energy vehicles.
