What is Silicon Steel

Silicon steel, also known as electrical steel, lamination steel, or transformer steel, is a ferritic alloy of iron and silicon that have magnetic properties, which make it useful in motors and transformers. This type of steel material contains 0.5%-4.5% silicon in weight with low carbon of less than 0.08%. The addition of silicon (Si) improves the magnetic softness and increases the electrical resistivity of steel. There are two forms of silicon steel: grain-oriented (GO) and non-oriented (NGO). GO silicon steel can be further subdivided into regular grain-oriented (RGO) and high permeability grain-oriented (HGO) materials. Silicon steel is known for its high permeability and low amounts of core loss, which make it useful in the generation, distribution, and consumption of electricity, such as small to large motors, relays, solenoids, appliances’ motors, wind turbines, cores of transformers, EV, and power generator equipment, etc.

Advantages of Silicon Steel

Low loss and high permeability
A notable feature of Silicon Steel is its low loss and high magnetic permeability. This is due to the reduction of tiny magnetic domain wall losses between the oriented and non-oriented Silicon Steels and the optimization of the size and shape of silicon grains. This low loss and high magnetic permeability enable the Silicon Steel to reduce energy loss when current passes, and provide high-efficiency magnetic permeability.

Reduce eddy current loss
Eddy current losses are generated in an alternating magnetic field, which leads to current consumption and heat generation. Silicon Steels reduce eddy current losses by introducing silicon particles into the material. Silicon’s high resistivity reduces the intensity of eddy currents, thereby reducing energy loss and heat generation. This makes Silicon Steels particularly suitable for use in equipment such as high-frequency transformers and motors.

Suppression of magnetic saturation and noise
The high saturation magnetic induction of Silicon Steel enables it to withstand high magnetic flux density without saturation. By suppressing magnetic saturation, Silicon Steels are able to reduce magnetic field fluctuations in transformers and motors, thereby reducing noise and mechanical vibration. This is very important for equipment that requires low noise and smooth operation.

Environmental protection and sustainability
The production process of Silicon Steels is relatively environmentally friendly. Compared with ordinary steel, the manufacturing process of Silicon Steel involves less energy consumption and resource consumption. In addition, its efficient energy conversion characteristics mean that in equipment using Silicon Steels, less electrical energy is lost, making the entire power system more energy efficient.

Key Properties of Silicon Steels

01/

Resistivity
In comparison to iron, silicon steel shows a significant increase in resistivity. This increase reduces core loss by minimizing the eddy current component, hence improving energy efficiency.

02/

Saturation induction
The degree to which silicon steel can be magnetized, or its saturation induction, is another vital property. The higher the silicon content, the lower the saturation induction. It’s a balancing act between maintaining high resistivity and ensuring adequate saturation induction.

03/

Magneto-crystalline anisotropy and magnetostriction
These properties influence how the material behaves under the influence of magnetic fields and mechanical stress, respectively. While increasing silicon content lowers magnetostriction, the processing becomes more challenging.

04/

Curie temperature
The Curie temperature, which is quite high for iron, can be reduced by alloying elements. However, the decrease doesn’t significantly impact silicon steel users.

Five Tips for Choosing the Right Silicon Steel for Your Application

1. Understand your application requirements
Different applications require different properties. For example, transformers need oriented silicon steel, while rotating machinery might benefit more from non-oriented silicon steel.
2. Consider the cost
Oriented silicon steel tends to be more expensive than its non-oriented counterpart due to the additional processing steps.

Factor in efficiency

Higher silicon content improves efficiency by reducing energy loss. However, too much silicon can make the steel harder to work with.

Think about size

Large components might be better suited to non-oriented silicon steel, which is less sensitive to mechanical strain.

Remember the environment

The operating environment could influence your choice. For instance, silicon steel with higher Curie temperatures may perform better in high-temperature applications.

Features of Silicon Steel

Thanks to the high permeability, low coercivity, and high resistivity of silicon steel, the hysteresis loss and eddy current loss are small.
Silicon steel requires high plasticity, smooth and flat surface, and low harmful inclusion in order to satisfy the process of punching and shearing, improve magnetic induction, and reduce hysteresis loss.
At present, the production process of hot-rolled silicon steel has been eliminated in China and replaced with cold-rolled silicon steel. The iron loss performance of the silicon steel that CUMIC supply far exceeds the iron loss requirements of the international standards.

Silicon Steel Applications Have What Industries

Astronomy, aviation, our country launched the "god six" part of the parts on the use of silicon steel, but the production precision and specifications of this Silicon Steel are customized, and our ordinary use of Silicon Steel is still a big difference, after all, the aerospace engineering can not be sloppy, its various standards are very high.
In electronic equipment, small electronic equipment, the motor is required to produce silicon steel, and some other parts need Silicon Steel to produce.
In a variety of large-scale production machinery and equipment. For example, air compressors, air pumps and other motors with the figure of Silicon Steel, and the requirements of the Silicon Steel is cold rolled Silicon Steel, which can help mechanical equipment to better play its role.
In small appliances, we live in the use of some small home appliances, such as refrigerators, etc., can see the figure of Silicon Steel.

Silicon Steel Iron Core in the Transformer Play What Role

Commonly used transformer core is generally made of Silicon Steel. Silicon steel is a kind of steel containing silicon, its silicon content in. 0.8% ~ 4.8%. Silicon steel to do the transformer core, because the silicon steel itself is a kind of magnetic conductivity is very strong magnetic material, in the energized coil it can produce a larger magnetic induction intensity. Thus can make the transformer size reduction mouth transformer in the AC state [for power loss not only in the coil resistance. Also produced in the alternating current magnetization in the iron core. Usually the power loss in the iron core called 'iron loss', iron loss caused by two reasons one is 'hysteresis loss' and one is 'eddy current loss'.
Hysteresis loss is the iron core in the magnetization process. Mountain in the existence of hysteresis phenomenon and iron loss. The size of this loss and material hysteresis line surrounded by the size of the area is directly proportional to the hysteresis line of silicon steel is narrow, with it as the transformer core hysteresis loss is small, can make its degree of heat greatly reduced.
Transformer work, the coil has an alternating current generated by the magnetic flux is of course alternating. Variable magnetic flux in the iron core to produce induced current. The induced current generated in the core circulates in the plane perpendicular to the direction of the flux, so it is called eddy current eddy current loss also makes the core heat. In order to reduce the eddy current loss, the transformer core with each other insulated Silicon Steel stacked. So that the thirst flow in a narrow circuit, through a smaller cross-section, to increase the eddy current path on the electric limit; at the same time. Silicon in the silicon steel to increase the resistivity of the material. Also play a role in reducing eddy currents
Used as a transformer core, generally choose 0.35 mm thick cold rolled Silicon Steel. According to the size of the required core, it will be cut into long pieces, and then folded into '- day' zigzag or 'mouth' zigzag. Rationally speaking. If in order to reduce eddy currents, the thinner the thickness of the Silicon Steel, the narrower the splicing strip. The better the effect. This reduces the eddy current loss, reduces the temperature rise, but also saves Silicon Steel material but the actual l several production of Silicon Steel core. Not only from the above side of the favorable factors. Because of that production core, to greatly increase the working hours, but also reduce the effective cross-section of the core. Therefore, the use of Silicon Steel transformer core production, to weigh the pros and cons from the specific circumstances, choose the best size.

What are the Classifications of Silicon Steel?

Silicon steels are categorized according to the amount of silicon content and can be divided into two categories:

High silicon silicon steel
High silicon silicon steel, as the name suggests, is a Silicon steel with high silicon content, this silicon steel contains more silicon steel, the higher the content of silicon, the lower the iron loss, the better the effect of its magnetic flux.

Low silicon silicon steel
Low-silicon silicon steel is a silicon steel with low silicon content, this kind of silicon steel due to low silicon content, its resistance is relatively large, iron loss is relatively high.

The classification of silicon steel can be divided into two categories if it is categorized according to its performance:

Hot rolled silicon steel
Hot rolled silicon steel are non-oriented silicon steel, saturation point of about 1.6T, hot rolled silicon steel processing performance is relatively poor, the unit loss is smaller.

Cold rolled silicon steel
Cold rolled silicon steel is divided into oriented silicon steel and non-oriented silicon steel two kinds of magnetic flux density in 1.9T, processing performance is better, magnetic susceptibility performance is also better.

How to Judge the Performance of Silicon Steel from the Silicon Steel Is Good or Bad

Silicon steel wafer hardness, good silicon steel wafer hardness value will have a standard. Hardness is relatively low silicon steel, not conducive to processing, in molding and other aspects of the effect is not good, so we can be based on the hardness of the silicon steel to judge the silicon steel is good.
Silicon steel punching is one of the important standards to measure the good and bad silicon steel, good punching is silicon steel affects the service life of the silicon steel, so it is also important to choose the silicon steel with less burrs.
The magnetic flux of silicon steel, silicon steel of silicon content is also an important criterion affecting the magnetic flux performance of silicon steel, silicon content is too small will increase the resistance, and lead to iron loss of silicon steel, shorten the service life of silicon steel.

How to Distinguish Between Oriented and Non-oriented Silicon Steel Wafers

Through the color to identify, the color of the silicon steel with orientation is white or off-white, while the non-orientation of the silicon steel is to show the ordinary color of the silicon steel. The reason is that the silicon content of these two kinds of silicon steel is different, the silicon content of oriented silicon steel is more than the silicon content of non-oriented silicon steel.
Structure is not the same, there is an orientation of the silicon steel grain is oriented in one direction, and non-orientation of the silicon steel grain is more chaotic, because of the structure of the reason, there is an orientation of the silicon steel than the non-orientation of the iron loss of silicon steel to be small, better efficiency.
Toughness and hardness is not the same, there are oriented silicon steel in the bending of not only will fall gray-white slag, folded a few times may be broken, and non-oriented silicon steel is better toughness, it is difficult to break.
Thickness is not the same, there is an orientation of silicon steel thickness of 0.23-0.35 mm, non-oriented silicon steel thickness of 0.35-0.65. non-oriented Silicon Steel to be much thicker than there is an orientation of silicon steel.
