Non-oriented electrical steel FAQS

What is non-oriented electrical steel?

Non-oriented electrical steel (NOES) is a kind of electrical steel made by special process. This steel is highly valued for its unique properties, which make it an essential material in the production of electric motors and other appliances. Non-oriented silicon steel is an indispensable silicon-iron soft magnetic alloy with extremely low carbon content in electric power, electronics and military industries, and it belongs to ferromagnetic material. This paper introduces the development status of non-oriented silicon steel in my country in recent years and makes a prospect for the future development trend. The production process of non-oriented silicon steel and the performance requirements of non-oriented silicon steel are introduced, and the main factors affecting non-oriented silicon steel are analyzed at the same time Keywords: non-oriented silicon steel: production process: performance 1 Introduction to non-oriented silicon steel It is an extremely low-carbon ferrosilicon soft magnetic alloy that is indispensable to the electric power, electronics and military industries. It is mainly used as the iron core of various motors, generators and transformers. Non-oriented silicon steel is a ferrosilicon alloy with very low magnetic content. In the steel plate after deformation and annealing, the grains are distributed in random orientation.

What are the main characteristics of non-oriented electrical steel?

These steels also have low hysteresis loss and high electrical resistivity

Non-oriented electrical steels have a variety of properties that make them ideal for use in electrical applications. First, these steels have low hysteresis losses. This means they don’t lose a lot of energy when exposed to a magnetic field, making them more efficient than other types of steel. Second, these steels have high electrical resistivity. This means they are resistant to electrical current, which makes them less likely to overheat and fail in electrical applications.

These steels are commonly used in transformer cores and motor laminations

Non-oriented electrical steel is a steel commonly used in transformer cores and electric motor laminations. This steel is uniquely magnetic, making it ideal for use in these applications. Non-oriented electrical steel is produced through a cold-rolling process, which helps ensure that the final product has the desired magnetic properties.

Will non-oriented electrical steel be magnetically polarized?

Non-oriented electrical steel does not undergo magnetic polarization in either direction. This means they can be used in a variety of applications where magnetic fields are not required. Non-oriented electrical steels are commonly used in transformer cores, induction motors and generators.

What is the process flow of non-oriented electrical steel?

Smelting vacuum treatment>continuous casting>hot rolling>normalization>cold rolling>annealing>insulating coating

What is the product specification of non-oriented electrical steel?

Steel plate specification and size: the thickness is 0.35, 0.50, 0.65mm, the width is 800-1000mm, and the length is ≤2.0m.

What is the performance of non-oriented electrical steel?

1. Low iron core loss and low electrical steel loss, which can not only save a lot of electric energy, but also prolong the life of the motor and simplify the cooling device
2. High magnetic induction

What are the composition characteristics of non-oriented electrical steel?

Non-oriented electrical steel has a higher content of silicon and aluminum, and non-oriented electrical steel has high levels of silicon and aluminum. These two elements are key to steel’s performance in electrical applications. Silicon increases the strength and wear resistance of steel. Aluminum makes steel conductive. The high content of these two elements makes non-oriented electrical steel ideal for use in electrical applications where strength and electrical conductivity are required.

Are there grades for non-oriented electrical steel?

There are many different grades of non-oriented electrical steel, each with its own unique properties. The most common grades are:

Grade A – This is the most basic grade of non-oriented electrical steel and is typically used in applications where cost is a major consideration. Grade A steel has good magnetic properties and good mechanical strength, but is not particularly resistant to corrosion or heat.

Grade B – This grade is higher than Grade A, with better magnetic properties and better resistance to corrosion and heat. Grade B steel is commonly used in electric motors and generators.

Grade C – The highest grade of non-oriented electrical steel, Grade C offers the best combination of magnetic properties, mechanical strength and resistance to corrosion and heat. Grade C steels are used in performance-critical applications such as large electric motors and generators.

What is the difference between non-oriented electrical steel and grain-oriented electrical steel?

1. Although the two electrical steels are cold-rolled silicon steel sheets, their silicon content is different. The silicon content of cold-rolled non-oriented silicon steel sheet is 0.5%-3.0%, and the silicon content of cold-rolled oriented silicon steel sheet is above 3.0%.
2. The difference in production process and performance: non-oriented silicon steel sheet has relatively lower process requirements than oriented silicon steel sheet
3. Different product specifications: Non-oriented electrical steel is cold-rolled to the thickness of the finished product, and the supply state is mostly steel strips with a thickness of 0.35mm and 0.5mm; the thickness of the finished cold-rolled oriented electrical steel is 0.28, 0.30 or 035mm.

What are the applications of non-oriented electrical steel?

Non-oriented electrical dry steel can be applied to the following products：

1. Small and medium power transformers，
2. voltage regulators, reactors, magnetic amplifiers，
3. Transformers，

4.TV, radio transformers，

5.Welding transformers，etc.
