Non Oriented Silicon Steel Product Description
Non-oriented silicon steel is a high-quality electrical steel used for various applications in the electrical industry. It is also known as silicon steel or electrical steel, and it has become a popular material for manufacturers of power transformers, electric motors, and generators. The material's unique properties make it an ideal choice for these applications, and it has gained a reputation as being one of the most reliable and efficient materials available.
advantages of electrical steel
One of the main advantages of non-oriented silicon steel is its low core loss. Core loss is the energy that is lost in the form of heat during transformer operation, and it can have a significant impact on the efficiency of electrical equipment. Non-oriented silicon steel has low core loss, which translates to less energy lost and more efficient electrical equipment.
Another advantage of non-oriented silicon steel is its high permeability. Permeability is a measure of how easily a material can be magnetized, and non-oriented silicon steel has a high permeability. This means that it can be magnetized with less current, which leads to less energy wasted during the magnetization process.
The magnetic properties of non-oriented silicon steel are also highly consistent, making it well-suited for use in high-performance electrical equipment. The material's magnetic properties can be customized to suit the specific needs of different applications, and manufacturers can use it to create transformers and other equipment that are optimized for particular voltage levels, frequencies, and power levels.
Non-oriented silicon steel also has excellent resistance to rust and corrosion, which makes it an ideal choice for use in outdoor electrical equipment. It is also highly durable and can withstand extreme temperatures, which makes it suitable for use in harsh environments.
In addition to its excellent properties, non-oriented silicon steel is also easy to manufacture. It can be produced in a variety of shapes and sizes, and it can be easily cut, punched, and stamped to create the necessary shapes for transformers and other electrical equipment. Its ease of manufacturing also means that it is cost-effective, making it an attractive choice for manufacturers looking to produce high-quality electrical equipment at a reasonable cost.
Overall, non-oriented silicon steel is an excellent choice for manufacturers of electrical equipment looking for high-quality, reliable, and efficient materials. Its unique properties, including low core loss, high permeability, customization options, and durability, make it an ideal choice for various applications in the electrical industry. Whether used in transformers, electric motors, or generators, non-oriented silicon steel is a material that delivers reliable performance and energy efficiency.
Cold-rolled non-oriented silicon steel, also known as cold-rolled electrical silicon steel, is mostly used to make generators. Steel strips that have been cold rolled to the final product thickness and have 0.5% to 3.0% silicon content and 0.35mm and 0.5mm thick. In comparison to grain-oriented silicon steel, cold-rolled non-oriented silicon steel has a greater Bs. Its consistent thickness, large size, and smooth surface make it superior to hot-rolled silicon steel in terms of filling factor and magnetic energy.
A. Low iron loss. The most important indicator of quality, all countries in the world classify grades by iron loss value, the lower the iron loss, the higher the grade and the higher the quality.
B. High magnetic induction. Silicon steel sheets with higher magnetic induction can be obtained under the same magnetic field, and the volume and weight of motor or transformer iron cores manufactured with it are relatively small, and silicon steel sheets, copper wires and insulating materials can be relatively saved.
C. High stacking factor. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, and the stacking factor of the iron core is improved.
D. Good filming performance. This is even more important for the manufacture of small and micro motor cores.
E. The surface has good adhesion and weldability to the insulating film, which can prevent corrosion and improve punching performance.
F. Magnetic aging phenomenon is small
G. Silicon steel sheets must be delivered after annealing and pickling.
