M4 Grain oriented silicon steel, also known as M4 electrical steel, is a high-quality electrical steel specifically designed for use in transformers, motors, generators, and other electrical devices. This advanced material, composed primarily of iron and silicon, is meticulously processed to achieve a specific grain orientation, which is crucial for its magnetic properties, making it an ideal choice for a wide range of electrical applications.
The production of M4 Grain Oriented Silicon Steel involves a series of carefully controlled steps to ensure the desired grain orientation and magnetic properties.
The raw material (carbon, silicon, iron, etc) is initially melted and refined to achieve the required chemical composition. It is then continuously cast into thin slabs, which are subsequently hot rolled to achieve the desired thickness. The hot-rolled slabs are then annealed to develop the grain orientation and magnetic properties. Next, they will be passed through a series of cold rollers to reduce their thickness and better improve their magnetic properties. After secondary annealing, the silicon steel will be coated with an insulating material, such as varnish or enamel, helping to minimize core losses and ensure optimal performance in electrical applications.

M4 Grain oriented silicon steel is a type of oriented electrical steel. With a silicon level of 3%, it is processed in a way that optimizes the M4 electrical steel’s properties in the rolling direction, resulting in:
1. It has high magnetic permeability, which means it can easily conduct magnetic flux. This property makes it ideal for use in electrical equipment such as transformers, electric motors, and generators.
2. It has low core loss, which means it can efficiently convert electrical energy into magnetic energy and vice versa. This property is important in electrical equipment, as it can help to reduce energy loss and improve the efficiency of the equipment.
3. It increases the magnetic flux density by 30% in the coil rolling direction.
4. It has high saturation induction and low magnetostriction, making it suitable for high-performance electrical equipment, thus contributing to long-term operational reliability.
5. It has good temperature stability, which means it can maintain its magnetic properties even at high temperatures. This property is important in electrical equipment, as it can help to prevent the equipment from overheating and potentially failing.
6. It offers excellent electrical resistivity, reducing eddy current losses and ensuring efficient operation in electrical devices. This property is particularly important in applications where the material is subjected to rapidly changing magnetic fields, such as transformers and electric motors.
M4 Grain-oriented silicon steel is used in a wide range of electrical engineering.
Firstly, M4 grain oriented silicon steel is used in the cores of efficient transformers, including power and distribution transformers, large power transformers, small transformers, current transformers, etc.
Furthermore, it is also used in other types of electrical equipment, such as motors, generators, inductors, chokes, and solenoids, where its superior magnetic characteristics contribute to enhanced performance and longevity.
Finally, it can also used in the construction of renewable energy systems and industrial power systems, contributing to sustainable energy practices and ensuring reliable electricity management.
