GB Oriented Silicon Steel & Non-Oriented Silicon Steel
Product Detail
Silicon steel coils, also known as electrical steel or transformer steel, are a type of steel that is specifically formulated to exhibit certain magnetic properties. These coils are commonly used in the manufacturing of power transformers, electric motors, and other electromagnetic devices.
Here are some key details about silicon steel coils:
Composition: Silicon steel coils are made primarily of iron, with silicon being the main alloying element. The silicon content typically ranges from 2% to 4.5%, which helps to reduce the magnetic losses and improve the electrical resistivity of the steel.
Grain orientation: Silicon steel coils are known for their unique grain orientation. This means that the grains within the steel are aligned in a specific direction, resulting in improved magnetic properties and reduced energy losses.
Magnetic properties: Silicon steel coils have high magnetic permeability, which allows them to easily conduct magnetic flux. This property is essential for efficient energy transfer in transformers and other electromagnetic devices.
Lamination: Silicon steel coils are typically available in laminated form. This means that the steel is coated with a layer of insulation on each side to create an insulated core. The lamination helps to reduce eddy current losses, improve energy efficiency, and minimize electrical noise.
Thickness and width: Silicon steel coils are available in various thicknesses and widths to cater to different applications and manufacturing requirements. The thickness is usually measured in millimeters (mm), while the width can vary from narrow strips to wider sheets.
Standard grades: There are several standard grades of silicon steel coils, such as M15, M19, M27, M36, and M45. These grades differ in terms of their magnetic properties, electrical resistivity, and application suitability.
Coating: Some silicon steel coils come with a protective coating to prevent rust and corrosion. This coating can be either organic or inorganic, depending on the specific requirements of the application.

Features
When referring to "prime" silicon steel coils, it typically means that the coils are of higher quality and meet certain industry standards. Here are some additional features that may be associated with prime silicon steel coils:
Superior magnetic properties: Prime silicon steel coils often exhibit excellent magnetic properties, including high magnetic permeability, low core losses, and low hysteresis losses. These features make them ideal for applications where efficient energy transfer and minimal losses are crucial.
Highly uniform grain orientation: Prime silicon steel coils typically have a uniform grain orientation throughout the coil. This uniformity ensures consistent magnetic properties in all directions, resulting in improved performance and reliability of electromagnetic devices.
Lower specific total loss: Prime silicon steel coils are designed to have lower specific total loss, which refers to the total amount of energy lost per unit volume of material. A lower specific total loss indicates higher energy efficiency and reduced operating costs.
Narrower thickness and width tolerances: Prime silicon steel coils often have tighter tolerances for thickness and width compared to standard coils. These tighter tolerances ensure more precise dimensions, which can be critical for certain applications and manufacturing processes.
High-quality surface finish: Prime silicon steel coils are typically finished with a smooth and defect-free surface to minimize the risk of electrical and mechanical issues. A high-quality surface finish also allows for improved bonding and insulation for laminated cores.
Certifications and compliance: Manufacturers of prime silicon steel coils often ensure that their products meet or exceed industry standards and certifications, such as ASTM (American Society for Testing and Materials) or IEC (International Electrotechnical Commission) specifications. This ensures that the coils are of high quality and suitable for demanding applications.
Consistent and reliable performance: Prime silicon steel coils are manufactured to provide consistent and reliable performance over their service life. This means that the coils should maintain their magnetic properties and minimize energy losses even under varying operating conditions.
Application
Here are some common applications of silicon steel coils:
Transformers: Silicon steel coils are extensively used in the manufacturing of transformers. They are used for the core of both power transformers and distribution transformers. The high magnetic permeability and low core losses of silicon steel make it ideal for efficiently transferring electrical energy between different voltage levels.
Inductors and Chokes: Silicon steel coils are also used for the cores of inductors and chokes, which are crucial components in electronic circuits. The high magnetic permeability of silicon steel allows for efficient energy storage and release, reducing power losses in these components.
Electric Motors: Silicon steel coils are widely used in the stator cores of electric motors. The high magnetic permeability and low core losses of silicon steel help to improve the motor's efficiency by reducing energy losses due to hysteresis and eddy currents.
Generators: Silicon steel coils find application in the stators and rotors of generators. The low core losses and high magnetic permeability of silicon steel help in efficient power generation by reducing energy losses and maximizing magnetic flux.
Magnetic Sensors: Silicon steel coils can be used as the cores in magnetic sensors, such as inductive proximity sensors or magnetic field sensors. These sensors rely on changes in magnetic fields for detection, and the high magnetic permeability of silicon steel enhances their sensitivity.
Magnetic Shielding: Silicon steel coils are used to create magnetic shielding for various components and devices. The low magnetic reluctance of silicon steel allows it to divert and confine magnetic fields, protecting sensitive electronics from unwanted electromagnetic interference.
It's important to note that these are just a few examples of the many applications silicon steel coils can be used for. The specific application and design requirements will determine the specific type, grade, and characteristics of silicon steel to be used. Consulting with a professional in the field or referring to manufacturer specifications will help in selecting the right silicon steel coil for a particular application.
Packaging & Shipping
Packaging:
Secure Stacking: Stack the silicon steels neatly and securely, making sure they are correctly aligned to prevent any instability. Secure the stacks with strapping or bandages to prevent movement during transport.
Use protective packaging materials: Wrap them in moisture-resistant materials (such as plastic or waterproof paper) to protect them from water, humidity and other environmental factors. This will help prevent rust and corrosion.
Shipping:
Choose the right mode of transport: Depending on the quantity and weight, choose the appropriate mode of transport, such as flatbed truck, container or ship. Consider factors such as distance, time, cost and any transport regulatory requirements.
Secure the goods: Use strapping, supports or other appropriate methods to properly secure the packaged silicon steel stacks to the transport vehicle to prevent shifting, sliding or falling during transport.
