Grain Oriented Electrical Silicon Steel Sheet Slit Coil Product Description
CRGO Slit Coils, also known as Cold Rolled Grain Oriented Steel Slit Coils, are electrical steel products that are widely used in the manufacturing of transformers, inductors, and other power electronic devices.
These coils are made by slitting cold-rolled grain-oriented steel sheets or mother coils into narrower strips, which are then wound into coils. The cold rolling process aligns the crystal grains in the steel, significantly improving the material's magnetic properties.
CRGO Coils offer high magnetic permeability, low core loss, and excellent insulation properties, making them ideal for applications that require high efficiency and low losses. These coils are available in mother form in various sizes (900mm to 1250mm), width shapes, and thicknesses (0.18mm to 0.35mm), allowing manufacturers to choose the right product for their specific needs.
We offer precision cutting services for magnetic core coils, providing various widths to meet customer needs. Our advanced CNC Slitting line with a carbide cutter ensures top-quality results with perfect accuracy. We guarantee that both edges of our slit coils will have a maximum 10-micron burr.
the key aspects that make Oriented Silicon Steel a superior material for electrical appliances.
Superior Magnetic Properties - One of the most significant advantages of Oriented Silicon Steel is its high magnetic permeability. This property allows the material to conduct magnetic fields with minimal resistance or loss, making it an excellent choice for applications where high-performance is essential. By using Oriented Silicon Steel, we can create electrical appliances that can operate at more significant efficiency levels, saving energy and costs.
Low Core Losses - Core loss is a significant issue with electrical appliances, especially motors and transformers. Core losses occur when magnetic fields generate heat, causing a drop in performance and efficiency. Oriented Silicon Steel is designed to minimize core losses, allowing appliances to operate at higher efficiencies and prolonging their lifespan.
Excellent Electrical Resistance - Another critical property of Oriented Silicon Steel is its electrical resistance. This material exhibits high resistivity, which significantly reduces eddy current losses, allowing the steel to perform optimally even at high frequencies.
High Strength and Durability - Our Oriented Silicon Steel sheets are specially designed to exhibit high strength and durability. We use advanced processes and techniques to create steel that can withstand high magnetizing forces without degrading or losing its magnetic properties.
Eco-Friendly - Our Oriented Silicon Steel is an eco-friendly material that conforms to the RoHS standards, making it safe for use in electrical appliances.
The most important purpose of cold-rolled oriented silicon steel belt is for transformer manufacturing, so it is also called cold rolled transformer silicon steel. Compared with the cold-rolled non-oriented silicon steel, the magnetic orientation of the oriented silicon steel is strong.
It has superior permeability and low loss characteristics in the direction of easy magnetization. The iron loss of the orientation steel strip in the direction of rolling is only one third of the horizontal one, and the ratio of the magnetic conductivity is 6:1, and the iron loss is about 1/2 of the hot-rolled belt, and the magnetic conductivity is 2.5 times that of the latter
Our high-quality steel sheets exhibit superior magnetic properties, low core losses, excellent electrical resistance, and high strength and durability, making them the perfect material for your electrical appliance needs. Reach out to us today and let us provide you with top-quality Oriented Silicon Steel products to meet your requirements.
