Grain-oriented Silicon Steel Sheet

The grain-oriented silicon steel sheet is a sheet material specially made for power transformer and special transformer cores. During the shearing process, we cut strictly along the rolling direction of the silicon steel coil. This ensures that the magnetic property orientation of every sheet is exactly the same. This consistency directly determines the overall permeability and no-load loss level of the assembled core. We use genuine grain-oriented silicon steel coils from Baowu and Ansteel. The main thickness options are 0.23mm, 0.27mm, and 0.30mm. These suit different efficiency levels. Our grain-oriented silicon steel sheet is cut for performance.

Our company has 26 years of experience in silicon steel sheet processing. All 15 shearing lines use CNC automation. The computer precisely controls the cutting length and angle based on the layout plan. For grain-oriented steel, the deviation between the cutting direction and the rolling direction must be kept within a very small angle. Otherwise, the material's low-loss properties are significantly reduced. Our equipment has automatic straightening and angle calibration functions. Every time we change a coil, our technicians verify the cutting direction. This ensures it meets our process standards. Our grain-oriented silicon steel sheet is made with precision.

Superior Cut Quality for Better Lamination

The cut quality of the sheet directly affects the lamination factor and eddy current loss of the core. Our shearing lines are equipped with high-hardness alloy disc cutters. These produce smooth cuts and flat cross-sections. Burr height is strictly controlled within industry standards. Our inspectors use burr measuring instruments to sample each batch. We produce sheets suitable for transformer cores with voltage ratings from 10kV to 110kV. You just need to provide the drawings. We will process the sheets to your specifications. Our grain-oriented silicon steel sheet meets your exact requirements.

Additional Services for Easy Assembly

For clients with very strict dimensional requirements, we offer higher-precision cutting services. Some transformer core joint designs require specific angle matching. We can preset the corresponding angle parameters on the shearing line. This ensures the end angle of every sheet is exactly the same. We also offer stamping or ink-jet marking services. This helps you quickly identify the rolling direction and stacking sequence during lamination. We hope our detailed processing services make your subsequent lamination work easier. Our grain-oriented silicon steel sheet is designed for your convenience.
