To achieve dimensional precision of silicon steel sheets, systematic optimization is required across multiple aspects including material selection, processing technology, equipment precision, and quality control. The key measures are as follows:   Optimize Process Parameters‌: Precisely control cutting speed, feed rate, and pressure in stamping, shearing, and other processes to reduce vibration and material deformation during processing, thereby improving dimensional consistency. Adopt High-Precision Processing Equipment‌: Use CNC punching machines, laser cutters, or fully automatic lamination shearing lines with high repeat positioning accuracy to ensure dimensional deviations are minimized. For example, Guilin Juntaifu Electric Co., Ltd. achieved precise stacking of silicon steel sheets with millimeter-level accuracy through AI vision and robotic collaborative operations. Strictly Control Environmental Factors‌: Process in a constant-temperature workshop to avoid dimensional instability caused by thermal expansion and contraction of silicon steel sheets due to temperature fluctuations. Enhance Detection and Feedback Mechanisms‌: Increase the frequency of online inspections, using coordinate measuring machines (CMM), AI vision systems, and other tools for real-time dimensional monitoring, and feed data back to the control system for dynamic correction. Use Precision Fixtures and Positioning Devices‌: Design high-rigidity, low-deformation dedicated fixtures, and adopt positioning devices for silicon steel lamination (e.g., those from Shijiazhuang Hengchuang Electric) to ensure precise positioning of each sheet during lamination, improving overall core quality. Material Pre-treatment and Quality Screening‌: Perform aging treatment on silicon steel sheets to eliminate internal stresses, and screen out materials with excessive thickness deviations before processing using screening modules to ensure raw material consistency. Apply Error Compensation Technology‌: Compensate for systematic errors in equipment (e.g., lead screw backlash, guide rail wear) through software to further enhance processing precision. Through these comprehensive measures, dimensional precision of silicon steel sheets can be significantly improved, meeting the stringent requirements of high-performance motors, transformers, and other equipment for core materials.

As the global economy faces a potential downturn in 2026, silicon steel producers must proactively adapt to mitigate risks and maintain competitiveness.

Non-oriented electrical steel and grain-oriented electrical steel are the two main types of electrical steel (silicon steel), with their core differences lying in crystal structure, magnetic properties, and application scenarios. Below is a detailed comparison:   Crystal Structure and Magnetic Properties‌ ‌Non-oriented steel‌: Grains are randomly distributed, exhibiting isotropic magnetic properties (magnetic performance is essentially consistent in all directions). It has high magnetic induction (Bs), but relatively higher iron loss and lower permeability. ‌Oriented steel‌: Grains are highly aligned along the rolling direction, exhibiting strong directionality. It has high permeability and extremely low iron loss in the rolling direction, but significantly reduced magnetic performance in the transverse direction.   Chemical Composition‌ ‌Non-oriented steel‌: Lower silicon content (typically 0.5%–3.0%). ‌Oriented steel‌: Higher silicon content (≥3.0%), with the addition of carbon (0.03%–0.05%) and inhibitors to control grain orientation.   Production Process‌ ‌Non-oriented steel‌: Relatively simple process involving hot rolling, cold rolling, and annealing, resulting in lower production costs. ‌Oriented steel‌: Requires complex processes (e.g., high-temperature annealing, inhibitor treatment) to form grain orientation, making production more difficult and costly.   Application Scenarios‌ ‌Non-oriented steel‌: Primarily used in rotating electrical machinery (e.g., generators, motors) cores, where isotropic materials are needed due to varying magnetic field directions. ‌Oriented steel‌: Used in transformer cores, where fixed magnetic field directions require low loss and high permeability along the rolling direction.   Performance Comparison‌   Property Non-oriented Steel Oriented Steel   Iron Loss Higher Extremely low (approx. half that of non-oriented steel)   Permeability Lower High (permeability in rolling direction is 2.5 times higher)   Magnetic Anisotropy None Significant (optimal performance in rolling direction)   Summary‌: Non-oriented steel is suitable for applications requiring multi-directional magnetization, such as motors, while oriented steel is specifically designed for fixed magnetic field devices like transformers, emphasizing low loss and high permeability. Selection should be based on specific application requirements.
