⚠ Risk Items
High-frequency harmonic• Select thinner specifications (0.2mm or 0.15mm) of electrical steel • Optimize control strategies or add filters to reduce harmonic content
Enterprise Measure• During the product design phase, harmonic simulation analysis must be conducted compulsorily. If the standards are not met, the product cannot proceed to trial production. • Establish a mechanism for evaluating customer application scenarios. For high-power frequency converters and other sources with strong harmonics, the customer is required to provide harmonic parameters in reverse. • Clearly specify the applicable frequency range and harmonic limits of the product in the technical agreement. Use beyond the specified range will not be covered by warranty.
Dampness / Corrosion• Storage environment humidity should be no more than 60%, and ensure good ventilation and dryness. • Avoid contact with acidic or alkaline corrosive substances. • As soon as processing is completed, assemble or apply anti-rust oil immediately.
Enterprise Measure• Implement digital monitoring of the warehouse environment, with automatic alarm and record-keeping when humidity exceeds the limit. • Develop the "Anti-Rust Operating Procedures for Incoming Materials and Semi-Finished Products", specifying the anti-rust oil model, coating thickness, and validity period. • Incorporate the anti-rust effect into the supplier's quality score and conduct quarterly audits on internal implementation.
Mechanical stress (shearing/pressing)• Use sharp molds to control the blanking gap. If necessary, perform stress-relieving annealing (at 700-800°C). • During the press-fitting process, use torque control to ensure uniform pressure and that it does not exceed the yield strength of the material.
Enterprise Measure• Develop a "Mold Full Life Cycle Management Plan", specifying the mold replacement frequency and wear detection standards • Establish a stress relief annealing process certification system, conducting random inspections on the rate of iron loss change after each batch of annealing • Incorporate shearing burrs and press-fit force into the process capability index (Cpk) monitoring
Bending / Deformation• During design, avoid small radius bends. The minimum bending radius should be at least 10 to 20 times the plate thickness. • During transportation and storage, keep the plate lying flat. Do not lift it at a single point or strike it. • When punching and shearing, control the burrs. When stacking sheets, apply uniform pressure. Do not hammer.
Enterprise Measure• Publish the "Guidelines for Handling, Storage and Processing of Electrical Steel (SOP)", and incorporate it into the mandatory training for employees. • Establish a production line inspection system, with a focus on checking the compliance of the use of lifting devices, molds, and press-fitting fixtures. • Establish a quality assessment and traceability mechanism for the violation of bending behavior.
High-temperature environment• Select insulation coatings that are compatible with the working temperature (organic ≤ 180℃, inorganic up to 800℃) • Optimize the heat dissipation design to reduce the actual operating temperature of the core • Select an electrically conductive steel grade with stable high-temperature performance for magnetic-thermal simulation verification
Enterprise Measure• Establish a material selection review system and dynamically update the "Electrical Steel Selection Comparison Table", clearly defining the material models corresponding to different temperature levels. • Conduct temperature resistance process audits on suppliers, requiring them to provide high-temperature aging test reports. • Develop product limit temperature usage guidelines and incorporate them forcefully into design documents and technical agreements.
