Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, China, specializes in precision processing of electrical pure iron materials for critical electromagnetic applications. Our coil slitting service transforms raw pure iron into ready-to-use laminations specifically engineered for transformer cores, delivering exceptional magnetic performance and operational reliability. With stringent quality control throughout our production process, we ensure every slit coil meets the exacting standards required for high-efficiency energy transfer in power systems.
The following technical advantages define our service:
Superior Magnetic Properties: Achieve core losses reduction of up to 15% compared to conventional silicon steel due to minimized hysteresis and eddy current losses.
Precision Dimensional Control: Advanced slitting equipment maintains width tolerances within ±0.1mm for seamless core stacking.
Material Consistency: Guaranteed homogeneity with controlled crystal orientation (Goss texture) through our proprietary annealing process.
Customization Flexibility: Adjust processing parameters including burr control (
Key technical specifications for standard processing:
| Parameter | Capability | Measurement |
|---|---|---|
| Material Thickness | 0.10 - 0.50 | mm |
| Max Coil Weight | 10,000 | kg |
| Slitting Width Range | 20 - 1,200 | mm |
| Permeability (μmax) | ≥ 8,000 | Gauss/Oe |
Our processing directly contributes to transformer performance improvements:
Reduced no-load losses by 12-18% through optimized domain alignment
Enhanced overload capacity due to consistent saturation flux density (≥2.15T)
Lower audible noise generation (3-5dB reduction) from stress-free cutting
Backed by Shanxi Jurun's decade-long metallurgical expertise in Taiyuan, we implement rigorous quality protocols including Epstein frame testing and laser-based dimensional verification. Our production facility operates with ISO-guided procedures (certification details available upon request), ensuring traceability from raw material to finished slit coil. Clients benefit from our technical consultation service for core design optimization and material selection guidance.
Frequently Asked Questions:
Q: What surface protection options are available?
A: We offer optional epoxy coating or temporary rust preventive oil based on storage requirements and downstream processing.Q: Can you process non-standard widths beyond the listed range?
A: Our slitting lines accommodate special widths down to 15mm with modified tooling (additional setup charges apply).Q: How is magnetic permeability verified?
A: Random samples undergo BH curve analysis using permeameters, with test reports provided upon request.Q: What packaging standards do you follow?
A: Standard packaging includes moisture-proof paper and steel strapping. VCI packaging available for export shipments.Q: Do you provide annealing after slitting?
A: Stress-relief annealing (up to 850°C) can be arranged to restore magnetic properties affected by cutting stress.Q: What is your lead time for standard orders?
A: Typical production cycle is 14-21 days depending on order volume and processing complexity.
