Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, China, specializes in manufacturing premium cold rolled DT4C silicon steel coils engineered for high-performance electrical applications. Our coils deliver exceptional magnetic properties essential for energy-efficient transformer and electric motor operations, helping global clients achieve superior equipment performance while reducing operational costs.
Manufactured with precision-controlled cold rolling technology, these coils offer consistent thickness and uniform grain orientation critical for minimizing core losses. The DT4C grade silicon steel features optimized silicon content that significantly enhances magnetic permeability while maintaining excellent mechanical workability during core fabrication processes.
- Material Composition: Iron-Silicon alloy with controlled carbon content
- Standard Thickness Range: 0.18mm - 0.65mm (custom thickness available)
- Standard Width Range: 600mm - 1250mm (slitting services offered)
- Surface Finish: Smooth matte finish with optional phosphate or chromate insulation coating
- Magnetic Properties: High saturation flux density (1.8T+) and low watt/kg loss characteristics
| Property | Value | Test Standard |
|---|---|---|
| Core Loss (P1.5/50) | ≤ 4.0 W/kg | ASTM A804 |
| Magnetic Induction (B50) | ≥ 1.65 T | IEC 60404-8-4 |
| Coating Resistance | ≥ 5 Ω·cm² | ASTM A717 |
- Energy Efficiency: Reduced hysteresis and eddy current losses translate to lower operating temperatures and decreased electricity consumption in transformers and motors
- Manufacturing Flexibility: Excellent punching and blanking characteristics allow complex core shapes without edge cracking
- Thermal Stability: Maintains consistent magnetic properties across operating temperatures from -40°C to 150°C
- Vibration Damping: Superior magnetostriction properties reduce audible noise in electrical equipment
Shanxi Jurun Technology leverages Taiyuan's strategic position in China's steel industry to maintain stringent quality control throughout production. Our manufacturing facilities implement statistical process control (SPC) methodologies to ensure batch-to-batch consistency in magnetic properties and dimensional tolerances. Each coil undergoes multiple inspection checkpoints including laser measurement for thickness uniformity and Epstein frame testing for magnetic verification.
For transformer manufacturers, our DT4C coils enable higher power density designs through improved space factor and thermal management. Motor producers benefit from reduced iron losses that contribute to higher IE efficiency class ratings. The material's consistent performance supports compliance with international energy conservation standards for electrical equipment.
