As a specialized manufacturer based in Taiyuan, Shanxi Jurun Technology Co., Ltd. delivers precision-engineered DT4C cold rolled pure iron coils that meet rigorous industrial standards. Our slitting service transforms raw coils into ready-to-use strips with exceptional magnetic properties, essential for high-performance electromagnetic applications.
Through advanced cold rolling and precision slitting technologies, we achieve thickness tolerances within ±0.02mm while maintaining the inherent purity of DT4C iron. This ensures minimal core loss and maximum permeability – critical factors for energy-efficient motors and transformers.
Core Specifications:
| Parameter | Specification |
|---|---|
| Material Grade | DT4C (GB/T 6983-2008) |
| Thickness Range | 0.5mm - 2.0mm |
| Width Tolerance | ±0.1mm |
| Maximum Coil Weight | 10 metric tons |
| Surface Roughness (Ra) | ≤0.8μm |
Key Processing Advantages:
- Precision Slitting: Multiple blade configurations for widths from 10mm to 1500mm with camber control under 1mm/m
- Surface Integrity: Oil protection or phosphate coating prevents oxidation during storage and transit
- Material Consistency: Controlled annealing process ensures uniform hardness (45-65 HRB) throughout coils
- Magnetic Properties: Typical core loss ≤ 2.5W/kg @ 1.5T/50Hz with permeability up to 5000μ
Shanxi Jurun's strategic location in China's steel hub enables direct access to premium iron sources and vertically controlled processing. Our ISO-certified facility (certification available upon request) operates 24/7 with dedicated quality teams monitoring every production stage. Clients in transformer manufacturing have reported 15% reduction in eddy current losses when using our slitted coils.
FAQ Section:
-
Q: What distinguishes DT4C from other electrical steels?
A: DT4C contains ≤0.025% carbon with silicon under 0.03%, delivering superior magnetic saturation (2.15T) versus silicon steel alternatives. -
Q: Can you provide specific widths for motor laminations?
A: Yes, our slitting lines can produce strips from 10mm to 1500mm width with ±0.05mm tolerance for precision stacking. -
Q: What packaging options protect against corrosion?
A: Standard VCI paper + waterproof film wrapping available, with custom crate packaging for ocean transport. -
Q: Is annealing performed after slitting?
A: We recommend pre-slit annealing for optimal magnetic properties, though post-slit annealing can be arranged. -
Q: What minimum order quantity applies?
A: MOQ is 3 metric tons per specification, with sample coils available for testing. -
Q: How do you ensure dimensional consistency?
A: Laser gauging systems perform real-time thickness monitoring at 200 points/minute across the strip width.
