Market Insight: Non Oriented Electrical Steel Sheets in Power Industry

Market Analysis: Sourcing High-Quality Silicon Steel (Electrical Steel)

Industrial Demand Drivers

Global demand for non-oriented electrical steel (NOES) is driven by renewable energy expansion, EV adoption, and grid modernization. Transformers and motors account for ~70% of NOES consumption. With energy efficiency regulations tightening (e.g., DOE Tier 4, EU Ecodesign), manufacturers require high-performance NOES to meet compliance. Annual growth of 4.2% in NOES demand is projected through 2030, particularly in emerging markets where infrastructure projects are accelerating. Asia-Pacific contributes 60% of global demand growth, creating urgent need for reliable, cost-efficient suppliers.

Criticality of Material Quality

Core loss, magnetic permeability, and thickness consistency directly impact transformer and motor efficiency. A 0.1 W/kg reduction in core loss saves 1,500+ kWh annually per 1 MVA transformer. Thickness tolerances beyond ±0.02mm increase eddy current losses and reduce stacking factor, raising operational costs. For instance, a 0.2% thickness deviation can increase core losses by up to 15%. Inconsistent grain orientation causes localized saturation, increasing harmonic distortion. Strict control over silicon content (2.8–3.2%) and grain structure is essential for compliance with IEC 60076 and IEC 60404-8-5 standards.

Our Luoyang facility employs advanced continuous annealing lines with precise thermal control, ensuring uniform grain structure across entire coils. This end-to-end rigor delivers transformer-grade performance at 15–20% lower total cost of ownership versus premium global brands, without compromising core loss or flux density metrics. For custom specifications (e.g., high-frequency motor grades), our engineering team provides rapid prototyping and validation support.

Factory Tour: Manufacturing Non Oriented Electrical Steel Sheets

Precision Manufacturing Process & Rigorous Quality Control

At Luoyang Xinzhaohe Aluminum CO., Ltd., our 20+ years of expertise in electrical steel production ensures consistent quality through a tightly controlled manufacturing sequence. Each process stage undergoes rigorous in-process and final QC checks, ensuring compliance with international standards while optimizing cost-efficiency for global transformer manufacturers.

Slitting Process

Precision slitting using CNC-guided shearing with tungsten carbide blades ensures minimal edge deformation. Critical QC parameters include edge burr height (max 0.05mm per ISO 15750) and straightness tolerance (≤0.1mm/m), verified via laser profilometry.

Annealing Process

Controlled atmosphere annealing at 800–850°C under nitrogen-hydrogen mix (95% N₂, 5% H₂) optimizes grain growth for reduced core loss. QC includes magnetic property testing (core loss ≤1.8W/kg @ 1.5T, 50Hz per IEC 60404-2) and grain size verification via ASTM E112.

Insulation Coating

Electrostatic application of phosphate-based insulation coating (1.5±0.2μm thickness) ensures uniform coverage. Adhesion tested via ASTM D3359 tape test (Grade 5), with dielectric strength >2kV per IEC 60404-8-5.

Precision Cutting

Laser-guided cutting with ±0.02mm thickness tolerance. Flatness measured per ISO 11531: ≤1mm/m deviation. Final inspection includes surface defect mapping (no scratches >0.02mm depth) using automated optical inspection (AOI) systems.

Our adherence to these stringent standards ensures superior performance in transformer cores, reducing energy losses and extending service life.
