B23R080 Oriented Silicon Steel coil

B23R080 is a high-permeability grain-oriented silicon steel that represents the pinnacle of domestic manufacturing standards and is hailed as a "work of art" among steel products. The grade designation is clearly defined: "B" stands for Baosteel, "23" indicates a nominal thickness of 0.23 mm, "R" denotes domain refinement technology (laser etching), and "080" indicates that its iron loss value (P1.7/50) does not exceed 0.80 W/kg.

This product is manufactured using a cold-rolling process and features a semi-organic or inorganic insulating coating on its surface, offering excellent interlayer resistance and adhesion, which effectively suppresses eddy current losses. B23R080 offers exceptional magnetic properties: its magnetic flux density (B800) exceeds 1.87 T, and its iron loss is significantly lower than that of ordinary silicon steel sheets, enabling a substantial reduction in power losses in equipment such as transformers.

Selecting the right 0.23mm oriented silicon steel coil directly impacts your transformer's total cost of ownership. Here are the standout benefits B23R080 brings to your core‑building process:

 

Ultra‑low core loss – The 0.80 W/kg maximum P₁.₇/₅₀ cuts no‑load energy consumption and helps products comply with IEC 60076‑20 and other efficiency regulations.

 

High magnetic permeability – Lower magnetizing current reduces both copper losses and audible noise, delivering a quieter, cooler‑running transformer.

 

Precise thickness control – A tight gauge tolerance across the coil width guarantees a high lamination stacking factor and consistent flux density distribution.

 

B23R080 is primarily used in the manufacture of cores for high-efficiency, energy-saving power equipment and serves as a key material for improving energy efficiency. Specific applications include:

 

- Power transformers and distribution transformers: Used in the manufacture of cores for oil-immersed and dry-type transformers, it is particularly suitable for transformers with high energy efficiency ratings (such as Class 1 energy efficiency), effectively reducing no-load losses.

 

- Ultra-high voltage and large-scale engineering projects: With stable product performance, it has been successfully applied in the manufacture of large transformers with voltage ratings of 500 kV and above for the Three Gorges Project, replacing imported products and ensuring national power security.

 

- Reactors and current transformers: Suitable for the manufacture of cores for various types of reactors and current transformers, providing stable magnetic properties.

 

Noise-Sensitive Environments: Certain derivative models (such as B23R080-LM) feature optimized magnetostriction, resulting in lower operating noise. They are particularly suitable for installation in urban substations, office buildings, and data centers-locations with strict noise restrictions.

 

1. Environmental control:

- The storage area needs to be kept sealed to ensure that the temperature difference between the steel coil temperature and the dew point of the storage area is ≥5°C to avoid moisture condensation leading to rust.

- If stored for more than half a year, the integrity of the packaging needs to be checked, and coils damaged in transport should be resealed and wrapped with rust-proof paper.

 

2. Rust treatment:

- Coils found to be rusty should be used on a priority basis to avoid further oxidation.

- If necessary, sealing treatment can be carried out and professional anti-rust coating is chosen to protect the edges.

 

3. Handling specification:

- Avoid collision or scratching the surface coating during lifting, which will affect the electromagnetic performance.

Transporting ultra‑thin electrical steel requires rigorous care. Every B23R080 0.23mm oriented silicon steel coil leaving GNEE's warehouse is packed according to export‑grade standards:

• Inner rust‑preventive paper and VCI film protect the strip from moisture and salt‑laden air during ocean transit.
• The coil is mounted on a reinforced wooden pallet or steel skid, then secured with radial and circumferential steel strapping.
• Edge protectors prevent mechanical damage to the slit edges, preserving the coating integrity.
• Each package is clearly labeled with coil ID, dimensions, weight, and handling instructions.

What is grain-oriented silicon steel?

Grain-oriented electrical steel is a crucial material in the production of energy-efficient transformers and large, high-performance generators. In the form of laminated, wound, or punched sheets, it is the essential core material of distribution transformers, power transformers, and small transformers.

 

What is the difference between CRC and Crno?

CRCA is used to manufacture various products, such as household appliances, automobiles, and construction materials. On the other hand, CRNO is used in electrical engineering applications and is crucial in producing transformers, motors, and generators.
