Baosteel's World's First Capacity Oriented Silicon Steel B23R070

I. Products

Baosteel grain orientated silicon steel B23R070 is a magnetic domain refinement type cold rolled orientated electrical steel with a nominal thickness of 0.23mm, in accordance with the National Standard (GB). The product adopts Baosteel's cutting-edge grain orientation technology and refined magnetic domain treatment process, and has the following core characteristics:

Low iron loss and high magnetic susceptibility: Significantly reduces transformer eddy current loss and improves energy efficiency conversion efficiency.

Excellent coating performance: the surface is covered with an insulating coating that provides high adhesion, heat resistance and strong corrosion resistance, with interlayer resistance ≥30Ω-cm²/face.

As a representative of Baosteel's BeyondECO low-carbon silicon steel series, its carbon footprint is more than 30% lower than conventional processes, which meets the needs of green grid construction.

II. Main uses

B23R070 Specially designed for energy-efficient power equipment, widely used in:

Transformer cores: suitable for oil-immersed distribution transformers (complying with the new GB 20052 energy-efficiency class 2 standard), voltage regulators and extra-high-voltage transformers, reducing no-load losses by more than 15%.

Motors and generators: used in compressor motors, general-purpose motors and small precision motor cores to improve power factor and reduce noise.

High-end electromagnetic components: including magnetic sealers, welding transformers, accelerator electromagnets, etc., which require high magnetic permeability.

III. Storage and maintenance

1，Moisture and rust prevention: The storage environment should be kept dry (relative humidity ≤ 60%), avoiding contact with acid, alkali and other corrosive substances. If stored for a long time, it is recommended to use anti-rust oil or vacuum packaging to protect the surface coating.

2，Physical protection: Avoid mechanical collision or heavy pressure to prevent deformation of steel coils or coating damage. Use special pallets when stacking and control the stacking height to reduce the bottom load.3,33333333332123123123546974124

3，Temperature control: Ideal storage temperature is between 10°C and 30°C to avoid high temperature environment that may cause coating aging or magnetic property degradation.

4，Pre-processing: If cutting or stamping is required, make sure the equipment is clean to avoid scratching the surface with impurities; clean up debris in time after processing to prevent oxidation or degradation of insulating properties.

IV. Payment modalities

Only support T/T payment, the implementation of the FOB standard, the first to determine the variety and grade of silicon steel, sign the contract prepayment of 40%, in the delivery period the goods ready to send to the designated domestic port (such as Tianjin Port), after settlement of the final payment, the goods loaded on the ship.
