Baosteel B27R090 orientated silicon steel: 0.27mm high magnetic susceptibility and low iron loss, core material for transformers and motors

I. Products

Baosteel B27R090 is a cold rolled grain orientated silicon steel with a precisely controlled thickness of 0.27mm (tolerance ±1%) and a special insulating coating on the surface, which combines high adhesion, corrosion resistance and excellent interlayer insulation properties. As a representative product of Baosteel's high-end electrical steel, its core advantages include:

1, excellent electromagnetic performance: iron loss (*P1.7/50*) is as low as R090 grade (≤0.90W/kg), and magnetic susceptibility (B8) reaches more than 1.88T, which significantly reduces the power loss;

2, process precision: thickness uniformity (longitudinal/transversal deviation <1%), high flatness of the plate, and the stacking coefficient is increased by more than 15%; environmental protection and energy saving: it meets the requirement for uniform thickness (longitudinal/transverse deviation <1%) and high flatness of plate, and the stacking factor is increased by more than 15%; environmental protection and energy saving: it complies with the requirements of Baosteel, and has high adhesion, corrosion resistance and excellent interlayer insulation performance. More than 15%;

3, environmental protection and energy saving: in line with the trend of green manufacturing, to help upgrade the energy efficiency of power equipment.

II. Main uses

B27R090 is dedicated to the manufacture of cores for high-efficiency power equipment, including:

?? Transformers: small power transformers, welding transformers, voltage regulators, reducing no-load losses by 30%;

?? Motor systems: compressor motors, general-purpose motors, and precision motors, improving torque density and energy efficiency;

?? Emerging Fields: magnetic cores for electric vehicle charging piles, electromagnetic components for renewable energy power stations.

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.

V. Summary

Baosteel B27R090 orientated silicon steel defines the industry benchmark with low iron loss, high magnetic susceptibility and precise plate shape, which is suitable for high-end transformers and high-efficiency electric motor core components, and helps to upgrade electric power equipment under the goal of ‘double carbon’. As the technology leader of Chinese silicon steel (Baosteel's global debut of B27R080/B30R090 series), B27R090 has been localised and supplied stably, and its technical indexes have reached the international leading level.
