Baosteel B18P070 High Magnetic Susceptibility Silicon Steel Sheet

I. Products

Baosteel B18P070 is an ultra-high magnetic polarisation strength oriented silicon steel with a thickness of 0.18mm, belonging to the high-end series of Baowu silicon steel products. Its core magnetic performance parameters include: low iron loss: P₁. ₇/₅₀ ≤ 0.69 W/kg, P₁. ₅/₅₀ ≤ 0.51 W/kg, which significantly reduces energy loss;

High magnetic polarisation strength: J₈₀₀ ≥ 1.90 T, which improves the efficiency of the magnetic conductivity by more than 15% and ensures highly efficient Electromagnetic conversion;

Advanced technology: laser scribing and magnetic domain refinement technology, grain orientation up to 95%, material consistency certified by ISO9001.

II. Main uses

Designed for high energy-efficiency power equipment, applicable to:

1, high-end transformer core: meet the new national standard ‘power transformer energy efficiency limit value and energy efficiency class’ Grade 1 energy efficiency requirements, suitable for ultra-high-voltage transformers, distribution transformers;

2, green energy equipment: wind power transformers, hydroelectric power plant transmission equipment (such as the Baihetan hydroelectric power plant project), to support the ‘West-East power transmission’ strategy 510; 3, precision motors and generators: improve equipment power density, reduce temperature rise, extend service life 19. "

3, precision motors and generators: to improve the power density of the equipment, reduce temperature rise, and extend the service life.

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.
