Baosteel B20R060 Magnetic Domain Refinement Silicon Steel Iron Loss as Low as 0.60W/kg

I. Products

Baosteel B20R060 is a representative product of domestic high-performance cold-rolled oriented silicon steel, which is manufactured with the fourth-generation magnetic domain control technology, and its core indexes have reached the international leading level. Its iron loss value (P1.7/50) ≤ 0.60W/kg, magnetic susceptibility (B800) ≥ 1.90T, thickness accuracy ± 0.003mm, suitable for high-energy-efficiency power equipment manufacturing needs. It has passed ISO9001, IEC60404 and other authoritative certificates, and is widely used in the field of new energy and smart grid, and is the designated material for ‘Recommended Catalogue of Industrial Energy Saving Technology and Equipment’ of the Ministry of Industry and Information Technology.

II. Main uses

1, energy-saving power equipment

Distribution transformer: meets the national level energy efficiency (S15) standard, with an annual energy saving of over 5,000 kWh for a single unit.

Extra-high-voltage converter: core component for supporting ±1100kV extra-high-voltage direct current transmission project.

2, new energy system

Photovoltaic / wind power: inverter transformer, converter core key materials

Energy storage equipment: high-frequency transformer core preferred solution

3, high-end industrial manufacturing

Servo motors: 15% increase in power density to help industry 4.0 upgrade

Electromagnetic equipment: induction furnace, induction heater and other high-frequency application scenarios.

III. Storage and maintenance

To ensure stable performance and long service life of B20R060, the following storage specifications should be strictly observed:

1, Environmental control:

Humidity: the relative humidity of the storage environment should be ≤60%, to avoid humidity triggering coating peeling or rusting; long-term storage is recommended to use vacuum packaging or anti-rust oil protection.

Temperature: the appropriate temperature is 10°C-30°C, to avoid high temperatures leading to magnetic performance degradation or coating aging.

2, physical protection:

Steel coils need to be placed horizontally on special pallets, stacking height of no more than 3 layers, to prevent deformation; cut edge materials need to avoid mechanical collision, burr height should be ≤ 0.02mm.

Use nylon sling when transporting, prohibit wire rope from directly touching the surface of steel coil to prevent scratching the insulation layer.

3, Pre-processing treatment:

Processing equipment needs to be clean and free of impurities, and debris should be cleaned up in time after stamping to prevent oxidation;

The internal stress needs to be controlled when shearing and slitting to avoid the deviation of shearing edge more than 1mm.

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.
