I. Products
As a representative product of ultra-high magnetic susceptibility orientated silicon steel, Baosteel B30R105 is a core soft magnetic material designed for high-efficiency power equipment. The product is produced by Baosteel's own integrated and innovative technology, which precisely controls grain orientation to form {110} Gaussian weave, giving it excellent electromagnetic properties in the rolling direction. The product meets the requirements of international standards such as GB/T 2521-2008, JIS C2553-2000 and EN10107:2005, and its comprehensive technical performance reaches the global advanced level.
Key performance parameters of the products include:
Thickness specification: 0.30mm standard thickness, balanced material strength and electromagnetic properties.
Magnetic susceptibility: B800 ≥ 1.88T (test conditions: 800A/m magnetic field strength).
Iron loss control: P1.7/50 ≤ 1.05W/kg (iron loss value at 1.7T magnetic susceptibility, 50Hz frequency).
Coating Characteristics: Surface covered with high performance insulating coating, effectively suppressing eddy current loss.
II. Main uses
With its high permeability and low loss characteristics, B30R105 has become a key material for energy efficiency upgrading of modern power equipment:
1, Power Transformer Field
It is especially suitable for the manufacture of ultra-high voltage large transformers of 500kV and above, and has been technically certified by the Three Gorges Project and other national projects.2 Its low iron loss characteristics can reduce the no-load loss of the transformer by 20-30%, which significantly reduces the waste of energy in the process of power transmission and distribution. When applied to oil-immersed transformers, it can reduce no-load loss by 20-30%. When applied to oil-immersed transformers, it can effectively control the temperature rise of the iron core and extend the service life of the equipment.
2, reactor and ballast field
in the reactor core shows excellent magnetic saturation characteristics (B800 ≥ 1.88T), especially suitable for the manufacture of high-precision current sensors, inductive ballasts and other devices. Its grain orientation technology can accurately control the direction of the magnetic circuit, improve the electromagnetic conversion efficiency, and reduce the size of the equipment by more than 15%.
3, High-end motors and generators
As a core material for new energy vehicle drive motors, industrial inverter motors and generators, its low iron loss characteristics can effectively reduce eddy current loss under high frequency operating conditions and improve the energy efficiency of motors. 0.30mm thickness design takes into account the control of high-frequency loss and mechanical strength of the core, which is especially suitable for applications of motors with high rotational speeds of more than 10,000rpm.
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's B30R105 oriented silicon steel represents the current high level of power electronic material technology, which achieves the best balance between magnetic inductance and iron loss characteristics through optimised grain orientation control. As a high-performance material verified by national projects such as the Three Gorges Project, it shows significant advantages in the fields of ultra-high voltage transformers, precision reactors and high-efficiency motors, and can help equipment manufacturers to improve the energy efficiency level of their products and reduce the operating costs of their systems.
Baosteel has a world-class production line and a complete quality assurance system, with a world-leading production capacity of 500,000 tonnes/year of high-grade silicon steel. The company continues to promote green manufacturing technology upgrades, the recent implementation of the rolls of automatic transport storage system and other intelligent projects (scheduled to go into operation in October 2025) will further guarantee the consistency of products and delivery stability. Choosing Baosteel B30R105 is not only choosing a high-quality material, but also choosing a technical guarantee system that runs through the whole process of R&D, production and application.
