27QK120 grain-oriented silicon steel

Performance Features

• Low Iron Loss: In an alternating magnetic field, the energy loss generated when magnetic domains reverse is extremely small, which can significantly reduce the no-load losses and operating costs of transformers and other equipment.

• High Magnetic Induction: Under a certain magnetic field intensity, it can generate a relatively strong magnetic induction intensity, improving the working efficiency and power density of electromagnetic equipment and reducing the volume and weight of the iron core.

• High Permeability: It has good magnetic flux conduction ability, enabling the magnetic field to be concentrated and transmitted more efficiently in the iron core and enhancing the performance of the equipment.

• Good Magnetic Stability: Under different magnetic field intensities and working temperatures, it can maintain stable magnetic properties to ensure the stable operation of the equipment.

Production Process

It is smelted in an oxygen converter. The steel billet undergoes hot rolling, normalizing, cold rolling, intermediate annealing and secondary cold rolling successively to reach the finished product thickness. Then it goes through decarburization annealing and high-temperature annealing, and finally is coated with an insulating layer.
