Laser-oriented Silicon Steel

The laser-oriented silicon steel , one of the most widespread type of silicon steel in the world now, is delicated to lower cost and promote efficiency. In order to refine the magnetic domains and lower the iron loss, laser is applied to the surface of oriented silicon steel. Taking advantage of the characteristics of the laser for the rapid heating and cooling partly, can promote microplastic deformation and high-density dislocation in the heated area, reducing the length of the main domain of the oriented silicon steel. Laser-oriented silicon steel is more efficient and has better effect than any other products.

The characteristics of the laser-oriented silicon steel

(1) Stable Laser Processing

BaoSteel is the first one equipped with the latest on-line laser processing machine which has reached the highest international scoring speed. With the large-scale and efficient production of laser processing, laser-oriented silicon steel can meet the mass export demand of high-quality production.

(2) Superior Processing Quality

The Intelligent self-feedback controlled "coating traceless" high-quality in-line laser technique is used in the process of Laser-oriented silicon steel which makes the processing improvement rate is 1~2 grades higher than others by traditional processing method.

(3)Less Influence On Insulating Coat

The surface of silicon steel is coated with a layer of inorganic insulating coat.But when the laser processing is used, the laser machine is not in direct contact with the silicon steel which ensure n ensure excellent interlaminar insulation and the lamination factor. Closer combination of

coat and substrate give rise to good adhesiveness, which can prevent peeling of coating during processing.

(3) Outstanding Time Sensitive

In a high-temperature working environment, compared with ordinary processing silicon steel, Laser-oriented silicon steel’s magnetic inductance is basically unchanged and will maintain high standard.

Manufacturing Process

The production of laser-oriented silicon steel begins with the rolling of silicon steel sheets, during which the grains are oriented. Afterward, a laser inscribing machine precisely etches the surface of the steel sheet according to predetermined patterns. Following the laser treatment, the sheets may undergo additional processes like annealing to relieve internal stresses and further optimize the material's magnetic properties.


In summary, laser-oriented silicon steel represents an advancement in materials technology aimed at improving the efficiency and performance of electrical devices. Its unique characteristics make it a valuable component in modern power electronics, contributing to both economic and environmental benefits.
