Cold Rolled Grain-Oriented Electrical Steel/ Silicon Steel/CRGO

Cold Rolled Grain-Oriented Electrical Steel/Cold Rolled Grain-Oriented Silicon Steel/CRGO has its easy magnetization grain direction aligned along the rolling direction, which gives it excellent properties such as high magnetic flux density, low core loss, and low magnetostriction. It is widely used in industries such as transformers, reactors, mutual inductors, and electric motors. Additionally, by refining the magnetic domain through technical processing, it is possible to achieve even lower core loss performance.

  • Q&A

    Cold Rolled Grain-Oriented Electrical Steel/Cold Rolled Grain-Oriented Silicon Steel/CRGO refers to cold-rolled electrical steel containing 2.9% to 3.5% silicon, with a certain regularity and direction in the crystal structure of the steel plate. It generally refers to single-oriented silicon steel sheets with a high-Goss texture, where the grain surface is parallel to the rolling surface and the crystallographic direction is parallel to the rolling direction. There is also cold-rolled dual-oriented (cubic texture) silicon steel.

    The production of Cold Rolled Grain-Oriented Electrical Steel/Cold Rolled Grain-Oriented Silicon Steel/CRGO with a Goss texture relies on secondary recrystallization. To achieve secondary recrystallization, it is usually necessary to add normal grain growth inhibitors, such as MnS, to the alloy. These inhibitors must be able to disperse in the alloy matrix in an impurity form and effectively prevent normal grain growth during the secondary recrystallization process. At the same time, they must be easy to eliminate during the final high-temperature annealing to avoid deteriorating the magnetic properties of the product. In secondary recrystallization, the orientation nuclei for secondary grain growth primarily depend on appropriate cold rolling processes and recrystallization annealing. Since phase transformation can disrupt grain orientation, maintaining a single phase during the heat treatment process is critical.

    Cold Rolled Grain-Oriented Electrical Steel/Cold Rolled Grain-Oriented Silicon Steel/CRGO has excellent electromagnetic properties, which are attributed to state-of-the-art equipment, advanced manufacturing processes, and strict management. At the same time, the processing performance of cold-rolled oriented electrical steel is also outstanding. Its high-precision dimensions and excellent mechanical properties make it more convenient for users during slitting, shearing, and stacking. The dimensional accuracy is exceptional, ensuring good flatness, smooth surface, uniform thickness, and minimal variation across sheets, resulting in a high stacking coefficient. Additionally, cold-rolled oriented electrical steel has excellent surface coating properties, with a uniform coating and strong adhesion, preventing coating detachment during processing. It also possesses good interlaminar insulation performance. The width range is from 750 to 1270mm, allowing users to choose according to their needs, further improving material utilization.
