Cold Rolled Non Oriented Silicon Steel

The non-oriented silicon steel features even magnetic properties in the rolling direction and in other directions. They are widely used for iron core materials of rotating machines ranging from large-size power generators to small-size precision electric motors. They are also desirable for iron core of small-size power transformers.

CRNGO Steel
Cold-rolled non-oriented silicon steel (CRNGO) is another type of electrical steel used in the construction of transformer cores, electric motors, and other electromagnetic devices. Unlike cold-rolled grain-oriented silicon steel (CRGO), which has a preferred grain orientation, CRNGO steel has a non-oriented or random grain structure.

  1. Random Grain Structure: In CRNGO steel, the grains are not intentionally oriented during the cold-rolling process. This results in a more isotropic material with magnetic properties that are relatively consistent in all directions.

  2. Higher Core Losses: Compared to CRGO steel, CRNGO steel generally has higher core losses. Core losses include hysteresis and eddy current losses, which contribute to energy dissipation in the form of heat during the operation of electromagnetic devices.

  3. Applications: CRNGO steel is often used in applications where the direction of the magnetic field varies, such as in electric motors, generators, and certain types of transformers. It is suitable for applications where the primary concern may be cost or where the specific magnetic characteristics of the material are more important than achieving the lowest possible core losses.
