CRGO is the abbreviation for Cold Rolled Grain Oriented Steel, which is used in particular to laminate any heavy transformer as a core. CRGO steel has exceptionally high mechanical elasticity and magnetic properties in the rolling direction. These crystals are often arranged by cold rolling at room temperature to coordinate the direction of grain formation in a specific direction. Since the magnetic properties during cold rolling depend on individual micro-crystals and direction of growth orientation.

Cold-rolled non-grain-oriented steel is often abbreviated to CRNGO. Grain-oriented electrical steel usually has a silicon level of 3% (Si:11Fe). It is processed in such a way that the optimal properties are developed in the rolling direction, due to a tight control (proposed by Norman P.

Grain Oriented Electrical Steel

Hot rolled silicon steel core

Switching over further to a hot-rolled silicon steel core gave a substantial reduction in core losses to 2 watts/kg at a flux density of 1.5 Teslas. The core material will have more permeability when magnetized in a rolling direction and thus reduces the core losses.

Cold-rolled grain-oriented silicon steel core

They are cold-rolled steels, as the name itself suggests, which are commonly used for the most effective material at the core. At their peak magnetic flux density of 1.9 teslas, they had very high core losses of 0.7 to 0.9 watts per kg when cold-rolled in grain-oriented directions.
