Electrical Steel

This mill provides the internal energy needed for efficient grain growth by rolling steel plates up to the target gauge. This minimizes eddy current loss while in use after the manufacturing of iron core.

Types and Uses

Grain-Oriented Electrical Steel

The easy magnetization direction of grains is parallel to the rolling direction. This type of steel has superior magnetic characteristics in the rolling direction, and is used in the manufacturing of large, medium and small-sized transformers, distribution transformers and reactors.

Non-Oriented Electrical Steel

This steel with uniform magnetic characteristics in rolling and in other directions is widely used in the iron core materials or rotary machines form large transformers to small electric precision motors. It also has good characteristics for use in small transformers.
