Electrical Steel Coil Series
Silicon steel coil has the highest saturation magnetic induction value. This product is easy to mass-produce and cost-effective. It is also the most used material in the power electronics industry.
Electrical Steel Coil By Types (5)
-
Non-oriented fully processed electrical steel coils are commonly used in generators, electric motors, transformers, and alternators due to their high magnetic permeability. It has also high magnetization saturation and low core loss.
-
Largely non-silicon alloyed steel. After the final cold rolling, this product is annealed at low temperatures. It is ideal core material for stators, small rotors, and small power transformers.
-
Grain-oriented electrical steel coil delivers low energy loss, high permeability and has strong crystallographic properties. These are mostly used for non-rotating applications.
-
Non grain-oriented electrical steel coil has excellent magnetic performance. It is highly dependent on the silicon content.
-
Cold-rolled steel coils have a nice finished surface. It is produced by a hot-rolled steel process and has a higher carbon content. Longbank custom your specific requirements.

Electrical Steel Coil Productions
Longbank uses advanced manufacturing and coating lines to produced high-grade electrical coil sheets. Electrical steel sheets are normally melted in oxygen furnaces. Afterward, they are hot rolled as they move through descaling and annealing machines. This process removed dirt and scale from the surface. Then, they go through cold reduction. This method reduced and rectify steel thickness to meet your requirements.
Next, we use Decarburising anneal process line for reducing steel carbon content. The steel coil is heated in a mixture of nitrogen, hydrogen, and water vapor. Below are the machines we use:
- Pickling And Tandem Cold-Rolling Mill.
- Descaling Process Line.
- Decarburising Anneal Line.
- Annealing And Coating Line.
