Longbank Non-Grain Oriented Electrical Steel Types

Longbank Non-Grain Oriented Electrical Steel Types

The non-grain oriented electrical steel is manufactured in 2 types such as:

Fully-processed Non-Grain Oriented Electrical Steel – The fully-processed non-grain oriented electrical steels have magnetic properties that are fully developed through the mill. To achieve the ideal magnetic performance and properties of fully processed non-grain oriented electrical steels, they require SRA or Stress Relief Anneal. The fully-processed non-grain oriented electrical steels are ideal for magnetic circuits in electrical system housing, transformers, and motors.

Semi-Processed Non-Grain Oriented Electrical Steel – The semi-processed non-grain oriented electrical steel needs a final heat treatment. The heat treatment is also known as QDA or Quality Development Anneal. After the final cold rolling process, they are annealed at low temperatures. The semi-processed non-grain oriented electrical steel does not usually need organic coatings. They also have better punchability than the fully-processed type. Moreover, they are perfect to use for small power transformers, stators, small rotors, etc.

Longbank Non-Grain Oriented Electrical Steel Production

When manufacturing non-grain oriented electrical steel, Longbank uses advanced technologies, equipment, and cutting-edge facilities to ensure quality and meet customers’ expectations. Every process of producing is automatically controlled. Some of the processes include:

Hot rolling – The electrical steels are continuously cast or molten in the oxygen furnaces. Then, they are hot rolled and pass through the process line of annealing.

Preliminary Annealing – In the preliminary annealing, there is a hydrochloric acid cleaning and scale breaker that removes the scales and dirt on the surface of the steel.

Cold Rolling – In this process, the steel’s thickness is reduced and adjusted based on the customers’ specifications. The cold rolling process is also done to get the exact magnetic properties.

Annealing & Insulation Coating – In this process, the carbon content of the steel will be reduced by the decarburizing anneal. Then, the non-grain oriented electrical steel is recrystallized through heat treatment. Contaminants such as sulfur will also be removed in the annealing process. Then, there are different types of insulation coating that will be applied depending on the customers’ requirements and applications.
