Brief classification of silicon steel

GNEE Steel Oriented Silicon Steel

Silicon steel can be divided into hot-rolled silicon steel and cold-rolled silicon steel. Hot-rolled silicon steel is gradually being eliminated due to its low availability and high energy loss. Cold-rolled silicon steel has become the focus of future development due to its high technical content and low loss. Cold-rolled silicon steel is divided into: cold-rolled oriented silicon steel and cold-rolled non-oriented silicon steel.
​

The main purpose of cold-rolled grain-oriented silicon steel is for transformer manufacturing, so it is also called cold-rolled transformer silicon steel. HiB steel among grain-oriented silicon steels is called high magnetic induction cold-rolled grain-oriented silicon steel. Due to its good magnetic permeability and low loss characteristics, it is mainly used to manufacture various high-voltage transformers, choke coils and other electromagnetic components in the telecommunications and instrumentation industries.

The two most important indicators of grain-oriented silicon steel are: magnetic induction and unit loss value. The higher the magnetic induction, the stronger the magnetic permeability, the smaller the core volume, the lower the iron loss and copper loss, and the lower the total cost of material consumption. The lower the specific loss value, the better it can be used in larger transformers. Different types of oriented silicon steel can be used in transformers of different voltage levels and types due to different indicators such as magnetic induction and loss. Different types of oriented silicon steel can be used in transformers of different voltage levels and types due to different indicators such as magnetic induction and loss.

Non-oriented silicon steel is mainly used in the manufacture of generators.
High magnetic induction oriented silicon steel (HiB steel) has excellent magnetization characteristics, and the magnetic induction under standard conditions is approximately 1.92T. Ordinary oriented silicon steel is 1.82T, which can effectively reduce transformer losses. HiB steel is mainly used in high voltage transformers due to its low losses and high conductivity. my country's power grid construction will require more high-voltage transformers in the future, and more use of low-loss high-voltage transformers will also be the future trend of the transformer market.
