0.27mm high induction grain oriented electrical steel

When we refers to grain oriented electrial steel, as it has silicon content range from from 2.9% to 3.5%, so we can also call it grain oriented silicon Steel Coil. The crystal structure of the Steel Plate has a certain regularity and direction, oriented electrical steel coil is an indispensable soft magnetic material in electric power industry as it magnetic properties.

Grain oriented silicon steel is an important soft magnetic alloy, mainly used in the manufacture of large and medium-sized transformers and large motors. Oriented silicon steel because of its complex manufacturing process, strict composition control, many factors affecting performance, the core technology is confidential, its product quality is an important sign to measure the level of special steel manufacturing in a country.

The Grain oriented silicon steel due to different properties and  appliations, it can be divided into:

• Convintional or nomal gardes
• High permeability garde
• High permeability and domain refined grade

Designation method For example:  27QG095, High permeability grain oriented electrical steel with the maxiumum specific loss of 0.95 W/kg at 1.7T and 50Hz and a nominal thickness of 0.27mm shall be designation as 27QG095.

Product advantange and application:

In recent years, climate change caused by greenhouse gas emissions has gradually become a global concern, the demand for reducing use of energy are increasing sharply.  The main way to reduce loss of electric energy in the process of power transmission is use green material into transformer and motors, the garin oriented electrical as its low core loss properties, it can meet the global trends, reduce the energy use of transformer. So electrical silicon steel is an indispensable material for converting new energy sources to electric energy and affecting the energy efficiency of electrical equipment.

The grains oriented silicon steel face the same direction in rolling direction, it has excellent magnetic induction in this direction, so it is suitable for static device field. Generally, high magnetic orientation silicon steel has lower iron loss performance, so when used as transformer core It can reduce the loss during the energy conversion process.
