Product Details

Silicon steel is a silicon iron alloy with a silicon content of 3%~ 5%.Divided into oriented silicon steel and non-oriented silicon steel, it is an important soft magnetic alloy which is indispensable for power, electron and military industry.Was once known as "the arts and crafts of steel products"

Silicon steel classification

Hot rolled silicon steel sheet

Hot rolled silicon steel sheet is Fe - Si alloy with open hearth and electric furnace melting, repeated hot rolled into sheet, finally, in 800-850 ℃ after annealing.Hot rolled silicon steel sheet is mainly used for the manufacture of generator, so it is also called hot rolled motor silicon steel sheet, but its utilization is low and the energy loss is large. In recent years, relevant departments have forced the elimination of the demand.

Cold-rolled non-oriented silicon steel sheet

The main purpose of cold-rolled non-oriented silicon steel is used for generator manufacturing, so it is also called cold rolled motor silicon steel.It has a silicon content of 0.5% to 3.0%, and the supply state is 0.35mm and 0.5mm thick steel strip after cold rolling to finished product thickness.The Bs of cold-rolled non-oriented silicon steel is higher than the oriented silicon steel.Compared with hot rolled silicon steel, its thickness is uniform, its dimension is high and its surface is smooth and smooth, thus the filling coefficient and magnetic energy of the material are improved.

Cold-rolled oriented silicon steel sheet

The most important purpose of cold-rolled oriented silicon steel belt is for transformer manufacturing, so it is also called cold rolled transformer silicon steel.Compared with the cold-rolled non-oriented silicon steel, the magnetic orientation of the oriented silicon steel is strong.It has superior permeability and low loss characteristics in the direction of easy magnetization.The iron loss of the orientation steel strip in the direction of rolling is only one third of the horizontal one, and the ratio of the magnetic conductivity is 6:1, and the iron loss is about 1/2 of the hot-rolled belt, and the magnetic conductivity is 2.5 times that of the latter.

The grain-oriented silicon steel is a kind of electrical steel with its easy magnetization direction parallel to the rolling direction and a silicon content of around 3%. The grain-oriented silicon steel can be divided into two major categories including common grain-oriented silicon steel and high magnetic induction grain-oriented silicon steel. It is mostly applicable to the field of power transmission (such as transformers) and is an important functional metal material in the electrical power, electronic and military industries.
