CRGO Silicon Steel

CRGO grain-oriented silicon steel refers to cold-rolled electrical steel containing 2.9%~3.5%i, and the crystal structure of the steel plate has certain rules and directions. It generally refers to a single-oriented silicon steel sheet with a Gaussian texture, that is, a silicon steel whose crystal plane is parallel to the rolling surface and whose crystal orientation is parallel to the rolling direction.

Product Introduction

Gnee Super Alloy (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of crgo silicon steel in China. If you're going to wholesale high quality crgo silicon steel made in China, welcome to get free sample from our factory. Good service and reasonable price are available.

Cold-rolled electrical steel is also called silicon steel, As the name suggests, the electrician silicon steel is made by cold rolled with the silicon content ranged from 0.8％-4.8％. General thickness below 1mm, therefore calls the thin steel.

The cold rolled oriented silicon steel is classified as the crystal grain non- oriented and the crystal grain oriented one. The crystal grain oriented cold rolling steel serves as the power transformer, large-scale generators and other equipment cores.

Application of CRGO Silicon Steel as Transformer Core

CRGO grade steel mainly finds applications as core material for power transformers and distribution transformers. This can be explained as below

High magnetic permeability leads to low excitation currents and lower inductions.
Low hysteresis and eddy current losses.
Excellent lamination factor leads to better and compact designs and hence low material required.
High knee saturation characteristics.
Very low level of magnetostriction leads to noise reduction.
Enhances ease of winding and improves productivity.

Future Scope of CRGO Silicon Steel

While there have been alternatives to the CRGO grades of steel such as nickel-iron, mu-metal, amorphous boron strip, superglass etc still CRGO steel is the superior choice in the transformer industry. Alloys like the amorphous metal Fe78-B13-Si9 has shown to have much lesser core losses when used as the core of distribution transformer as compared to the CRGO grade steel. An optimum constituent of silicon addition in steel can change the texture so as to achieve desirable magnetic properties when manufactured under controlled conditions.
