Crgo silicon steel sheet.
Goss the early inventor of the cold rolled grain oriented silicon steel or crgo steel manufacturing process in 1933 gave the idea in his own words i have experimental evidence which leads me to believe that there is an apparent relation between the grain size and ductility of a specimen and its magnetic properties.
Grain oriented electrical steel is an essential material in the manufacture of energy efficient transformers and large high performance generators.
Sheet steel obtained as a result of such a process is called cold rolled grain oriented silicon steel more commonly called crgo.
Shanghai metal corporation is a trusted grain oriented silicon steel crgo cold rolled grain oriented steel supplier in china we have extensive inventory of grain oriented silicon steel crgo cold rolled grain oriented steel and other metals in various alloys and tempers.
Crgo silicon steel is widely used for making transformer cores.
The magnetizing current required by transformers using crgo steel is low.
