Cold-rolled oriented silicon steel
Cold-rolled oriented silicon steel, also known as cold-rolled transformer steel, is an important ferrosilicon alloy used in transformer (iron core) manufacturing industry. Its production process is complex, manufacturing technology is strict, mainly divided into ordinary oriented silicon steel (CGO) and high magnetic induction oriented silicon steel (HiB). Oriented silicon steel was first discovered by N.P. Gauss in the United States in 1930.
