The difference between electrical steel and non oriented electrical steel
1. hot rolled silicon steel plate (without orientation)2. hot rolled high silicon steel (hot-rolled transformer steel)3. cold rolled electrical steel sheet: non oriented electrical steel (cold rolled motor steel)4. silicon steel5. oriented silicon steel (cold rolled transformer steel)
Electrical steel has hundreds of years of history, including electrical steel and electrical steel Si<0.5% Si 0.5~6.5% content of silicon steel two categories, mainly used for all kinds of motor, transformer and ballast iron core, is an important soft magnetic alloy electric power, electronic industry and military. Electrical steel is the most important metal functional material in the use of magnetic materials. Electrical steel, especially the manufacturing process oriented silicon steel and complex equipments, composition control, manufacturing process, and the factors affecting the performance, so often the product quality oriented silicon steel is seen as an important symbol to measure a country special steel manufacturing technology, and special steel "art" reputation.
Electric steel, also called silicon steel sheet, is an important soft magnetic alloy for electric, electronic and military industries. It is also the largest metal functional material. It is mainly used as the core of various motors, generators and transformers. Its production process is complex, manufacturing technology is strict, and foreign production techniques are protected in patent form, regarded as the life of an enterprise. The manufacturing technology and product quality of the electric steel plate is one of the important symbols to measure the development of a special steel production and the development of science and technology in a country. At present, the number of China's cold rolled electric steel quality, specification grade, energy (electricity) can not meet the needs of the industrial development in the production technology and equipment, compared with the Japanese management and scientific research, there is a big gap.
