Frequently Asked Questions About Silicon Steel China Factories
What is silicon steel and what are its main applications?
Silicon steel, also known as electrical steel, is a type of steel alloy that contains silicon. It is widely used in electrical applications such as transformers, generators, motors, and inductors due to its low power loss per cycle, low core loss, and high permeability. These properties make it ideal for efficient energy transmission and storage.
How did silicon steel production start in China?
The production of silicon steel in China began in 1954 when Taiyuan Iron & Steel (Group) Co., Ltd. (TISCO) started producing hot-rolled silicon steel. Later, in 1979, WISCO introduced technologies from Nippon Steel Corporation to produce cold-rolled non-oriented silicon steel, marking a significant milestone in China’s silicon steel production.
What are the key technologies and equipment involved in producing high-grade silicon steel in China?
Producing high-grade silicon steel involves advanced technologies and equipment. Key processes include annealing and pickling lines (APL), decarburizing and coating lines (DCL), and flattening and coating lines (FCL). These lines ensure the steel meets stringent thermal process requirements, resulting in low power loss and high permeability. Companies like Baosteel and TISCO have developed and implemented these technologies to enhance their production capabilities.
