Customized CRNGO Steel Electrical Silicon Transformer Steel Sheet
The relationship between non-oriented silicon steel sheet and oriented silicon steel sheet:
1. Both are cold-rolled silicon steel, but the silicon content is different. The silicon content of cold-rolled non-oriented silicon steel sheet is 0.5%-3.0%, and the silicon content of cold-rolled oriented silicon steel sheet is above 3.0%.
2. Differences in production process and performance: non-oriented silicon steel sheet has relatively lower technological requirements than oriented silicon steel sheet.
3. Performance and use: Due to the different performance characteristics of the two, there are differences in the direction of use. The most important use of cold-rolled non-oriented silicon steel sheet is for the manufacture of generators, so it is also called cold-rolled motor silicon steel. The main purpose of cold-rolled oriented silicon steel strip is for transformer manufacturing, so it is also called cold-rolled transformer silicon steel.
Non-Oriented Electrical Steel is manufactured as to render magnetic properties almost uniform in any direction of the coil. Used mainly for medium and large rotating machines, and small transformers.
●Exhibits almost uniform and excellent magnetic properties in all directions of a steel sheet.
●Typical applications: motors, generators, audio transformers, reactors, magnet switches, ballasts, magnetic fields, and electromagnets for accelerators
