Transformer silicon steel sheet: analysis of process characteristics of silicon steel with different silicon contents
The application methods of silicon steel sheets with different silicon contents in processing and application are generally as follows:
1. [Si]>2% must be subjected to electromagnetic stirring
2. When [Si]>2%, if a one-time cold rolling process is used, it must be normalized and then acid washed
3. When [Si]>2%, due to the high deformation resistance, a 20 high rolling mill is often used for cold rolling
4. When [Si]>3% or [Si] [Al] ≥ 3.5%, it must undergo secondary cold rolling, and the first cold rolling should be preheated to 100-150 ℃
