METHOD OF OBTAINING ELECTRICAL SHEET OF NON-ORIENTED CRYSTALLITE |
| 摘要 |
The invention relates to a method to produce non-grain-oriented magnetic steel sheet made of thin-slab or slab casting with low specific total loss and high polarisation and favourable mechanical properties. It is a characteristic of the invention that the steel slabs are hot rolled either directly from the casting heat or after a reheating to T>=900 ° C. and two or more metal forming passes are performed in the two-phase region austenite/ferrite in the course of finishing rolling. |
