NON-ORIENTED SILICON STEEL AND ITS MANUFACTURING METHOD |
摘要 |
The present invention provides a non-oriented silicon steel with excellent magnetic properties and a manufacturing process therefor. During the manufacturing process of the present invention, the temperature T of the molten steel of steel tapped from a converter during steelmaking and the carbon content [C] and the free oxygen content [O] comply with the following formula: 7.27x10 3 <[O][C]e( -5000/T ) ‰¤2.99x10 4 , and the final annealing step uses tension annealing at a low temperature for a short time. A non-oriented silicon steel with a low iron loss, and excellent anisotropy of iron loss can be obtained by means of the manufacturing process of the present invention. |
