Title:
HIGH-MAGNETIC-INDUCTION LOW-IRON-LOSS NON-ORIENTED SILICON STEEL SHEET AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/206753
Kind Code:
A1
Abstract:
Provided are a high-magnetic-induction low-iron-loss non-oriented silicon steel sheet and a manufacturing method therefor. The chemical composition by mass percentages is: C ≤ 0.005%, Si: 0.1%-1.6%, Mn: 0.1%-0.5%, P ≤ 0.2%, S ≤ 0.004%, Al ≤ 0.003%, N ≤ 0.005%, Nb ≤ 0.004%, V ≤ 0.004% and Ti ≤ 0.003%, with the balance being Fe and inevitable impurities; and at the same time satisfies: 120 ≤ [Mn]/[S] ≤ 160, and [Nb]/93+[V]/51+[Ti]/48+[Al]/27 ≤ [C]/12+[N]/14. After casting, the cooling rate in a cool-down process of a cast blank is controlled, and a temperature controlling method is used to adjust the charging temperature of the cast blank.
