Document Type and Number:

WIPO Patent Application WO/2019/105041

Kind Code:

A1

Abstract:

Disclosed are a non-oriented electrical steel sheet with excellent magnetism and a manufacturing method therefor, wherein the mass percentage of the chemical components thereof are: C: 0-0.05%; Si: 2.1-3.2％，Mn: 0.2-1.0％, P: 0-0.2％, Al: 0.2-1.6％, N: 0-0.005％, Ti: 0-0.005%, Cu: 0-0.2%, and the balance of Fe and inevitable impurities; and at the same time, (the S content for forming MnS + the S content for forming Cu xS) / the S content in the steel is required to be less than or equal to 0.2. The process for manufacturing the non-oriented electrical steel sheet of the present invention is simple and convenient, the chemical components of the steel are easy to control, the manufacturing process is stable, and the technical requirements are easy to realize.
