摘要：
本发明公开了一种含硼无取向电工钢及其无头轧制的生产方法，属于钢铁冶金生产领域，其特征在于：所述其成分为C≤0.0030％，Si：0.3-1.5％，Als:0.002-0.01％，Mn：0.1-1.0％，P:0.03-0.1％，B:0.0015-0.004％，S≤0.008％，N≤0.003％，[O]≤0.003％，其余为铁和不可避免的杂质。与现有技术相比较具有磁性优良、时效小、表面质量良好的优点。
摘要（英）：

The invention discloses boron-containing non-oriented electrical steel and an endless rolling production method thereof, and belongs to the field of ferrous metallurgy production. The steel is characterized by comprising the following components of, in percentage by weight, less than or equal to 0.0030% of C, 0.3-1.5% of Si, 0.002-0.01% of Als, 0.1-1.0% of Mn, 0.03-0.1% of P, 0.0015-0.004% of B, less than or equal to 0.008% of S, less than or equal to 0.003% of N, less than or equal to 0.003% of [O] and the balance iron and inevitable impurities. Compared with the prior art, the steel has theadvantages of being excellent in magnetism, small in aging and good in surface quality.
