CN103388106A 一种高磁感低铁损无取向电工钢板及其制造方法 无效 - 撤回

一种高磁感低铁损无取向电工钢板及其制造方法
摘要：
本发明公开了一种高磁感、低铁损无取向电工钢板及其制造方法，其化学成分的重量百分比为：C≤0.004％、Si：0.1～1.6％、Mn：0.02～1.0％、S≤0.003％、Al：0.1～0.6％、N≤0.003％、Ti≤0.0015％，且满足Si+A1∶0.2～2.0％，Mn、Si、Al满足Mn＝k2×Si+k3×Al+a，k2＝0.08～0.11，k3＝0.17～0.38，a为常数，其余为Fe和不可避免的杂质；该高磁感、低铁损无取向电工钢板的磁感B50为1.70-1.78T，铁损P15/50为3.59-5.5W/kg，表面状态良好，制造成本相对低廉，且不经过常化或罩式炉中间退火，无瓦楞状缺陷，具有高磁感、低铁损，比同牌号常规无取向电工钢板产品磁感B50高0.02T，铁损P15/50低0.2W/kg。
摘要（英）：

The invention discloses a non-oriented electrical steel plate with high magnetic induction and low iron loss, and a manufacturing method thereof, wherein the weight percentage of the chemical components of the steel plate is as follows: less than or equal to 0.004 % of C, 0.1-1.6% of Si, 0.02-1.0% of Mn, less than or equal to 0.003% of S, 0.1-0.6% of Al, less than or equal to 0.003% of N and less than or equal to 0.0015% of Ti, wherein Si+Al is between 0.2-2.0%, and Mn, Si and Al satisfies the following formula: Mn=K2*Si+K3*Al+a, k2=0.08-0.11, k3=0.17-0.38; a is a constant and the balance is Fe and unavoidable impurities. The non-oriented electrical steel plate with high magnetic induction and low iron loss has 1.70-1.78T of magnetic induction B50 and 3.59-5.5W/kg of iron loss P15/50, has good surface state and is relatively low in manufacture cost without intermediate normalizing or batch annealing, has high magnetic induction, low iron loss and no corrugated defect, and has a magnetic induction B50 0.02T higher and an iron loss P15/50 0.2W/kg lower than those of a normal non-oriented electrical steel plate with same license number.
