一种高强度导磁钢板及其生产方法
摘要：
本发明公开了一种高强度导磁钢板，主要成分为Fe，还包括C、Mn、Si、P、S、Als、Nb、Ti，按质量百分数计算，上述成分的含量为：C≤0.10、0.09≤Mn＜0.90、Si≤0.20、0.08≤P≤0.20、S≤0.012、0.015≤Als≤0.05、0.01≤Nb≤0.03、Ti≤0.003，以及不可避免的杂质。本发明还公开了该钢板的生产方法。采用上述技术方案，通过冶炼化学成分控制、恰当的工艺制定，获得了具有较高力学性能并且具备良好的直流磁性能的冷轧退火钢板。这种冷轧钢板具备高屈服强度和导磁性能，使用中能够经受大的负荷而不发生变形。
摘要（英）：

The invention discloses a high-strength magnetic-conductive steel plate. The high-strength magnetic-conductive steel plate comprises a main component Fe and also comprises C, Mn, Si, P, S, Als, Nb, Ti, and inevitable impurities, wherein contents of the C, Mn, Si, P, S, Als, Nb, Ti are shown as follows: according to mass percentage, C<=0.10, 0.09<= Mn< 0.90, Si<=0.20, 0.08<=P<=0.20, S<=0.012, 0.015<= Als<=0.05, 0.01<= Nb<=0.03, and Ti<=0.003. The invention also discloses a producing method of the steel plate. Through adoption of the technical scheme, and through chemical component control of smelting and an appropriate process formulation, the cold-rolled and annealed steel plate having high mechanical properties and having a good direct-current magnetic property is obtained. The cold rolled and annealed steel plate has high yield strength and a magnetic conductive performance, and can bear large loads without deformation when in use.
