一种变压器用冷轧取向电工钢及其生产方法
摘要：
本发明涉及一种变压器用冷轧无取向电工钢及其生产方法，其原料组分及百分含量为：C0.02～0.05％、Si3.0～3.3％、Mn0.10～0.30％、P≤0.02％、Als 0.01～0.04％、Cu0.04～0.06％、S0.005～0.015％、N0.005～0.015％、Ti≤0.004％，其余为Fe及不可避免的杂质；生产方法步骤包括热轧、冷轧、退火等，本发明采用了常规热轧工艺，利用Cu2S﹢MnS做为抑制剂而生产出轧制方向磁性能优良的电工钢板，电工钢成品轧制方向的磁性能优异，铁损低、磁感高，且磁性能波动小。
摘要（英）：

The invention relates to cold-rolled oriented electrical steel for a transformer and a production method of the cold-rolled oriented electrical steel. The cold-rolled oriented electrical steel comprises the components as follows: 0.02-0.05% of C, 3.0-3.3% of Si, 0.10-0.30% of Mn, less than or equal to 0.02% of P, 0.01-0.04% of Als, 0.04-0.06% of Cu, 0.005-0.015% of S, 0.005-0.015% of N, less than or equal to 0.004% of Ti, and the balance Fe and unavoidable impurities. The production method comprises the steps of hot rolling, cold rolling and annealing. By adopting the conventional hot rolling technology, Cu2S+MnS acts as an inhibitor, an electrical steel plate having excellent rolling orientation and magnetic performances is produced, and the finished oriented electrical steel is outstanding in magnetic performance, low in iron loss, high in magnetic induction, and small in magnetic performance fluctuation.
