研究了常化对CSP流程生产的wSi=1.6%的无取向电工钢组织、织构和成品磁性能的影响。结果表明,经CSP流程生产,且在相同的冷轧及退火制度下,经1 000℃×2min常化处理的wSi=1.6%的无取向电工钢热轧板,其最终退火成品的铁损P15/50比不常化试样下降了10.5%,磁感B50比不常化试样提高了2.5%;常化使wSi=1.6%的无取向电工钢成品的平均晶粒尺寸增大,成品铁损P15/50相应减小;同时,常化使wSi=1.6%的无取向电工钢成品中高斯织构的强度增加,γ纤维织构的强度减弱,这有利于成品磁感B50的提高。
The influence of normalization on the microstructure, textures and magnetic properties of the finished ws = 1.6% non-oriented electrical steel produced by CSP process was studied. The results show that the hot-rolled non-oriented electrical steel plate with wSi = 1.6%, which is produced by CSP process and normalized by 1 000 ℃ × 2min under the same cold rolling and annealing regime, / 50 decreased by 10.5% than the unnatural sample, the magnetic induction B50 increased by 2.5% than the unnatural sample; normalized the average grain size of the non-oriented electrical steel product wSi = 1.6% increase, the finished iron At the same time, the normalization makes the strength of Gaussian texture in the non-oriented electrical steel product with wSi = 1.6% increase, and the strength of the gamma fiber texture weakens, which is beneficial to the improvement of the magnetic induction B50 of the finished product.
