【摘要】：激光刻痕是一種降低取向硅鋼片鐵損的有效方法。選取激光功率、掃描速度、激光頻率、刻痕間距作為工藝變量,對(duì)取向硅鋼片進(jìn)行刻痕實(shí)驗(yàn),并利用磁性能測(cè)試系統(tǒng)和磁疇觀測(cè)儀研究了不同工藝參數(shù)對(duì)激光刻痕后取向硅鋼鐵損和磁疇的改善效果。結(jié)果表明,取向硅鋼片的平均鐵損降低率隨激光功率和刻痕間距增大而先增大后減小,隨激光頻率和掃描速度增大而減小。經(jīng)不同工藝參數(shù)刻痕后,硅鋼片的磁疇寬度均有所減小,且磁疇寬度的變化規(guī)律與鐵損降低率的變化規(guī)律相吻合。優(yōu)化了取向硅鋼片的激光刻痕工藝參數(shù),利用此工藝刻痕后,取向硅鋼片的平均鐵損降低率達(dá)8%。
[Abstract]:Laser indentation is an effective method to reduce the iron loss of oriented silicon steel sheet. Laser power, scanning speed, laser frequency and indentation distance are selected as process variables. The improvement effects of different process parameters on the iron loss and magnetic domain of oriented silicon steel after laser indentation were studied by using the magnetic property test system and the magnetic domain observation instrument. The results show that the reduction rate of the average iron loss of the oriented silicon steel increases firstly and then decreases with the increase of laser power and the distance between the marks, and decreases with the increase of laser frequency and scanning speed. After different process parameters, the magnetic domain width of silicon steel sheet is decreased, and the variation of magnetic domain width is consistent with the change of iron loss reduction rate. The laser indentation parameters of the oriented silicon steel sheet were optimized. The average iron loss reduction rate of the oriented silicon steel sheet was up to 8 after the process was used.
