20、 clear with prolonging annealing time, but it became more uniformity and iron loss reduce. 試驗結(jié)果分析 Result and Analysis 討論分析 Discuss and analysis 1、硅含量越高成品鐵損越低The higher silicon the lower iron loss電工鋼的鐵損（PT）主要包括磁滯損耗（Ph）、渦流損耗（Pe）和反常損耗（Pa）三部分，影響電工鋼鐵損的因素多而且復(fù)雜，其中一些影響因素對三種損耗具有完全相反的影響，因此電工鋼的鐵損性能最終是三者的綜合體現(xiàn)。隨

21、硅含量的增加，電阻率明顯增加，渦流損耗降低，成品晶粒尺寸增加，晶界數(shù)量減少，磁滯損耗也降低,因此總的鐵損也降低。Electrical steel iron loss ( Pt ) include hysteresis loss(Ph), eddy current loss (Pe) and abnormal loss (Pa) three parts, influence factors is complex, some influence factors has opposite effect, so the iron loss of electrical steel is a compre

22、hensive value of the three. Increase silicon content, resistivity increased obviously , eddy current loss reduced, the grain size increases, the number of grain boundaries decreased, hysteresis loss also reduced, so the total iron loss also reduced.2、退火溫度升高，成品鐵損降低Increasing annealing temperature ,th

23、e finished product iron loss reduced.討論分析晶粒是影響鐵損的重要因素，因為晶界處的原子排列混亂，存在許多空位和位錯等缺陷，點陣排列和應(yīng)力狀態(tài)畸變，阻礙磁疇移動。因此退火溫度升高，晶粒尺寸增加，晶界長度減小，磁滯損耗減小，渦流損耗增加。但增加的渦流損耗遠小于磁滯損耗的減少量，因此總的鐵損是降低的。當(dāng)減少的磁滯損耗與增加的渦流損耗差值最大時，成品的鐵損會達到最小值，而該晶粒尺寸為最佳尺寸。Grain is an important factor influence of iron loss, because the atoms are confusion ar

24、range in grain boundary, there are many vacancy and dislocation and other defects, dot matrix arrangement and stress state distortion, block magnetic move, grain size increased, grain boundary length decrease, the hysteresis loss decreases, eddy current losses increase. But increased of the eddy cur

25、rent loss is far less than the decreased of the hysteresis loss, so the total iron is decrease. The iron loss of finished product will reach the minimum value when the decrease hysteresis losses and increase the eddy current loss difference value is the biggest, then the grain size is the best size. 結(jié)論Conclusion 1、在一定范圍內(nèi)升高退火溫度，晶粒尺寸增加，鐵損降低，繼續(xù)升高退火溫度，鐵損變化不明顯。the grain size increased and t
