1、硅含量越高成品鐵損越低Thehighersiliconthelowerironloss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〕三局部，影響電工鋼鐵損的因素多而且復雜，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表達。隨硅含量的增加，電阻率明顯增加，渦流損耗降低，成品晶粒尺寸增加，晶界數量減少，磁滯損耗也降低,因此總的鐵損也降低。Electricalsteelironloss(Pt)includehysteresisloss(Ph),eddycurrentloss(Pe)andabnormalloss(Pa)threeparts,influencefactorsiscomplex,someinfluencefactorshasoppositeeffect,sotheironlossofelectricalsteelisacomprehensivevalueofthethree.Increasesiliconcontent,resistivityincreasedobviously,eddycurrentlossreduced,thegrainsizeincreases,thenumberofgrainboundariesdecreased,hysteresislossalsoreduced,sothetotalironlossalsoreduced.2、退火溫度升高，成品鐵損降低Increasingannealingtemperature,thefinishedproductironlossreduced.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，點陣排列和應力狀態畸變，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，成品的鐵損會到達最小值，而該晶粒尺寸為最正確尺寸。Grainisanimportantfactorinfluenceofironloss,becausetheatomsareconfusionarrangeingrainboundary,therearemanyvacancyanddislocationandotherdefects,dotmatrixarrangementandstressstatedistortion,blockmagneticmove,grainsizeincreased,grainboundarylengthdecrease,thehysteresislossdecreases,eddycurrentlossesincrease.Butincreasedoftheeddycurrentlossisfarlessthanthedecreasedofthehysteresisloss,sothetotalironisdecrease.Theironlossoffinishedproductwillreachtheminimumvaluewhenthedecreasehysteresislossesandincreasetheeddycurrentlossdifferencevalueisthebiggest,thenthegrainsizeisthebestsize.結論
