摘要/Abstract

摘要： 试验研究了球刻痕法对高磁感取向硅钢的铁损、矫顽力、相对磁导率、巴克豪森噪声等磁学性能的影响.研究结果表明:经过球刻痕处理后，高磁感取向硅钢的铁损明显降低，矫顽力下降，8mm球刻痕过后铁损值与矫顽力分别下降162%和147%，且铁损和矫顽力均随刻痕间距降低而减少.刻痕后的高磁感取向硅钢磁导率在高磁感应强度下明显上升，刻痕后巴克豪森噪声值明显降低，经过对比分析确定8mm为球刻痕的最佳刻痕间距.从磁畴观察、细化磁畴的原理等方面解释了细化磁畴对高磁感取向硅钢性能的影响原因.

Abstract: The effects of the ball scribing on magnetic properties of high permeability grainoriented silicon steels， including the iron loss， coercive force， relative permeability， and Barkhausen noise were investigated. The results showed that the iron loss and coercive force of the high permeability grainoriented silicon steels apparently decreased 162% and 147% respectively after 8mm ball scribing and they both decreased with the decrease of the scribing spacing at the same magnetic flux density. At high flux densities， the permeability of the high permeability grainoriented steels apparently increased， and Barkhausen noise decreased after the ball scribing. After comparison and analysis 8mm is settled as the optimum scribing spacing. The effects of the domain refinement on high permeability grainoriented silicon steels were interpreted from the static domain observation and principles of domain refinement.

Key words: ball scribing, high permeability grainoriented silicon steel, iron loss, Barkhausen noise, coercive force, permeability
