Models Between Barkhausen Noise and Coercive Force of Grain-Oriented Electrical Steel
Effect of ball scribing on relational models between coercive force and Barkhausen noise of conventional grain-oriented (CGO) and high-permeability grain-oriented (HGO) electrical steel was investigated.Models between two parameters in both CGO and HGO electrical steel were established.The results show that after ball scribing,Barkhausen noise of CGO steel increases ( 26% after 4mms scribing at 1.0T) and that of HGO electrical steel apparently decreases (17.3% with 16mms scribing at 1.0T),while coercive force of both CGO and HGO electrical steel decreases.Models between coercive force and magnetic Barkhausen noise after scribing were also constructed according to experimental data,and the experimental data curves were analyzed in the magnetizing process,which provides reference for correlation of different magnetic parameters.
