The forming characteristics of ridge buckle defects for grain-oriented silicon steel are different from others.In this paper,the effects of composition,process route,coiling tension of steel strip after decarburi-zation annealing and high temperature annealing process on theridge buckle defects for grain-oriented silicon steel were studied.The results show that the ridge buckle defects only exists on the mixed grain structure steel strip composed of abnormally large and fine grains with significant size differences in the matrix;The composition,process route,and high-temperature annealing process significantly affect the metallographic structure of the final sample,which is the main influencing factor for ridge buckle defects;The deformation caused by the difference in grain boundary quantity exceeds the critical deformation deformation of the steel strip,which is the fundamental cause of ridge buckle defects.
