Abstract :
Effect of skin-pass rolling direction on magnetic properties and directionality in semiprocessed nonoriented electrical steel sheets produced by skin-pass rolling process was studied. Skin-pass rolling direction affects greatly magnetic properties and directionality. By the control of skin-pass rolling direction, the value of B50 in the required directions such as 0°, 90° and circumferential direction can be adjusted and the value of B50 is higher than that of the usual skin-pass rolling direction of 0°. The textures of the steel sheets developed after batch annealing varied with the skin-pass rolling directions and this result indicates that the residual strain energy by skin-pass rolling varies with skin-pass rolling directions
