Abstract

We have developed an eddy current based technique to achieve an online precise measurement of the surface silicon content of content graded 6.5% silicon steel sheets. The technique utilizes minute direct magnetization for permeability control of the surface to suppress the permeability change due to variations in the surface silicon content.
