Although the manufacturing process has been well estabilished, the process is still complicated [3]. Recently, the progress in strip-casting technology [4] provides a possibility to manufacture silicon steel sheet by a simpler processing than the conventional process, because the strip casting process can supply a silicon steel strip with the sa
