Orientation distinguishing of cold-rolled silicon steel sheet

The cold-rolled silicon steel sheet is an important kind of electrical material including orientated and non-orientated sheet.About 1 million tons of silicon sheets are imported in China every year.In order to solve the problem that orientated and non-orientated cold-rolled silicon steel sheets are confused during the entry inspection,different grades of orientated and non-orientated cold-rolled silicon steel sheets from different countries are selected.Relative magnetic properties,mechanical properties,specifications and coating properties are studied in this paper to distinguish orientation of commodities easily and practicably.
