Silicon steel sheet inspection
Because silicon steel is an important soft magnetic alloy, and it is widely used and used in large quantities, it is necessary to detect silicon steel to ensure that the magnetic properties of silicon steel meet the requirements of the products. At present, the main reference GB/T 13789-2008/IEC 60404-3:2002 "with a single sheet tester measuring method of electrical steel sheet (strip) using Epstein methods of measurement of electrical steel sheet magnetic energy method" and GB/T 3655-2008/IEC60404-2:1996 "(with)" method of magnetic properties, and other standard silicon steel detection.
Silicon steel is a silicon iron alloy with silicon content of about 3%~5% and other major iron. Because of the structure and different purposes is divided into non oriented silicon steel and oriented silicon steel, mainly used as the core of various motors, generators, compressors, motors and transformers, is an important soft magnetic alloy, power electronic and military industry.
Domestic magnetic survey, there are few manufacturers strength. Can refer to Changsha sky measurement and Control Technology Co., Ltd., beginning in 1984, has been focused on electromagnetic measurement equipment research and development, production. The detection of steel product line complete, a test system of monolithic silicon steel (TD8500, TD8510), the measurement system can broadband AC electrical steel magnetic (TD8520, TD8530), DC characteristics of silicon steel sheet testing system (TD8570), silicon steel sheet, the online detection system (TD9100) etc..
