The project provides the creation of a diagnostic system for high-speed detection of metal products and constructions on the basis a scanning measuring instrument of coercive force (“scanning coercive meter”) which provides the diagnostic of the products made of ferromagnetic materials – the determination of the structure, hardness, stressed-strained state of the products based on the predetermined correlation dependencies between the coercive force and controllable parameters of the material. Compared with the known technical solutions the proposed complex will allow monitoring of the products at high speed, to obtain the data on the state of the material in long products, as well as the products with a developed surface. The diagnostic device is based on a well-known method of preliminary magnetization of ferromagnetic products with moving the magnetizing device and the following measurement (scan) of the parameters of the residual magnetic field over the magnetic band. So far, topography of the residual magnetic field has been surveyed over the product magnetized according to a specific technology with a moving magnet, the conditions have been determined under which it is possible to diagnose the parameters of the material, the design of the scanning transducer has been developed, the readings of which do not depend on external magnetic fields, in particular , in the fields of the Earth. The use of the “scanning coercive meter” principle would significantly enhance the range of the controlled products due to the high-performance device and obtaining continuous distribution of the defects on the surface of the metal or along the product length.
