Kotuza O. Improvement of the electromagnetic method of temperature controlling by the parametric converter

The object of the research: the process of interaction of electromagnetic field with the object of control, to obtain information about the temperature of electrically conductive products. The aim of the research: to improve the electromagnetic method and devices on the basis of the use of the parametric electromagnetic transducer for non-contact temperature control on the surface and averaged over cross section of the cylindrical conductive products. Research methods and apparatus: the main theoretical positions of the work are based on the fundamental principles of electrodynamics of continuous media, the theory of electric and magnetic measurements, the theory of errors, approximate calculations, methods for calculation of electric circuits; the installation with standard equipment was used for temperature control. Theoretical and practical results: new technical decisions, based on the established methods and devices that are implemented in production, are developed. Originality: for the first time the correlation between the amplitude, phase and frequency of the parametric transducer signal and the temperature of electrically conductive products is obtained. Degree of implementation: the "SKB Ukrelektromash", Kharkiv; the "Zaporozhye NPP", Energodar; the CJSC "Lugcentrokuz", Lugansk; in the educational process at the Volodymyr Dahl East Ukrainian National University, Lugansk. The scope (sphere) of use: the obtained theoretical and practical results can be applied for temperature control in the cross section of the product during thermal processing of electrically conductive parts at machine building enterprises.
