Система автоматичного контролю температури для електроконтактного відпалу дроту

Abstract

Currently, the issues of improving the quality of the welding wire in the production process are topical. The advantage of using direct electrocontact heating is based on the possibility of constructing and implementing an automatic temperature control system. The control system is made with the use of the PID regulator, the power regulator, the primary pyrometric converter, the secondary converter, the current source, which makes it possible to set the appropriate parameters by the regulator to ensure the stability of the operating mode with automatic temperature control with electrocontact heating of the wire. It has been experimentally established that with the application of annealing temperature control system by controlling the temperature of the heating pyrometer, the control error did not exceed 1.3%. The tempered annealing temperature in a given range ensured the stability of the physical-mechanical characteristics of the wire. The presented solutions for the implementation of this system have been characterized by convenience of operation, reliability and quality assurance of the technological process. The further direction of research is to analyze the need to use a controlled cooling process to obtain the required mechanical parameters of annealed wire.
