ON AUTOMATIC STABILIZATION OF THE WORKING SPACE TEMPERATURE OF HEATING FURNACES

Abstract

Abstract. Introduction. In the context of increasing requirements for the quality and efficiency of the metal heating process before rolling, the task of creating and improving the algorithmic support of au-tomated process control systems (APCS) for reheating furnaces, including their local subsystems, is quite relevant. Purpose of the study. To study the dependence of the transmission coefficient of reheating fur-naces of the heating process. To develop algorithmic support for a software and hardware automatic control sys-tem (ACS) that ensures an acceptable quality of stabilization of the working space temperature. Materials and Methods. An analysis of the literature data on the problem under consideration was carried out and so-lution options proposed in the literature were considered. Results. Theoretical calculations are presented that explain the patterns of change in the transmission coefficient along the “fuel consumption – working space temperature” channel on the heating process characteristics, observed under operating conditions. Various options for representing the dependence of the transmission coefficient on the influencing variables were obtained and the necessary computational study was carried out. The structure of the most preferable op-tion for implementing the adaptive ACS is proposed. Conclusion. The results of the work can be used in the development and improvement of algorithmic support for automated process control systems for heating furnaces.
