Industrial Automatic Control Systems and Controllers Annotation << Back System for Predictive Calculation of the Residence Time of Workpieces in Heating Furnaces Fomin A.V., Gmyrya E.E. The purpose of this work is to write a functional program code that will calculate the predicted time of stay of blanks in the technological process of the heating furnace. The implemented system function by transferring the calculated data to the mathematical model of metal heating will reduce the consumption of resources necessary for the furnace operation and improve the quality of the metal leaving the furnace and entering the rolling mill. Keywords: forecasting, heating furnaces, blank heating time, quality, rolling mill, metal blank, functional program code, heating blanks before rolling, blank tracking.
