AB - One of the main factors having a significant effect on fuel and energy saving  in the production of rolled ferrous metals is matching the operation of the  continuous casting machines (CCM) with that of the reheating furnaces so  called “continuous technologies” in the form of “direct rolling” or “hot  charging”. In order to investigate the heat exchange processes, the  opportunities for enhancing the energy efficiency and determining the optimal  parameters of the flat product production process in ferrous metallurgy, some  mathematical models of metal solidification and cooling in a continuous steel  casting machine were determined as well as a mathematical model of metal  heating in the reheating furnaces. For efficient implementation of such  technologies one common algorithm was built on the basis of the individual  mathematical models, representing the continuous casting - rolling mill  complex control technology, dynamically matching the operation of the  individual units to the actual production conditions in on-line mode. The  developed algorithm can be used as part of a system for analyzing the thermal  condition of the blocks at any single moment for the purpose of optimization  of the units’ operation within the whole technological process. As a  conclusion, considering the original developed algorithm, a 21-51% energy  saving was noticed.
