UTILIZATION MATHEMATICAL AND PHYSICAL MODELS DERIVED THEREFROM REAL-TIME MODELS FOR THE OPTIMIZATION OF HEATING PROCESSES

摘要

Heating of materials is energy and costly operations. On those reasons optimization is highly desirable. One of the possible solutions to optimize healing in real time is to use a large number of fast simulations on the basis of them the optimization algorithms have chosen the most appropriate option of the heating control. This solution implies the use of extremely fast but sufficiently accurate simplified mathematical models of heating, the structure and parameters of them are defined based on accurate modelling using computationally intensive but slower classical mathematical-physical models. Based on the operating data of the reheating furnace was build an accurate model of heating. Using the simplified model simulation of heating was done with different heating conditions with downtime during heating. Proposed algorithms including the simulations show that the proposed strategy leads to verifiable savings during heating.
