Avaliação das principais malhas de controle de um forno de reaquecimento de placas do tipo Walking Beam por meio de simulações computacionais

Abstract

In the steel industry, reheating furnaces play a fundamental role. This equipment is essential for reheating the steel to give it the properties required for the process. However, it is important to note that these furnaces are associated with high energy consumption, resulting in high CO₂ emissions. The steel industry alone is responsible for approximately 7% of global CO₂ emissions. For this reason, it is essential that engineers seek more efficient and accurate control of this equipment so that these improvements translate into reductions in pollutant emissions. In this context, the purpose of this work is to apply control strategies to analyze system performance. This study presents a literature review of important topics in control systems and, in addition, simulates the loops of the proposed furnace using Matlab, including the design of the controllers, the simulations and the results obtained from the tuned loops.
