Control And Optimization Of Walking-Beam Reheating Furnace

Reheating furnace is one of the most important facilities in steel rolling, and consumes great amount of energy. So it is essential to improve heating efficiency and reduce energy consumption for steel industry. Modern rolling mills are developing to be continuous, large-scale, fast produce, high quality, which deliver a higher demand for the research of reheating furnace modeling and optimal control. However, the advanced computer control theory of reheating furnace is still far from mature, and there is little successful application example. This is because that reheating furnace is a typical complicated industry system. Complex thermodynamic, chemical and physical change makes it a system with multi-variable, time variety, non-linearity, strong coupling, pure time delay and a lot of disturbance factor.The aim of reheating furnace control is to set optimal...
