Abstract
Hot strip cooling temperature and its cooling rate is get by strip cooling system and coiling temperature of hot rolled strip is an important parameter on its performance index. A clew regarded as the laminar cooling control system is controlled by general linear analytical model. Under detailed analysis of its control system structure, basic theory, analytical method, system design and control method, the structure of the temperature control system is characterized by feed-forward control as the main combined with feed-backward control as the assistant, the configuration software for laminar cooling process is constructed, the mathematics model is present, the characteristic of emerging fieldbus control system is analyzed, and the configuration of fieldbus is brought forward and sketch of distributed structure of laminar cooling control system in a hot rolling mill based on fieldbus and intelligent sensor is presented.
