In order to online control air-mist cooling device,an air-mist cooling control model and a set of online control system have been developed for an air-mist cooling device in a heavy plate plant. With the analysis of the cooling process and the investigation of the boundary conditions,the cooling model has been built. Based on the production process of air-mist cooling and the feature of air-mist cooling device,a set of automatic control system has been built. The model and the system have been applied to a heavy plate plant,the results show that the need of online automatic control is satisfied, and the cooling rate and the temperature precision expected are reached.
