Control Model of Accelerated Cooling for On-Line High-Density Pipe Laminar Flow in Plate Mill

A mathematic control model used in the accelerated cooling process is presented according to the characteristic of the first set of high-denseness pipe laminar flow accelerated cooling device in China which is built in the Heavy Plate Mill of Anshan Iron and Steel Co. The model consists of the cooling process setting model, the temperature forecast model and the temperature modifying and adapting model. A satisfactory precision has been obtained since it was used.
