Steel plate accelerated cooling control level is directly related to the shape of steel plate and the properties of the product, and with the production of the steel of high grade, high added value, such as high strength steel, the level set higher requirements on accelerated cooling automatic control. The invention relates to an accelerated cooling process control system and a control method, comprising a data acquisition device, a data pre calculation module, an online calculation module and a post calculation module. It will control the amount of each decoupling preset, considering the disturbance factors of cooling plate entrance, on-line dynamic adjustment of cooling setting, real-time accurate determination of each control volume cooling section, to meet the requirements of production control cooling plate. The utility model is suitable for popularization and application in the thick plate cooling line under various requirements. By controlling the cooling and controlling of the metal plate, the investment of the alloy is greatly reduced, and the post-processing process is saved so as to save the cost and improve the efficiency.
