中厚板轧后高密度管层流快冷控制模型

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

摘要: 根据鞍钢厚板厂投产的国内第一套中厚板轧后高密度管层流控冷装置的特点,结合理论分析,建立了一套适用于中厚板轧后快冷的控制用数学模型.该模型由层流冷却预设定冷却模式、各预设定冷却模式下终冷返红温度预报模型、终冷返红温度修正模型、自学习模型等组成,且该套模型已在鞍钢厚板厂投入使用.

Abstract: 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.
