Control Model of Accelerated Cooling for On-Line High-Density Pipe Laminar Flow in Plate Mill
-
摘要: 根據鞍鋼厚板廠投產的國內第一套中厚板軋后高密度管層流控冷裝置的特點,結合理論分析,建立了一套適用于中厚板軋后快冷的控制用數學模型.該模型由層流冷卻預設定冷卻模式、各預設定冷卻模式下終冷返紅溫度預報模型、終冷返紅溫度修正模型、自學習模型等組成,且該套模型已在鞍鋼厚板廠投入使用.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.
