摘　　要：针对1+3布置形式炉卷轧机二级模型在国内外的研究和应用较少的现状,开发出一套适用于1+3炉卷轧机的二级模型系统。在介绍1+3炉卷轧机工艺特点的基础上,阐述了适用于此类轧机的二级模型控制系统,并提出了一系列专有数学模型。为精确跟踪进入卷取炉槽口的起飞长度,对不同前滑模型做了准确性分析,以保证穿带稳定性。该二级模型系统已成功应用于云南沃莱迪炉卷轧机产线,通过统计普碳钢和不锈钢的实际生产数据,得出头部厚度偏差在±0.1 mm内的命中率分别为98.5%和95.4%。Aiming at the problem of less research and application of the L2 model of the 1+3 type Steckel mill at home and abroad,a set of L2 model system suitable for the 1+3 Steckel mill was developed.On the basis of introducing the technological characteristics of the 1+3 Steckel mill,the L2 model control system suitable for this type of Steckel mill was expounded,and a series of proprietary mathematical models were proposed.In order to accurately track the take-off length into the notch of the coiling furnace,the accuracy of different forward slip models was analyzed to ensure the stability of threading.The L2 model system has been successfully applied to the production line of Yunnan World Steckel mill.The actual production data of carbon steel and stainless steel were counted,and the hit rate of head thickness deviation within ±0.1 mm is 98.5% and 95.4% respectively.
