摘　　要：针对热连轧机组板形遗传规律问题,建立了演变模型进行数据对比分析,在分析热连轧机组板形演变特点的基础上引入相关影响系数对遗传规律进行求解。首先建立了七机架热连轧机组板形模型,并结合热连轧工艺与设备特点对七机架热连轧机组板形数据进行了汇总,利用编制的热连轧机组板形预报软件对板形进行了模拟,在相应板形模拟数值的基础上进行了典型机架上下游间板形遗传规律纵向对比以及典型机架来料板形与出口板形差值遗传规律横向对比。根据双向对比分析结果建立了影响系数方程,利用系数方程展示了热连轧机组机架间板形演变规律和出口板形的调节因素。In view of the genetic law problem of shape of hot continuous rolling mill,the evolution model was established for data comparison and analysis.Based on the analysis of the shape evolution characteristics of hot continuous rolling mill,the relevant influence coefficient was introduced to solve the genetic law.First,the shape model of the hot continuous rolling mill with seven stands was established,and the shape data of the hot continuous rolling mill with seven stands were summarized combining with the characteristics of the hot continuous rolling process and equipment.The shape was simulated by the compiled shape prediction software of hot continuous rolling mill.On the basis of the corresponding shape simulation values,the longitudinal comparison of the shape genetic laws between the upstream and downstream of typical stand and the horizontal comparison of the genetic laws of the difference between the incoming material shape and the outlet shape of typical stand were conducted.The influence coefficient equation was established according to the two-way comparative analysis results,and the coefficient equation was used to show the evolution law of shape between hot continuous rolling mill stands and the adjustment factors of export shape.
