在对钢板圆头形状影响因素研究的基础上,通过大量的数据分析得到了钢板头部以及腰部形状函数。在体积不变的基础上,通过线性化的处理方法,成功开发出了2 800mm中厚板粗轧机平面形状控制系统定尺MAS与展宽MAS数学模型,在实际生产中取得了较好效果。 Based on the study of the influence factors on the round shape of the steel plate, the shape functions of the head and the waist of the steel plate are obtained through a large amount of data analysis. On the basis of the constant volume, the mathematical model of fixed-length MAS and broadened MAS of plane shape control system of 2 800mm medium plate mill has been successfully developed through the linearized processing method, which has achieved good results in actual production.
