铝带热连轧的工艺过程自动控制

Automatic Processing Control System in Aluminium Hot Rolling Tandem Mill

热轧的自动化控制系统对轧制过程的稳定和带坯的精度起着十分重要的作用。目前国外在热连轧机上,已普遍采用以数学模型为基础的工艺过程控制系统(LEVEL2级)进行自动轧程表计算和轧机的设定值计算。论述了热连轧机自动化控制系统的组成,重点分析了LEVEL2级的功能及轧制策略和自动轧程表在带坯控制凸度和板形中的具体作用。

Automatic control system has a very important place to keep the hot rolling smoothly and guarantee the products accuracy.Now hot rolling tandem mill in the world mainly use automatic processing control system(level2)base on mathematical model to calculate rolling schedule and mill set-up value.The article introduces the component of the automatic processing control system,analyses the function of level2system and application of rolling strategy and automatic rolling schedule in the hot mill rolling crown and flatness control
