宽幅铝板带热轧计算机控制系统

Computer Control System of Wide Hot Rolling Aluminum Strip

在充分考虑宽幅铝板带热轧工艺、装备特点及板形、表面质量控制等难点的基础上,兼顾系统的开放性、先进性及稳定性,自主研发了宽幅铝板带热轧计算机控制系统,包括传动控制(L0)级、基础自动化(L1)级和过程控制(L2)级。多条工业生产线的应用实绩表明,该计算机控制系统可靠、稳定,产品性能好,温度、厚度、凸度、楔形等各项指标命中率高,可满足超宽幅铝板带热轧自动化生产及高精度质量控制要求。

Considering fully the process and equipment characteristics, shape and surface quality control difficulties of the wide hot rolling aluminum plate and strip, its computer control system was developed independently taking into account the system openness, progressiveness and stability, including drive control sub-system（L0）, basic automation sub-system（L1） and process control sub-system（L2）. The application results of several industrial production lines showed that the-computer control system was reliable and stable, product performance was good and uniform, the hit rate of temperature, thickness, crown and wedges of aluminum plate and strip were over 96%. Additionally it can meet the requirements of automatic production and high precision quality control of ultra-wide aluminum plate and strip hot-rolled.
