热轧带钢生产线各机架轧制力、板宽、板厚控制系统 ,须根据轧制工艺计算设定参数 .但在实际运行中 ,由于各种干扰因素的影响 ,往往偏离系统设定值 ,本文根据分布式数据采集系统的基本数据库 ,通过轧制工艺参数约束方程 ,运用数据融合方法 ,对实际轧机运行状态作出综合分析 ,为进一步优化轧机运行参数提供重要参考 . Hot rolling strip production line of each rack rolling force, width, thickness control system, according to the rolling process to calculate the set parameters.But in actual operation, due to various interference factors, often deviate from the system settings Based on the basic database of distributed data acquisition system, this paper makes a comprehensive analysis of the actual rolling mill operating status by using the data fusion method through the rolling process parameter constraint equation, which provides an important reference for further optimizing the rolling mill operating parameters.
