一贯过程控制系统的应用与实践

Application and Practice of Integrated Process Control System

介绍了某机组一贯过程控制系统的构架、功能及模式。该系统提供了符合性图、趋势图、统计过程控制图、正态分布图以及过程统计、分析、诊断功能,对稳定生产过程、改善产品质量起到了有益的作用。另外还介绍了如何运用一贯过程控制系统解决生产中的实际问题及如何实现过程稳定控制、减少变差、持续改进产品质量。一贯过程控制系统的运用,给钢铁行业过程控制系统的实施提供了很好的平台。

The framework, functions and mode for an integrated process control system for a unit are introduced. The system can provide various diagrams, such as coincidence diagram, trend diagram, normal distribution chart, SPC chart, and process statistical, analytical and diagnosis functions, which plays a useful role in stabilizing production and improving product quality. Besides, there is an introduction how to use this system to solve real production problems, to stabilize the process control, to decrease disqualified products and to improve product quality continuously. The use of the system has provided a good platform for the iron ＆ steel industry to carry out its process control system.
