氧化铝厂原料磨控制系统升级改造的研究与应用

The Research of Raw Mill Controlling System Upgrade in Alumina Plant

氧化铝厂原有的原料磨控制系统功能自动化程度较低,其控制功能已不能满足自动化生产的要求,改造势在必行。改造后的控制系统结合生产工艺的实际情况,优化控制策略,建立最佳方案,充分发挥AB-PLC的技术优势,高效率地使用PLC所有设备,包括系统硬件和系统软件,显著提高原料磨控制系统的自动化程度。

As the low degree of original raw mill controlling system automation in alumina plant,the controlling function cannot meet the requirements of automation production,so it must being upgrade. After transformation,the control system combined with the actual situation of the production process,the optimal control strategy,the establishment of best practices,give full play to AB-PLC technology,efficient use of all the PLC equipment,including system hardware and software,it can significantly improving the degree of raw mill control automation systems.
