摘要
叙述了一种采用电子皮带称 +称量控制仪表 +PLC+变频调速器 +工控计算机及数据通信网络等组成的预配料自动控制系统。介绍了该系统的构成、过程监视、实时监控设计及其实现。改造后运行结果表明 ,单机配料精度由原来的± 3 %提高到± 1 % ,系统配料控制误差由原来的 5%减少到 2 %以内 ,为涟钢的烧结矿产量和质量提高发挥了较大作用 ,年增经济效益 1 2
The article describes an automatic control of mixture system which is made up of electronic strap balance and quantify control instrument and PLC and frequency conversion activator and industrial control computer and data communication net and soon. It introduces concretely the composition of the system, design of the procedure super vision and control inline and how to realize. After reconstruction, the running result indicates that the precision of single machine's mixture increase from ±3% to ±1% and the system error decrease from 5% to 2%. The reconstruction of this system enbances the quantity and quality of the sinter. It brings out economic benefit 1 200 000 Yuan every year.
