一、前言首钢一烧结环保治理大修工程自动控制部分,从82年12月到83年5月,用了半年时间就将集散型控制系统网络90(NETWORK-90简称N-90)投入运行。经过一年多的试验改进,网络90系统基本上达到了设计的主要目标,实现了烧结生产全过程的计算机控制。并且首创国内无指示仪表,无模拟盘,无键选台的控制系统。体现出了当 I. Foreword Shougang Sinosteel Environmental Control overhaul automatic control part of the project, from December 82 to May 83, took six months to put the distributed control system network 90 (NETWORK-90 referred to as N-90) put into operation. After more than a year of trial and improvement, the network 90 system basically reached the main goal of the design and realized the computer control of the whole process of sintering production. And the first domestic no instructions instrument, no simulation of the disk, keyless election control system. Reflected when
