摘要
介绍了承钢物流管控中心综合料场采用美国GE 90-70系列PLC控制系统及光纤环网的网络结构,很好地适应了设备多、采集分站多、地域分布广、实时性要求高、系统可靠性要求高的特点;系统投运后,设备故障率降低了3%,混合料配比指标SO2、TiFe的稳定率达到95%,满足了高炉、烧结、焦化系统对原料的稳定要求。
It is introduced the network structure composed with PLC control system of American GE 90-70 series and optical fibre circle net,applied in the comprehensive material field of Cheng Steel.It meets the demand for multi-equipments,multi gathering station,wide area distribution,high real-time performance and high reliability.After it is put into use the equipment breakdown ratio reduces by 3%,steadiness ratio of mixing charge proportion index of SO2 and TiFe reaches 95%,it meets the requirements for raw material from blast furnace,sintering and coking system.
