摘要
针对济钢 2 5t转炉原自动化控制系统存在的主体PLC与集散仪表系统之间通讯性能较差、难维护、故障多、自动化控制水平低等问题 ,对系统进行改进 ,设计采用多套PLC系统和多层网通讯 ,开发氧枪系统、散状料系统、煤气回收系统应用软件 ,实现了分系统的独立自动控制 ,提高了系统的自动化水平 。
Pointing to some problems included poor communication property between main PLC and assembling instruments, difficulty maintenance, more trouble, lower automati on control level etc, the automation control system of 25t converter was reformed in Jigang. Now, this system has achieved single automation control with different system, increased the automati on level and provided a condition for intellection steel-making and automation management by means of adopting multiunit PLC system and multi-layer network communication, developing computer software of oxygen lance system, and gas recovery system, etc.
