摘　　要：宝钢分公司2030酸洗机组三电系统面临着设备老化、备件订购困难的问题,给日常维护、系统功能完善和新功能的开发带来了很大难度。2005年2030冷轧进行了酸洗机组、轧机机组三电控制系统改造。酸洗机组增加2台S7可编程逻辑控制机,承担新分配的自动控制功能,解决了过程控制功能重新分配的难题;将原来的10台S5可编程逻辑控制机升级为S7,加快了响应速度,提高了处理效率;L2过程控制级承担了信息流管理功能。此次改造在实际生产中取得了满意的效果。Baosteel Branch 2030mm cold pickling line （CPL） ＇ s electrical, instrument and computer （ EIC ） system is fronted with two problems： One is the equipment has been aged and the other is ordering spare parts has become difficult, which makes the daily maintenance and functional development harder. The EIC systems for the pickling line and cold rolling mill were revamped in 2005. The CPL has got another two S7 programmable logical controllers, which can perform new automatic control functions. This solved a difficult problem in reassigning functions for the process controlling. The existing ten S5 programmable logical controllers were upgraded to S7 so as to accelerate the system＇ s response, which helped improve the process efficiency. L2, a process control level, performs the function of the data flow management. All in all, this revamping project has attained good effect.
