摘　　要：传统的加热炉手动点火,操作人员危险性高,且点火周期长。莱钢1 500 mm宽带钢加热炉自动点火系统采用德国SIEMENS公司的S7-200控制系统,控制系统应用PID自整定原理,完成自动点火煤气压力的自动调节回路控制。自动点火系统完成自动点火控制、数据采集、工艺显示、历史数据存储、故障报警及报表打印等功能。通过这些技术的应用大大提高了加热炉点火的安全性,降低了工人劳动强度,缩短了点火时间。The heating furnace is ignited manually, then the operator is dangerous and ignition cycle is long. The S7-200 control system of SIEMENS is adopted in the automatic ignition system of LAIGANG 1 500 mm strip steel. The control of automatic ignition for ignition burner and flame detection are realized. The data collection, technics show, history data storage, fault alarm and report print are achieved by applying PID theory. The security of ignition is improved, the work intension is reduced, the ignition time is shortened by using these technology.
