摘　　要：为满足某大型钢厂引进的RH炉的控制要求,开发了RH炉控制系统。系统包括基础自动化、供配电、监控和网络系统。其中,多功能氧枪控制是基础自动化系统的核心部分,采用变频器完成氧枪的驱动控制,PLC完成设备的逻辑控制。系统投产至今,运行稳定,控制功能良好,满足了超低碳钢钢水的各项工艺要求。本文重点介绍RH炉多功能氧枪的基本结构,控制系统构成,氧枪主要功能、控制流程等,并给出了控制指标。In order to meet requirement of control for imported RH furnace in a large-scale steel plant, a RH furnace control system was developed. The system includes basic automation, power supply system monitoring system and network system. Among them, multifunctional oxygen lance control is the core of basic automation system. Oxygen lance drive is controlled by inverter, and PLC is adopted to complete logic control of equipment. Since the system was put into operation, running was stable, control function was good, and it meets all process requirement of ultra-low carbon liquid steel. Basic structure of RH furnace multifunctional oxygen lance, composition of control system, main functions and control process of the oxygen lance are introduced,and control index is given.
