【摘要】 攀钢炼钢厂转炉提钒控制系统改造项目是攀钢根据生产和安全的需要提出的。整个改造项目包括基础自动化系统和生产过程信息管理系统两大组成部分。本文主要研究基础自动化系统。 本文在介绍了攀钢转炉提钒工艺以及主要生产设备机械电气特性的基础上，详细分析了控制系统要实现的功能，对控制系统的总体方案进行了深入的研究，设计并实现了整个控制系统。本文对分布式控制系统、现场总线、工业以太网等现代控制技术进行了较详细的介绍，并采用了光纤工业以太网、PROFIBUS-DP现场总线、西门子公司的S7 PLC和通用工业PC组成了转炉提钒分布式控制系统。论文还给出了脱硫控制、转炉氧枪控制、转炉倾翻控制等系统主要控制功能的详细设计。 该项目于2000年进行调研和考察，2001年投入运行，取得满意的控制效果，达到了攀钢炼钢厂转炉提钒控制系统改造的目的。当月生产就达到了设计水平。炼钢厂转炉提钒控制系统的改造成功，取得了很好的经济和社会效益，也为企业在旧设备自动化系统改造时的决策和实施提供了一套较为有效的方法和模式。更多还原

【Abstract】 The reconstruction projects of the control system for converter vanadium abstraction was set by Pangang Corporation to meet the market requirements and to ensure safety.　 The project includes two main parts: the basic automation system and the process information management system. This thesis is mainly devoted to the study of the basic automation system. The process of converter vanadium abstraction and the electro-mechanic characteristics of the main production devices are described first. Then the control requirements of the process are analyzed in detail. The thesis gives deep studies on the control system design. A suitable control system structure is proposed and the whole system is designed and implemented. After introduces to modern control technologies of Distributed Control Systems, Field Buses, Industrial Ethernet, the thesis constructs a control system for converter vanadium abstraction based on Fiber Industrial Ethernet, PROFIBUS-DP, Siemens S7 PLC and General Purpose Industrial PCs. The detailed design of some main control functionalities, such as desulfurizing control, inverter oxygen lance control and inverter bending control, are also proposed.The project begins in 2000, and completed in 2001. The control system resulted in very good performances, satisfies the requirements of the process for inverter vanadium abstraction. The product outputs reached the designed outputs right in the first month.　 The success of the reconstruction project has got very good economic benefits, as well as social effectiveness. It also provides an effective mode and method for implementation of other reconstruction projects in Pangang Corporation in the future.更多还原
