To improve the production Procedure and lower the cost of iron-making is significant for the development of metallurgical industry and economical use of resources. Take on the reasons of the large size, complex production process, large amount of raw materials, high operating rate and the request of longevity，the operation of blast furnace is complicated. And the blast furnace is closed，it is necessary to use many detection instrumentations to monitor the internal situation. This article introduces the basic ideas for blast furnace process control、contents、and methods based on checking the large amount of references, In this paper, the design of the blast furnace temperature, flow, pressure detection systems and automatic control system for furnace top pressure on the blast furnace, as well as monitoring and control system design MCGS in the monitoring system. This system main function is carries on the dynamic surveillance to the scene Process data，saves the historical data and reports unusual signal，instructs the scene operation. The real- time control of the blast furnace main body can be finished in the hoist control room by the computer monitor control system. Key words: Blast Furnace; Detection; Process Control; Control system; MCGS 目 录 摘 要 I Abstract II 第一章 引言 1 1.1 炼铁的研究背景 1 1.1.1 高炉炼铁 1 1.1.2 非高炉炼铁 2 1.2 高炉自动测控系统的重要性 2 1.3 本文主要研究工作 3 第二章 高炉炼铁生产工艺 4 2.1 高炉炼铁的复杂性 4 2.2 高炉设备 4 2.2.1 高炉本体设备 4 2.2.2 高炉辅助设备 7 2.3 高炉生产工艺流程 7 第三章 高炉自动检测系统设计 9 3.1 温度检测系统 9 3.1.1 主要检测项目 9 3.1.2 温度检测系统介绍 9 3.1.3 检测仪表选型 10 3.1.4 热电偶、热电阻的安装 11 3.2 流量检测系统 13 3.2.1 主要检测的项目 13 3.2.2 流量检测系统介绍 13 3.2.3 检测仪表选型 14 3.3 压力检测系统 15 3.3.1 主要检测项目 15 3.3.2 压力检测系统介绍 15 3.3.3 检测仪表选型 16 第四章 高炉炉顶压力自动控制系统设计 17 4.1 炉顶煤气压力控制系统简介 17 4.2 控制系统方案选择 1
