摘要:高炉炼铁是传统的炼铁工艺，也是钢铁冶金过程中最重要的环节之一，在国民经济建设中起着举足轻重的作用。但是，高炉炼铁对每个过程的要求不能忽视：配料计算是为了满足炼铁生产工艺和炼钢对铁水质量的要求，保证炼铁产品的物理性能和化学成分的稳定性；炉身温度控制能够有效提高高炉产量，延长高炉使用寿命，确保高炉运行的安全性。
本文是对炼铁高炉中配料系统及炉温控制系统做设计，通过使用相关元件，实现配料系统的自动称重及比例配料、高炉3个部位的温度控制以及循环水池温度和液位的控制。本文采用的控制方法简单，是大多数系统通用的控制方式。
通过使用亚控公司的产品组态王上位机软件，实现高炉配料系统和高炉温控系统的计算机监控功能。

Abstract:Blast furnace is traditional ironmaking process, but also is one of the most important link in the process of iron and steel metallurgy, it plays an important role in national economic construction. However, the blast Furnace requirements of each process can not be ignored: the burden calculation is in order to meet the requirements of the iron production process and the steelmaking hot metal quality, to ensure the stability of the product's physical properties and chemical composition of iron-smelting; Furnace body temperature control can effectively improve the production of Blast Furnace, extend the blast Furnace life, and ensure the security of the Blast Furnace.
This is the simple design of batching systems and temperature control system in the blast Furnace, this paper described automatic weighing and proportioning batching system, each site of the blast Furnace temperature control, through the use of electrical components and programmable logic controllers. In this paper, the control method is simple, is the most common control method. In addition, this paper includes the blast Furnace circulating cooling water temperature, level fuzzy control design.
This paper achieved batching system and blast Furnace blast Furnace temperature control system computer monitoring product configuration through the use of the kingview computer software.

本论文设计的是组态王软件在炼铁高炉冷却及配料监控系统上的应用。通过温度传感器、压力变送器等将检测到的实际温度、压力等转化为4-20mA电信号,经过数据采集模块转换成数字量信号并送到组态王中进行PID调节,通过监测高炉本体实际温度和循环水池实际液位和温度,从而实现对温度、压力等一系列参数的整定和控制。同时按比例进行配料，用电磁阀控制给料，由料斗秤称进行称重，当实际称重等于设定比例时，打开电磁阀，由皮带输送机送至小车，再由小车送至高炉。
