高炉上料的计量工作,是稳定高炉操作的重要环节.随着现代高炉操作技术的发展,对高炉上料称量精度的要求越来越高.七十年代以后,国外高炉已普遍应用微型电子计算机对高炉的冶炼操作,上料卷扬、送风、冷却等系统实现多功能的自动化监测和控制.近年来,我国高炉的自动化控制技术也在不断发展,我厂3号高炉于1983年1月起安装使用了多功能自动数字电子称系统,该系统对入炉焦炭计量实现了自动化,准确化,数字化,计量精度大大提高,达到了0.3%,为提高我厂高炉操作水平,稳步降低炼钢生
Blast furnace feeding measurement work, is an important part of the stability of blast furnace operation.With the development of modern blast furnace operation technology, the blast furnace feeding weighing accuracy requirements are getting higher and higher.Seventies, foreign blast furnace has been widely used microelectronics Computer blast furnace smelting operation, feeding hoisting, air supply, cooling and other systems to achieve multi-functional automatic monitoring and control.In recent years, China’s blast furnace automation control technology is also growing, I plant No. 3 blast furnace in 1983 1 Month installation and use of multi-function automatic digital electronic weighing system, the system of coke metering into the furnace to achieve automation, accuracy, digitization, measurement accuracy greatly increased, reaching 0.3%, in order to improve the operation level of our blast furnace to steadily reduce the refining Steel students
