Oxygen Steelmaking France has become the world's major steel-making methods. Steelmaking in oxygen, the gas purification and recovery system to achieve green is the key link in metallurgy.
Smelting in oxygen converter period produced contains a lot of carbon monoxide and iron dust in the flue gas. How rational use of emissions and the potential to significantly and iron dust, gas recovery guarantee the quantity and quality Gas recovery and enhance the protection of the environment became increasingly committed to studying and solving major task.
Based on the inspection of a large number of domestic and foreign literature on the basis of Summary of the oxygen converter steelmaking and flue gas purification and recovery technologies and the development process of research profile OG Act of converter gas recovery processes and process equipment for the research and design Finally, the converter gas recovery and purification of the automatic control system for the design and programming.
。In this paper, China's most widely used method of OG gas recovery system on the basis of the design. Flue gas purification and recycling used two control systems, PC using SIMATIC WinCC. Process parameters for the surveillance, alarm and system parameters set, the statements filed Print; Under the plan the use of Siemens S7-400 Series PLC products, completed the acquisition process parameters, Object management and the control of the data acquisition PC to PC while receiving directions.
。In recent years China's steel industry is developing rapidly and has become the world's steel giants. But clean, energy-converter is not universal. 。Therefore, this method OG Gas Recovery System Research and Extension in China is of great significance.
