北京快三下什么助手:合理的老化房配置保持高爐穩定

發布時間:2018-12-12人氣:90

北京快三走势图基本走势图牛 www.iicvb.com 根據實踐,現代大型高爐配置3~4座北京快三走势图基本走势图牛比較合理。大型高爐如果配置4座北京快三走势图基本走势图牛,可以實現交錯并聯送風,能提高風溫20℃~40℃,在爐役的中后期,還可以在1座北京快三走势图基本走势图牛檢修的情況下,采用另外3座北京快三走势图基本走势图牛工作,使高爐生產不會出現過大的波動。目前,國內外許多大型高爐都配套建設了4座北京快三走势图基本走势图牛,但采用3座老化房可以大幅度降低建設投資,減少占地面積,也同樣具有非常大的吸引力。隨著設計和安裝大直徑老化房條件的改進,老化房設計的日趨合理,老化房使用的耐火材料質量也得到提高,設備更經久耐用,控制系統也日益成熟可靠,形成了多種多樣的老化房高風溫和長壽技術,使得老化房操作可以更加平穩可靠,從而保證了高爐穩定操作。以此為基礎,現代老化房的發展方向轉變為減少老化房座數、延長老化房壽命、強化燃燒能力、縮短送風時間、減少蓄熱面積、回收廢氣熱量、提高總熱效率上。另外,盡量縮短送風時間的操作方式也得到重視,基于新設計理念和完備的技術支撐,國內鋼鐵企業將老化房數量由4座減少為3座,老化房的操作模式改為“兩燒一送”,風溫的調節控制依靠混風實現,也同樣達到了高風溫的效果。

According to practice, it is reasonable to allocate 3 to 4 aging rooms for modern large blast furnaces. If large blast furnace is equipped with four aging rooms, staggered parallel air supply can be realized, and the air temperature can be increased by 20 ~40 C. In the middle and later stages of campaign, another three aging rooms can be used to work under the condition of one aging room overhaul, so that the production of blast furnace will not fluctuate too much. At present, many large blast furnaces at home and abroad have built four aging rooms, but the use of three aging rooms can greatly reduce the construction investment, reduce the area occupied, but also has great attraction. With the improvement of design and installation conditions of large-diameter aging room, the design of aging room is becoming more reasonable, the quality of refractories used in aging room is improved, the equipment is more durable, and the control system is becoming more mature and reliable. Various high-temperature and long-life technologies of aging room have been formed, which makes the operation of aging room more stable and reliable, thus ensuring the stable operation of blast furnace. On this basis, the development direction of modern aging houses has changed to reduce the number of aging houses, prolong the life of aging houses, strengthen combustion capacity, shorten the air supply time, reduce the area of heat storage, recover the heat of waste gas, and improve the total thermal efficiency. In addition, the operation mode of shortening the air supply time as far as possible has also been taken seriously. Based on the new design concept and complete technical support, the number of aging rooms has been reduced from 4 to 3 in domestic iron and steel enterprises. The operation mode of aging rooms has been changed to "two fires and one delivery". The adjustment and control of air temperature depends on mixing air, which also achieves the effect of high air temperature.
