摘要
对首钢京唐钢铁厂5500m^3高炉热风炉系统长寿型两级双预热系统进行了阐述，该系统的设计和实施满足了热风炉系统在采用单一高炉煤气的情况下，能够实现1300℃风温。整个系统既能高效使用高炉煤气，又能够长期可靠运行，为高炉可靠、经济、环保地运行打下了坚实的基础。
The long life, two - stage preheating system for Shougang Jingtang 5 500 m^3 blast furnace hot stove system is described in this article. With this system the 1 300℃ blast temperature can be achieved using only blast furnace gas without any enrichment gas. This system can use the blast furnace gas with high heat efficiency and can run with high credibility in a very long time, and provide a solid basis for the blast furnace to run economically and environment friendly.
