本文介绍了威远钢铁厂185m~3高炉球式热风炉的设计和运行状况。同考贝式热风炉比较,它不仅投资少,施工方便,建设周期短,而且热效率可高达76％以上;在相同拱顶温度条件下,最高送风温度可比考贝式高140℃,烟道废气温度低195℃。185m~3高炉的球式热风炉的正常运行,说明了球式热风炉在300m~3级高炉上推广应用是可行的。
This paper introduces the design and operation status of 185m ~ 3 blast furnace ball oven in Weiyuan Steel Plant. Compared with the test-bed hot stove, it not only has less investment, but also has the advantages of convenient construction, short construction period, and thermal efficiency up to 76%. Under the same vault temperature, the maximum supply air temperature can be 140 ℃ higher than that of the test- Low exhaust temperature of 195 ℃. The normal operation of ball type hot air stove of 185m ~ 3 blast furnace shows that it is feasible to promote the application of ball type hot blast stove on 300m ~ 3 blast furnace.
