1 概况合钢炼铁厂1号高炉有效容积100m~3,设有6个风口,风口直径φ100mm,风口高度h_f=1.45m,有效高度Hu=14m,炉缸直径d=2.7m,高径比Hu/D=3.94,属细长型高炉。炉底、炉缸、炉腹采用光面冷却壁,炉腰采用一层带钩头镶砖冷却壁冷却。 1号高炉于1998年元月19日10时20分封炉待料,4月24日8时38分复风开炉,封炉时间长达94天22.3小时。由于从封炉、监护、开炉各方面工作做得较细致,复风
1 Overview Iron and steel company No. 1 blast furnace effective volume of 100m ~ 3, with six tuyeres, tuyere diameter φ100mm, tuyere height h_f = 1.45m, effective height Hu = 14m, hearth diameter d = 2.7m, height to diameter ratio Hu / D = 3.94, is a slender blast furnace. Furnace bottom, hearth, bosh smooth cooling wall, with a layer of waist with hook head tile cooling wall cooling. No. 1 blast furnace at January 20, 1998 at 10:20 pm closed furnace to be expected, at 8:38 on April 24, the wind opened the furnace, sealing time as long as 94 days 22.3 hours. As from the closure of the furnace, guardianship, open all aspects of the work done more detailed, complex wind
