Abstract：In Jinan Steel due to persistently high of the temperature of hearth sidewall for No.1 blast furnace with 1 750 m3 volume, the blast furnace blowing off and overhaul were carried out at the same time maintenance of the machine. Combined with the blast furnace operation and the hearth corrosion, residual iron were tapped to the ground, residual iron mouth located at No.15-16 tuyere direction, elevation of 7.4 m, up 15°, and the pool of containing iron is constructed. Owing to fully planed work, residual iron tapping process was clean and safe and smooth, which lasted nearly 10 h, discharged residual iron 576 t.
