Abstract
PURPOSE: To prevent the back flow of molten slag contained in a blast furnace to a hot stove because of a small blast press., by sealing air in the hot stove for a blast furnace after heat-accumulation, and by isolating the stove from outside so as to heat and pressurize the air.
CONSTITUTION: A press. detector 6 for use in heating and pressurizing is connected to a hot blast valve 5 set up between a blast furnace and a hot stove 1. A combustion-air-shutoff valve 7, a burner-shutoff valve 8, a fuel-gas-shutoff valve 9, and a flue valve 11 are opened, and a blast valve 10, the hot blast valve 5 are closed. The fuel is fed from a pipe 14 to a burner 15, where it is burned with combustion air sent by a fan 4 in order to heat bricks in the hot stove and the heat is accumulated. With the blast valve 10, a hot blast valve 5 closed, the burner-shutoff valve 8, the fuel-gas-shutoff valve 9, ant the flue valve 11 are closed, then with the air- shutoff-valve 7 opened, the fan 4 is driven in order to feed air into the hot stove, hereafter the air-shutoff valve 7 is closed. The sealed air is heated and expanded so that it is pressurized. The press. is detected by the detector 6. When a hot stove press. higher than the blast furnace press. is detected, blast to the blast furnace is started.
