摘要： PURPOSE:To prevent occurrence of pollutional defect such as noise, scattering of dust, discharge of harmful gas, etc. at the stage of releasing high pressure exhaust gas from the top of a blast furnace by adding a little reconstruction to an existing equalizing device at a top charging hopper of a blast furnace operating at a high pressure. CONSTITUTION:When a raw material is charged to a two-bells one-valve type high top pressure operation blast furnace 1, a primary equalizing valve 18 in a primary equalizing pipe 17 connecting to a small bell hopper 6 is opened, and the gas in said hopper 6 is stored in the primary equalizing pipe 17 up to a stop valve 29 to perform the primary release. Then the valve 18 is closed and a releasing valve 25 is opened to perform the secondary release of the hopper 6; a sealing valve 9 is opened and the raw material is fed to the small bell hopper 6 through a swing chute 2. The stored waste gas between the valves 18 and 29 is then returned back to the hopper 6 to equalize the pressure in the hopper 6 to the inside pressure of a large bell hopper 7; thus, the small bell 4 is lowered and the raw material is charged to the large bell hopper 7. The large bell hopper 7 and the top of the blast furnace 11 are connected with an equalizing pipe 10 and the pressure inside of both are equalized. The large bell 5 is thus lowered and the raw material is fed to the furnace 11.

摘要： PROBLEM TO BE SOLVED: To provide a method for operating a blast furnace, which can prevent the furnace from falling in a bad condition during a low RAR operation, particularly can prevent poor heating for a charged material in the upper part of the furnace, when operating a normal blast furnace, and can stably lower the raw material without causing the fluidization or agitation of a charged layer of the raw material due to the blowing of a gas from a shaft portion. SOLUTION: The method for operating the blast furnace includes: providing a gas-blowing portion (A) between a position p 1 and a position p 2 in the furnace height direction, when representing the radius of the furnace port of the blast furnace by R 0 , the position at which the depth from a stock line is R 0 by p 1 , and the position at which the height from the lower end of the shaft portion is 1/3 of the total height of the shaft portion by p 2 ; blowing a hot blast having an oxygen-enriched rate of 20% or less by volume into the furnace from a tuyere; and blowing a preheated gas from the preheated-gas-blowing portion (A).
