The invention relates to a press-in treatment process method for the iron notch
sputtering of a
blast furnace, which is characterized in that a special
refractory material for an iron notch is pressed into the cold surface and the heat surface of a cooling wall, iron notch combined bricks, and the cracks and the defects of iron notch channel
brick ladles via a press-in equipment unit and by adopting the process steps of iron notch cleaning, iron notch sealing plate
welding, furnace shell pore opening, and pressure and feed quantity control. The highest pressure of construction equipment is controlled to be not greater than 30 MPa, the pressure of furnace shell press-in holes is controlled to be 1-5 MPa, the press-in quantity of the
refractory material is adjusted and controlled via a press-in equipment
control system, the press-in speed is controlled to be in a range from 10 to 75 kg per minute, and is steplessly adjusted. The invention discloses a press-in treatment process method which is low in cost and short in furnace blowout time, for the iron notch
sputtering of a
blast furnace, wherein via the press-in treatment process method,
coal gas blowby channels are blocked and sealed, so as to achieve prevention for
coal gas blowby in an iron notch area, eliminate the phenomenon of iron notch
sputtering, ensure the smooth iron tapping of the iron notch, and improve the
operating environment and the
smelting safety performance of the
blast furnace.
