The present invention relates to a device to form a pressure hole of a blast furnace. The device comprises: a pressure measurement pipe protruding from an outer wall, adjacent to a pressure hole of a blast furnace; a pushing unit placed inside the pressure measurement pipe to secure an inner path of the pressure hole while reciprocating in the pressure hole; and a screw unit placed inside the pressure measurement pipe to store the pushing unit in an inner space, and rotating by itself to induce high pressure gas into the pressure measurement pipe. As such, the pressure hole of the blast furnace is prevented from being blocked in real-time. |
