摘要： PURPOSE: An apparatus for penetrating a pressure hole of a blast furnace is provided to perform penetration work of the pressure hole without spoiling a surrounding establishment when the pressure hole which is installed along each columnar direction of the blast furnace is blocked in the process of melting a mineral and a coke which are charged from an upper part of the blast furnace. CONSTITUTION: An apparatus for penetrating a pressure hole of a blast furnace comprises a hammer drill(100), a drill bit(200), and a variable drill rod(300). The hammer drill has a connection unit(140) in a leading end and generates a rotatory power and a hammering force by a power supply. The drill bit punches a blocked part of the pressure hole of the blast furnace by a driving force of the hammer drill. The variable drill rod is interposed between the hammer drill and the drill bit and delivers the driving force generated from the hammer drill in the drill bit.
