An apparatus for removing slag attached in a working hole of an electric furnace is provided to recover the removed slag into the furnace by constructing the apparatus in a simple structure, thereby efficiently removing slag attached in the working hole of the electric furnace when a tapping operation is carried out. In an apparatus for removing slag attached in a working hole(20) formed in one side of an electric furnace(10) to perform an oxygen blowing operation, the apparatus for removing slag attached in the working hole of the electric furnace comprises: crushing cleaners(50) which are formed from a heat resistant material and disposed at both sides of an inner part of the working hole, and which have nozzles for ejecting sealing gas; a cylinder(40) mounted on a metal case(12) of a furnace body of the electric furnace to move the crushing cleaners in directions in which the crushing cleaners draw close to each other or withdraw from each other; and a sealing gas feeding line connected to the nozzles of the crushing cleaners to feed sealing gas to the nozzles.
