Summary:Provided in the present invention is an apparatus to prevent a mud gun from being pushed back from a tap hole of a blast furnace. The apparatus comprises: a gear part provided to at least a part of a circumferential surface of a rotary shaft which rotates the mud gun; and a locking part which prevents rotation of the rotary shaft by locking the gear part. The locking part prevents a reverse rotation of the rotary shaft, thereby preventing the mud gun from being pushed arbitrarily. 본 발명은 고로의 출선구로부터 머드건의 임의 밀림을 방지하기 위한 장치로서, 머드건을 선회시키는 선회축의 외주면의 적어도 일부에 제공되는 기어부; 및 기어부를 로킹하여, 선회축의 회전을 방지하는 로킹부를 포함하는 것을 특징으로 하여, 로킹부가 선회축의 역회전을 방지하는바, 머드건의 임의 밀림 자체를 방지하는 효과를 제공한다.
