The present invention relates to a grinding device for a tap hole for a blast furnace, which can provide convenience in closing work for a tap hole through mud injection by being installed in a mud gun in order to grind the surface of the tap hole, and can safely and rapidly perform grinding work for the surface of the tap hole. The grinding device for a tap hole for a blast furnace comprises: a main housing which can be accommodated in the inside of a nozzle tip installed at the nozzle fore-end of a mud gun; a fastening arm which is radially fixated in order to be adjacent to the external surface of the nozzle tip at the outside of the side of the main housing; a clamp which is included at the tip of the fastening arm, is combined with the inner end unit of the nozzle tip in order to prevent the turning or detachment of the main housing; a motor housing which is mounted inside the main housing by including a hydraulic motor; a motor flange which finishes the motor housing; a grinding disc which is mounted in an operating shaft of the hydraulic motor protruding to the outside of the motor flange; and a grinding tip which is fixated to the fore-end of the grinding disc in order to grind the surface of the tap hole. |
