PURPOSE: A mud gun capable of easily adjusting close angle of tap hole is provided in which angle of front nozzle of the mud gun is changed so that the surface of the tap hole is closed by the mud gun irrespective of facing angle of the surface of the tap hole and the front nozzle when closing the tap hole after discharging hot metal in blast furnace. CONSTITUTION: The mud gun comprises a ring(20) on both outer surfaces of which an inclination plane(21) is formed so that the mud gun is rotated up and down and side to side, and to which nozzle tip is connected; a front nozzle part(10) on an inner part of which an inclination plane(11) is formed in such a shape that one side surface of the ring is received in the inclination plane, on which connection grooves(12) are formed in four directions, and in which bolt grooves(13) are respectively formed at the center of the connection grooves so that the bolt grooves are connected to socket bolts(40); and a ring fixing member(30) on which connection members(32) are formed so that the connection members are connected to the connection grooves in four directions, in which connection grooves(33) are formed in the connection members so that the socket bolts are connected to the connection grooves respectively, which is connected to the front nozzle part after the ring is inserted into the ring fixing member, and on which an inclination plane(31) for receiving the ring is formed.
