PURPOSE: An apparatus for automatically connecting ladle bubbling plug is provided which improves productivity by automatically mounting an inert gas blowing coupler on the plug to carry out bubbling operation, thereby reducing working load, securing safety of working and shortening working hours. CONSTITUTION: The apparatus comprises first and second supporting plates(40,60) supported by a plurality of first, second and third supports(30a,30b,30c) erected adjacently to a setting position of ladle(20) comprising a plug that is a gas injection port for bubbling; a rotational operation cylinder(42) fixed onto an upper surface of the first supporting plate(40) and consisted of operating cylinder rod(44); a fixing member(46) vertically fixed onto one end surface of the first supporting plate; a rotation shaft supported by the fixing member, rotationally erected on the second supporting plate(60) and rotationally connected to the operating cylinder rod; a rotational supporting frame(70) integrally fixed onto the outer circumferential surface of the rotation shaft; and a gas supplying coupler fixed onto an upper surface of the rotational supporting frame and arranged in such a manner that the gas supplying coupler is locked to or unlocked from the plug by a back and forth moving means.
