PURPOSE: An inert gas supplying connector of a ladle is provided which puts a ladle onto a ladle rack and connects the ladle to an inert gas supplying pipe at the same time so that an inert gas is promptly and simple supplied to molten steel in the ladle. CONSTITUTION: In an apparatus in which an inert gas is supplied to molten steel in a ladle through a gas connection port of the ladle that is put onto a ladle rack, the inert gas supplying connector of the ladle comprises a gas supply port which is installed at the outer side of the ladle so as to be connected to the gas connection port, and at the lower part of which a female cone is equipped, wherein a conical resting surface is formed on the female cone; a male cone(30) on the upper part of which a conical inserting surface that is inserted onto the resting surface is formed, in which a nozzle pipe(70) connected to an inert gas supply hose so that the front end of the nozzle pipe(70) is projected from the upper part of the male cone(30) in a certain length, and which is ascended or descended by a cylinder(82); a first arm(91) in the one side of which the male cone(30) is carried so that the male cone(30) is slid up and down, and to which the cylinder(82) is fixed; a second arm(92) one side of which is connected to the other side of the first arm(91) by means of a pin(94), and the other side of which is connected to the ladle rack by means of a pin(95); and a coil elastic spring which elastically supports rotation of the first and second arms(91,92) so as to restitute them to their initial set positions.
