PURPOSE: A device for clearing molten iron path of blast furnace skimmer part is provided to remove silicon solidified on the lower part of skimmer for removing slag in main iron trough for flowing molten iron tapped from blast furnace. CONSTITUTION: The device for clearing molten iron path of blast furnace skimmer part comprises a lance(31) which is equipped with a nozzle(30) for ejecting oxygen at a high pressure from an oxygen tank, and the outer part of which is covered with a refractory material, wherein the nozzle(30) is longitudinally bent in a certain angle; a flexible hose for connecting the lance(31) to the oxygen tank; a cylinder(40) connected to the end part of the lance(31) to move the lance(31) vertically; and a support(50) which is supported to the upper surface of a dust collecting hood(20) covering main iron trough that is a path of molten iron, and which fixes the cylinder(40), wherein the dust collecting hood(20) comprises a gate(21) through which the lance(31) passes, and a cover(22) for opening or closing the gate(21), and wherein the device further comprises a gate opening and shutting cylinder(23) in which the end part of piston is hinge connected to the gate(21), and the end part of the cylinder(23) is hinge fixed to the upper surface of the dust collecting hood(20) so that the gate(21) is opened or closed by the gate opening and shutting cylinder(23).
