PURPOSE: An apparatus for shutting off outflow of non solidified molten steel in a tundish is provided to improve a reuse ratio of a stopper, simplify stopper recycle operation, and reduce production cost by inserting a molten steel outflow blocking material inside a submerged entry nozzle. CONSTITUTION: An apparatus for shutting off outflow of non solidified molten steel in a tundish is for recycling a stopper (1) in a tundish after completing the casting operation. A submerged entry nozzle cutting device comprises a carrier (20) of a sliding gate (19) mounted on lower part of a tundish through a fixed axis, a cylinder operated so that the sliding gate (19) inserted in the carrier (20) is moved back and forth, and a base plate mounted on lower part of the submerged entry nozzle (7). A molten steel outflow blocking device (10) comprises a molten steel outflow blocking material (61) mounted on end part of a horizontal support beam (47) which is inserted in the submerged entry nozzle (7) for cutting off outflow of molten steel. An operation part of the molten steel outflow blocking device (10) comprises a pair of vertical support beams (44), a rotation gear operated by a motor, a horizontal support beam (47) which is coupled to end part of the vertical support beam (44), and the molten outflow blocking device (10) is mounted on other end part of which, and a tilting cylinder (50) for ascendingly operating the horizontal support beam (47).
