To provide a tundish nozzle comprising a cone part, an inner pipe and an outer pipe, and a tundish nozzle removal tool for simply removing the tundish nozzle and preventing safety accident. In a tundish nozzle(10) comprising a cone part(12) inserted into tundish(116), an inner pipe(14) connected to the cone part and an outer pipe(18) connected to the outer side of the inner pipe, the tundish nozzle is characterized in that holes(18a,18a') are formed on the outer circumferential surface of the outer pipe at both sides in a diameter direction of the outer pipe. The removal tool(20) of tundish nozzle comprises two hook parts(22) respectively inserted into the holes at both sides of the outer pipe of the tundish nozzle; a rectangular link part(24) comprising four hinge shafts(34a-34d) and four links(36a-36d) such that two hooks(32,32') are hinge connected to end parts of the four hinge shafts and the four links to form a rectangular link; and a rod part(26) that is hinge connected to the rectangular link part, wherein the rod part comprises a stroke adjusting pipe(38) which is hinge connected to the rectangular link part, and on which a plurality of through holes(38a) are perpendicularly penetratingly formed along length of the stroke adjusting pipe with being spaced from one another in a fixed distance, and an inner rod(42) inserted into the stroke adjusting pipe and connected to one of the through holes by a fixing pipe. |
