The present invention provided a stopper for continuous casting, which can control supply quantity of a molten steel by sealing an upper part of a nozzle effectively even when an inclusion is fused at an entrance of the nozzle comprised at a molten steel discharge hole of a tundish or the nozzle is deformed. The stopper for continuous casting according to an embodiment of the present invention controls flux of the molten steel by opening and closing the nozzle supplying the molten steel to a second container from a first container located at an upper part, and includes: a center rod which is extended up and down toward an inflow hole of the nozzle, and has an outer diameter larger than an inner diameter of the nozzle; a first cylinder lifting up or down the center rod; a hollow rod which has an inner diameter to accommodate the center rod in an inside thereof; and a second cylinder lifting up or down the hollow rod. Lower parts of the hollow rod and the center rod adhering to the nozzle are formed to have an outer diameter decreasing as going down to a lower part. |
