PURPOSE: A supporting device of a submerged nozzle is provided to effectively disperse thermal stress caused by high temperature which is transferred from a high temperature submerged nozzle to a submerged nozzle holder. CONSTITUTION: A supporting device of a submerged nozzle includes a submerged nozzle holder(110); a hanger(120) which holds the submerged nozzle holder; and a main body(130) which is fixedly connected to the hanger. The submerged nozzle holder has a hollow part which has a larger diameter of the upper part than a diameter of the lower part, and which forms an inner shape. The submerged nozzle holder comprises a pair of support bars on the position of the outer surface corresponding to the hollow part. The center axis of the support bar is positioned on the lower side of the middle point of the height of the submerged nozzle holder. The hanger, which holds the submerged nozzle holder, has a pair of mounting grooves which hold the support bars. |
