摘要： A submerged nozzle opening/closing device of a tundish is provided to open and close a submerged nozzle precisely by preventing the thermal transformation by molten steel flowing into the tundish through a heat-resistant type drive unit. A submerged nozzle opening/closing device of a tundish comprises: a body(120) arranged to be adjacent to a tundish(2); an inner strain driving unit mounted at the body in order to prevent the thermal transformation; and an opening and closing member(160) opening and closing a submerged nozzle(5) of the tundish, while being connected to the driving unit. The driving unit includes: a driving source(142) generating the driving force elevating the opening and closing member; a supporting member(144) connected to the driving source to be lifted, delivering the driving force; a heat-resisting member(146) whose one end is connected to the opening and closing member and the other end is connected to the supporting member; and an insulating member(150) inserted between the supporting member and heat-resisting members in order to prevent the heat from being delivered to the supporting member.
