Apparatus for continuous slab casting

An apparatus for continuous slab casting including a slide valve mechanism, a submerged nozzle to guide molten metal from a tundish to a mold through the slide valve mechanism, a nozzle exchanging-holding mechanism to move the submerged nozzle through a moving-connecting space D provided to a base under the slide valve mechanism at the exchange of the submerged nozzle and to keep the connection between the submerged nozzle and the slide valve mechanism by pressing the submerged nozzle upward during the operation, and a rotation mechanism to rotate the base of the nozzle exchanging-holding mechanism, the apparatus comprising:

• a fixing mechanism to fix the submerged nozzle in the nozzle exchanging-holding mechanism by pressing the submerged nozzle to an inside of the moving-connecting space D of the base and to a direction perpendicular to the moving direction of the submerged nozzle at the exchange of the submerged nozzle,
• wherein the fixing mechanism comprises elastic materials or actuators provided to one of two pieces forming the moving-connecting space D, and fixes the submerged nozzle by biasing one side surface of a flange of the submerged nozzle in the moving-connecting space D and pressing an other side surface of the flange against the inside of an other piece by means of the elastic materials or actuators.
