  • Publication number: 20220288675
    Abstract: A sliding nozzle apparatus, configured to allow a drive unit to be attached to and detached from a slide metal frame, efficiently transmits a driving force of the drive unit to the slide metal frame. The sliding nozzle apparatus comprises a connection component attached to a slide metal frame and configured for connection with a drive unit. The connection component is provided with an opening with respect to which the drive unit can be attached and detached. The connection component is configured to allow the opening to be switched between a first position where the opening faces in the same direction as an opening-closing direction of the slide metal frame, and a second position where the opening faces in the same direction as an attaching-detaching direction of the drive unit.
