Abstract: A sliding nozzle apparatus includes a fixed metal frame, and a sliding metal frame which is provided openable-closable and slidable with respect to the fixed metal frame. When the sliding metal frame is opened, the sliding nozzle apparatus is erected such that a sliding direction of the sliding metal frame is oriented in a vertical direction. The fixed metal frame is provided with a fall prevention member, and the sliding metal frame is provided with an engagement member. The fall prevention member has a catching surface for catching the engagement member when the sliding metal frame is opened, in the uppermost position where the sliding metal frame is moved to the uppermost side in a state in which the sliding nozzle apparatus is erected such that the sliding direction of the sliding metal frame is oriented in the vertical direction.

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.
