Abstract: A coupling position switching mechanism capable of improving efficiency of a coupling position switching operation, while realizing structural simplification, and reductions in size and cost. A first coupling portion consisting of one of a slide metal frame-side coupling portion and a drive unit-side coupling portion is formed with a groove-shaped recess and a through-hole in this order from the side of a distal end of the first coupling portion, and a second coupling portion consisting of the remaining one of the slide metal frame-side coupling portion and the drive unit-side coupling portion is formed with the through-hole. The first and second coupling portions are configured such that, during a casting operation, they are coupled together by a coupling pin inserted into the through-hole of the first coupling portion and the through-hole of the second coupling portion, and during surface pressure-applying/releasing operation, they are coupled together by a second coupling pin inserted into the groove-shaped recess of the first coupling portion and the through-hole of the second coupling portion.

Abstract: Provided are a plate holding device, a plate detaching apparatus, a plate attaching apparatus and a plate attaching-detaching apparatus which are capable of reliably attaching and/or detaching a plate with respect to a plate-receiving metal frame. The plate holding device comprises: a plurality of holding members for holding a plate for a sliding nozzle device; widening and narrowing mechanisms to selectively widen and narrow a distance between the holding members; a pressing unit for pressing a central region of the plate when the plate is held by the holding members; and a force sensor for detecting a force received by the holding members and/or the pressing unit from the held plate. The plate holding device is configured to be mounted to a distal end of a robot arm.

Abstract: A plate, a plate-holding apparatus, and a holding method for the plate for facilitating work to attach the plate to a plate-receiving metal frame of a sliding nozzle device. A gap is ensured between a to-be-held portion of the plate and an inner wall surface of an engagement groove such that, when the plate is held by engaging the to-be-held portion of the plate with the engagement groove of a holding portion of the plate-holding apparatus, the plate is movable in the longitudinal direction, the width direction, and the thickness direction of the plate.

Abstract: A sliding nozzle device that can reduce any damage such as surface roughness and chipping in a nozzle hole surroundings of a used plate. The sliding nozzle device includes a fixed metal frame, a sliding metal frame, and an opening and closing metal frame that holds the sliding metal frame in a slidable manner, and in the sliding nozzle device in which sliding contact surfaces of the sliding members provided on the sliding metal frame and the opening and closing metal frame come in slidable contact with each other, the sliding contact surfaces of the sliding member of the sliding metal frame are provided away from each other by a predetermined length front and rear in the sliding direction and a part between the front and rear sliding contact surfaces serves as a depressed part, and the sliding contact surfaces of the sliding member of the opening and closing metal frame are provided away from each other by a predetermined length front and rear in the sliding direction and a part between the front and rear sliding contact surfaces serves as a depressed part.

Abstract: An opening-closing apparatus capable of, when using a robot arm to selectively open and close a component of a sliding nozzle device, reliably opening and closing the component to respective given positions. The apparatus comprises: a hand-like distal module engageable with an openable-closable component of a sliding nozzle device; a force sensor to detect a force received by the module; and a robot arm to which the module and the sensor are mounted. The robot arm is controllably operated to: move the module toward the component of the sliding nozzle device and engage the module with the component of the sliding nozzle device; then move the module to move the component, if the absolute value of the force detected by the sensor is equal to or less than a given threshold; and stop the movement of the module, when the absolute value of the force detected by the sensor reaches the threshold.

Abstract: A simplified and downsized coupling position switching mechanism capable of transmitting reliably and smoothly the driving force of the drive unit to the slide metal frame to switchably change a coupling position between the slide metal frame and the drive unit in the sliding nozzle apparatus. A coupling portion in the slide metal frame protrudes on the side of the drive unit and allows a rod head of the drive unit to be coupled thereto, and the coupling portion has a coupling space allows the rod head to be disposed movably in a sliding direction of the slide metal frame. A separator is inserted into the coupling space to divide the coupling space into first and second coupling chambers in the sliding direction of the slide metal frame. The coupling portion has a fitting section for allowing the separator to be fitted thereinto when it is inserted into the coupling space.
