Abstract
It is intended to develop a technique of pressing and fixing a plate by a uniform force to suppress the occurrence of a crack around a nozzle hole of the plate during use, and provide a sliding nozzle device capable of improving durability of the plate, and a plate for use in the sliding nozzle device. The sliding nozzle device comprises a plate () and a plate-receiving metal frame () for fixedly holding the plate (). The plate-receiving metal frame () is equipped with: at least two holding members () each having two pressing surfaces () consisting of a longitudinally-pressing surface and a laterally-pressing surface which are protrudingly provided thereon in spaced-apart relation to each other and each adapted to be brought into contact with a corresponding one of a plurality of side surfaces of the plate (), wherein the holding members () are symmetrically arranged with respect to a longitudinal axis of the plate-receiving metal frame (); a movable block () rotatably supporting the holding members (); and pressing means adapted to press the movable block () toward the plate. An angle between the longitudinally-pressing surface () and the longitudinal axis of the plate-receiving metal frame () is set in the range of 60 to 90 degrees, and an angle between the laterally-pressing surface () and the longitudinal axis of the plate-receiving metal frame () is set in the range of 1 to 30 degrees.
