Claim:
A sliding nozzle device for casting, comprising: a plate; a plate-receiving metal frame for fixedly holding the plate, a movable block positionable within said frame; at least two holding members each having two pressing surfaces consisting of a longitudinally-pressing surface configured to press against a longitudinal surface of the plate, and a laterally-pressing surface configured to press against a lateral surface of the plate, the longitudinally-pressing surface and the laterally-pressing surface extending in spaced-apart relation to each other, wherein the holding members are arranged on opposite sides with respect to a longitudinal axis of the plate-receiving metal frame, said at least two holding members pivotably connected to said movable block about a pivot axis; and pressing means connected to the frame and adapted to press the movable block toward the plate, wherein 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.
