ABSTRACT:
A sliding nozzle unit in which a face pressure load is released by inserting a cotter into a press member provided in an open close metal frame and sliding the cotter on an inclination block provided on the side face of a sliding metal frame thereby flexing a resilient body through the press member. The inclination block is spaced apart from the nozzle hole of a sliding plate on the longitudinal side face of the sliding metal frame. Inclining face of the inclination block is formed to become lower toward the direction for fully closing the nozzle hole and a stop member is provided on the longitudinal side face of the sliding metal frame, in the vicinity of nozzle hole of the sliding plate, so that the nozzle hole is not fully opened under a state where the cotter is inserted into the press member. Alternatively, the inclination block may be disposed closely to the nozzle hole in the longitudinal side face of the sliding metal frame, the inclining face of the inclination block is formed to become lower toward the direction for fully opening the nozzle hole and a stop member may be provided to be closer to the full close side than the inclination block, and on the longitudinal side face of the sliding metal frame so that the nozzle hole is not fully opened under a state where the cotter is inserted into the press member.
