Patent
CA 2255123
A sliding gate nozzle device is disclosed which, even when the position of a retreat or advance limit of a sliding metal frame changes, can effect the application of a surface pressure and ensure a gap for the entry of surface pressure blocks therein and which can relieve the applied surface pressure easily. The sliding gate nozzle device comprises a fixed metal frame 1, an opening/closing metal frame 2 movable with respect to the fixed metal frame 1, a sliding metal frame 3 disposed between the fixed metal frame 1 and the opening/closing metal frame 2 and slidable up to a limit position, and a surface pressure applying mechanism which presses the opening/closing metal frame 2 against the fixed metal frame 1 when the opening/closing metal frame moved to a surface pressure applying position W. In the sliding gate nozzle device, the opening/closing metal frame 2 is co-moveded with the sliding metal frame 3 and a surface pressure applying member 12 which prevents the sliding metal frame 3 from reaching the above limit position when the opening/closing metal frame 2 has reached the surface pressure applying position W is disposed removably between the opening/closing metal frame and the sliding metal frame. The "limit position" means an advance or retreat limit in a movable stroke range of the sliding metal frame.
