ABSTRACT:
A surface pressure loading and releasing mechanism in a sliding nozzle device for a molten metal vessel is used to reduce the hot manual work involved in loading and releasing surface pressure on plates and to carry out loading and releasing of the surface pressure by a simple operation. In a sliding nozzle device for applying and releasing surface pressure between plate bricks by moving an opening/closing metal frame having elastic force loading and a sliding metal frame disposed between a fixed metal frame and the opening/closing metal frame, a surface pressure block is removably disposed between brackets for mounting the opening/closing metal frame on the fixed metal frame. Surface pressure loading and releasing is carried out by moving the opening/closing metal frame, by causing a projecting portion of the sliding metal frame to project into the opening/closing metal frame, and by having a molten steel passage hole in the sliding metal frame passing therethrough abut with the opening/closing metal frame.
