<p>A sliding nozzle device which automatically performs a series of operations of loading and unloading pressure between plates as well as opening and closing a slide frame; maintains the pressure without additional operations; and operates at full stroke during molten steel flow control. An auxiliary plate-exchanging means 20 including slide axes 21, 22 moving in the same direction as a hydraulic cylinder 19 operates, and an arm 24 having a proximal end 24a placed around the slide axis 21, the means 20 fixed on the upside frame 18, wherein a first engagement pin 26 mounted on the proximal end 24a of the arm 24 is inserted in a first engagement groove 25 formed in a first engagement member 23 engaging with the slide axis 21, and second engagement pins 28 mounted on bearings 29 are inserted in second engagement grooves 27 formed in the slide axes 21, 22. According to movement of the slide axes 21, 22, the engagement pins 26, 28 respectively move in the engagement grooves 25, 27, thereby rotating the slide axes 21, 22 and the arm 24.</p> |
