Abstract:
A dipped nozzle changer capable of changing a dipped nozzle by supporting the lower surface of the flange part thereof by a plurality of keyboards installed on both sides of the nozzle parallel with each other and extruding a used dipped nozzle horizontally by a new dipped nozzle, comprising pressing force energizing mechanisms for varying the deflection amount of a spring body continuously according to the movement position of the dipped nozzle at the time of replacement of the dipped nozzle so as to assure a higher sealability of a connection surface between the dipped nozzle and a refractory above the dipped nozzle and formed independently of each other for each keyboard so as to vary the dipped nozzle pressing force produced in each keyboard simultaneously and a slide frame having a spring body support seat surface partly forming a tapered surface thereon, wherein the dipped nozzle comprises a recessed surface of 1.0 to 10 mm in depth for holding a seal member installed at the center of the sliding surface thereof, and the closing fire−proof plate is thicker in thickness than the flange part of the dipped nozzle, has a thickness difference of at least 12 mm, and has the upper surface both end parts at right angle to the extruding direction recessed over the area of at least 10 mm in width and 12 mm in depth.
