Claims

[Claims for Utility Model Registration] 1 (a) The upwardly tapered upper part fits into a hole of the same shape formed in the bottom plate of a molten metal container, and the lower part tapers downwardly and is located near the bottom plate of the container. (b) a first base frame provided on the bottom plate of the molten metal container so as to be non-rotatable and slidable in the axial direction, and suitable for supporting the lower part of the upper nozzle; (c) a first tightening mechanism that tightens the first annular support upward; and (d) a first tightening mechanism having an upper end surface that is in close contact with the lower end surface of the upper nozzle; (e) a rail provided parallel to the first base frame via a hanger suspended from the first base frame; (f) a lower nozzle having a downwardly tapered portion adjacent to the first base frame; (g) a second base frame for the lower nozzle mounted so as to be movable in the second base frame; (h) a second tightening mechanism for upwardly tightening the second annular support located in the holder; (i) the above-mentioned The second annular support detached from the holder and the second base frame supporting the lower nozzle supported by the second annular support are moved on the rails and evacuated out of the area immediately below the upper nozzle. A mounting structure for a vertically split nozzle for a molten metal container, comprising: a sliding means; 2. Both the first and second tightening mechanisms are
The inner periphery is provided with the same number of second cam protrusions that can be engaged with and detached from the plurality of first cam protrusions protruding from the outer periphery of the first or second annular support; a rotatable clamping ring that allows the first cam protrusion to pass vertically through the space;
2. The mounting structure for a vertically split nozzle for a molten metal container according to claim 1, wherein the first or second annular support is always pressed toward the bottom plate by a cam action between the second cam projection and the second cam projection. 3. Further comprising a lifting means consisting of a rod slidably housed in a cylinder attached to the second base frame and having a rack gear carved in the vertical direction, and a pinion meshed with the rack gear, 3. The upper and lower parts for a molten metal container according to claim 1 or 2, wherein said sliding means includes a wheel attached to the second base frame for rolling and a mechanism for regulating the rolling of said wheel. Mounting structure of split nozzle.
