Definitions

  • This invention relates to slide gate mechanisms for use in the casting of molten metal.
  • the present invention describes an article for securely, yet removably, mounting a refractory plate into such a mechanism.
  • One aspect of the alternative embodiment describes the mounting means as comprising a plurality of bolts loosely connecting the clamping ring and the supporting frame, and a plurality of springs between the frame and the clamping ring that urge the clamping ring against the refractory plate.
  • FIG. 6 is a cross-sectional view of Fig. 5 along the A-A plane showing the plate, clamping ring, bolts holding the ring in place and springs urging the chamfered edge of the clamping ring against the corresponding chamfered edge of the plate.
  • the metal sheath may be made from more than one layer of metal. It is known that the heat transfer coefficient perpendicular to a layer of metal is lower than parallel to the same layer. Layers of metal within the metal sheath parallel to the height of the refractory plate and perpendicular to the width of the lug can decrease heat transfer through the sheath. Lower heat transfer may result in lower operating temperatures for the lugs and, consequently, lower thermally induced mechanical stresses.
  • the mounting means can be any arrangement of mechanical elements that secures the clamping plate to the slide gate mechanism and urges the clamping plate against the plate.
  • Obvious variations include bolts, rivet or dowels in combination with any elastic material or spring that would push the clamping ring against the plate.
