    Patent number: 5467810
    Abstract: An improved continuous metal casting mold incorporating a removable cassette insert member that has a uniform thickness copper facing plate and a steel backing plate fastened together in such a way as to allow three dimensional expansion of the copper plate in relation to the steel plate to minimize the thermal stresses exerted on the copper plate and the temperature differential along the surface of the copper plate.

  • Method and apparatus for slab width control
    Patent number: 5205345
    Abstract: The width of a mold is controlled effectively to produce a slab having a desired and constant width associated therewith. More particularly, the speed of the output slab and the temperature of the molten metal contained within tundish are measured and the pressure exerted by the received molten metal within mold is determined. These measured and determined values are used to appropriately modify the width of the mold so as to produce a slab of constant width.
