  • 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.
