  • Apparatus and method for horizontal casting and cutting of metal billets
    Patent number: 7028750
    Abstract: The invention relates to an apparatus for continuous casting of metal billets comprising a horizontal casting mold having and inlet end and an outlet end. It includes a feed trough for feeding molten metal to the mold inlet end and a horizontal conveyor for receiving a cast billet from the mold outlet end. A moveable cutting saw is operable to move synchronously with the conveyor for cutting a continuous billet into lengths while supported on the conveyor. The billet is resiliently supported and the saw mechanism is isolated so as to minimize transmission of low and high frequency vibrations from the cutting and conveying operations to the mold.
