  • Patent number: 6026887
    Abstract: Steering, tensioning and driving a revolving metallic casting belt in continuous casting machines wherein the belt travels along a generally straight casting plane P. Two two-axis robotic mechanisms are positioned at opposite ends of an exit-pulley drum, each including a "floating" housing carrying a bearing rotatably supporting a journal at the respective drum end. A drive shaft connected to one of the journals rotates the drum for revolving the belt. The robotic mechanisms adjustably position opposite ends of a rotating drum in X--X plane parallel with plane P for tensioning the belt and in Y--Y plane perpendicular to plane P for steering the revolving belt. These robotic mechanisms are controlled to operate in any of several modes: (1) "Walking-tilt" steering keeps the belt much closer to an exiting product than prior art, the belt being flatter and in better contact with the product for improving casting speed and quality.

  • Patent number: 4934441
    Abstract: For closing gaps between blocks of a moving edge dam prior to its travelling downstream into the entrance of a moving mold defined between upper and lower revolving casting belts moving downstream from the mold entrance to its exit, the moving edge dam is initially elevated into a crest, as shown in FIGS. 12 and 14. This crest is above a plane generally defined by the lower casting belt travelling downstream. Then, a guide roller positioned above thrusts downwardly upon the moving edge dam bending it convex downwardly as shown at "B" in FIG. 14 for causing its dam blocks to press against each other for sliding them along their high strength endless flexibile carrying member, thereby closing gaps between the blocks entering the mold entrance for sealing the entrance against outward leakage of molten metal between blocks.

  • Patent number: 4694899
    Abstract: A method and system are provided for synchronizing the travelling edge dams in the continuous casting of metal slab, strip, or bar, thereby providing a means for the continuous uniform casting of longitudinally spaced edge shapes, contours, or profiles such as integral shoulders, lugs, lobes, depressions, curves, or indentations in the opposite edges of the cast product. Shapes include the protruding lugs, cast directly opposite each other, for suspending copper anodes in electrolytic refining-also the intruding, material-saving contours in the tops of anodes. A belt-type continuous casting machine is shown wherein two moving contoured edge dam loops each comprise blocks strung upon flexible endless metal straps. The moving edge dams on each side of the mold must be synchronized, regardless of disturbing thermal variations notably.

  • Patent number: 4422645
    Abstract: A gameboard and carrying case wherein the gameboard is of pliable material, such as leather, so that it is adapted to be rolled into a roll and a carrying case for the gameboard which receives the gameboard when in a rolled condition and in which there are also received within the roll of the gameboard in the bore of that roll, the playing pieces which may be stored in a gamepack for storing play pieces. The game pack may comprise a pair of bags with a maximum opening less than the interior of the rolled gameboard and received within the rolled gameboard.
