Definitions

  • a suspension system for linearly reciprocating the lifting stage of a continuous casting process mold relative to a fixed structure an elongated double lever having first and second ends, a pivot for supporting the lever intermediate the first and second ends, a first plate pivotally secured to the second end of the lever and to the lifting state, a plurality of articulated plates, one end of each of which being pivotally secured to the lifting stage, the other end of each of which being pivotally secured to the fixed structure, and drive means pivotally secured to the first end of the lever whereby the lever is arranged to move angularly relative to the pivot and the suspension system is adapted to generate a lemniscate curve, the lifting stage movements being derived from the substantially straight portion of the lemniscate curve.
  • This invention relates generally to suspension structure for continuous casting, and relates more particularly to an improved suspension system for the lifting stage that houses the mold used in a continuous casting process.
  • a suspension of the lifting stage is provided in such a manner that the lifting stage is guided, through a guiding system, which generates a so-called lemniscate curve or figure-eight curve.
  • the lifting stage movements are derived from the almost straight portions of the lemniscate curve.
  • a further aspect of the present invention is the arrangement of the points of rotation or pivots in prestressed roller bearings that are used for the purpose of eliminating any form of bearing play.
  • the construction of the present invention assures that the mold moves back and forth without deviating from the required linear motion.
  • FIG. 1 is a fragmentary side elevational view, partly in section, of one embodiment of this invention
  • FIG. 2 is a plan view of the apparatus shown in FIG. 1;
  • FIG. 3 is a fragmentary side elevational view, partly in section, of a modified embodiment of this invention.
  • FIG. 4 is a plan view of the apparatus shown in FIG. 3.
  • the fishplate or plate-type construction illustrated in FIG. 1 provides for the suspension of the lifting stage 1 for the mold (not shown) on a total of eight pivots such as pins 2 four each at the upper portion and four each at the lower portion, with the pins 2 disposed opposite each other in each case, whereby the guiding linkage system is formed by the fishplates or plates 3 and 4.
  • One end portion of the fishplates or plates 4 is connected, in each case, to the fishplates or plates 3 by means of pins 5.
  • At the other end portions of fishplates 3 are mounted in a pivotable manner in bearings 7 by means of pins 6; the bearings 7 are mounted on the framework of the casting machine.
  • the action is started by means of a crank 8 via a connecting or driving rod 9 which in turn is connected to one end of a double lever 11 by means of a pin 10.
  • the double lever 11 is mounted in a pivotable manner in a bearing 12.
  • the double lever ll With its other end, the double lever ll, while encircling the lifting stage I at two opposite sides in a bifurcated manner, is connected with fishplates or plates 14 by means of pins 13; the fishplates 14 are connected with their other ends to the pins 2 in a pivotable manner.
  • FIG. 1 depicts the emerging hollow casting at 15.
  • the second possibility of a guiding device construction is shown in FlGS. 3 and 4 with the guiding device creating the same effect as the one discussed before.
  • the fishplates or plates 19, are hinged at one end to the fishplates 18 by means of pins 20 and are hinged at the other end to bearing 22 by means of pin 21, with the bearings 22 being mounted on the framework of the casting setup.
