Definitions

  • the invention relates to a caterpillar casting machine for producing a cast material from liquid metal according to the preamble of claim 1.
  • the cooling elements of the casting machine form the wall of a moving casting mold on the straight sections or strands of casting beads arranged opposite one another.
  • the casting beads each consist of a large number of endlessly interconnected cooling blocks that are transported along the orbits of the beads.
  • the cooling blocks are mounted on support elements which are placed on chains and are thus articulated like links in a chain.
  • U.S. 1,865,443 A a drive for a caterpillar casting machine is known, an electric motor being arranged outside a caterpillar.
  • the power transmission from the electric motor to the caterpillar takes place via a drive shaft and a worm wheel attached to it, which meshes with a drive pinion that is attached to a main shaft around which the caterpillar rotates.
  • the invention is based on the object of improving a caterpillar casting machine for producing a cast material from liquid metal with regard to the surface quality of the cast material produced and the smoothness of the caterpillar drives.
  • a caterpillar casting machine serves the purpose of producing a cast material from a liquid metal.
  • the caterpillar casting machine comprises a first guide rail and a second guide rail, with the guide rails forming two oppositely arranged endless horizontal circulating tracks, and a plurality of loose support elements with cooling blocks attached to them, the supporting elements being movably guided along the circulating paths in a transport direction, such that a continuous chain of support elements and thereby an upper caterpillar and a lower caterpillar are formed per orbit.
  • a moving mold for the cast material is formed between the cooling blocks, which come into opposition in straight sections of the upper and lower bead.
  • the caterpillar casting machine further comprises drive wheels with which the respective associated support elements with the cooling blocks attached to the upper caterpillar and the lower caterpillar are moved around the orbits.

  • the device also includes Means with which the cooling blocks in the straight runs of the caterpillars can be pressed against each other on the block.
  • both on the upper caterpillar and on the lower caterpillar - seen in the transport direction of the support elements - drive wheels are provided on both sides thereof, each drive wheel being assigned a separate drive motor, each drive wheel being attached to a stub shaft and in this way with the drive motor is connected, wherein the drive motors for the drive wheels are each arranged outside of the caterpillars, in such a way that the stub shafts on which the drive wheels are mounted do not extend through the caterpillars, ie along their width.
  • the means with which the cooling blocks are pressed against one another against one another can be a control device with which the drives assigned to the drive wheels can be controlled, preferably also regulated. Thus, different speeds can be set for the drives by means of this control device.

  • liquid metal is poured into a moving casting mold which is formed between cooling blocks which are attached to loose support elements moving in one transport direction along two oppositely arranged endless circulating tracks.
  • an upper caterpillar and a lower caterpillar are formed.
  • These two caterpillars are brought into circulation along their orbits by at least two separate drives, these drives being able to have different speeds, so that the cooling blocks in the straight runs of the caterpillars are pressed against each other to block.
  • the transport direction in which the support elements with the cooling blocks attached to them are moved along the respective guide rails and the thereby formed orbits is synonymous with the casting direction in which the liquid metal enters the moving mold between the cooling blocks is formed in the straight sections of the opposite horizontal orbits, is potted.
  • the invention is based on the essential knowledge that it is possible through the different speeds that are selected or set for the at least two drives that are each provided for the upper and lower caterpillars, the loose support elements with the attached To move cooling blocks around the orbits in such a way that the cooling blocks in the straight runs of the respective caterpillars are pressed against each other on the block. As a result, a closed surface is achieved between the cooling blocks. Such a closed surface is necessary adjacent to the casting mold, ie on the lower run of the upper bead and on the upper run of the lower bead, so that no molten metal can flow through between the cooling blocks.
  • the closed surface between the cooling blocks is necessary so that when water cooling is used, the cooling water does not reach the outside between the cooling blocks the environment can flow.
  • the above-mentioned closed surface which is formed between adjacent cooling blocks, is to be understood as "tight" because liquid metal or cooling water cannot pass through between the cooling blocks, which are pressed against one another on the block.

  • the drive motors are arranged outside the two caterpillars. This means that the shafts on which the drive wheels are mounted do not extend through the tracks, ie along their width. On the one hand, this leads to an improved use of space and less space required, and on the other hand to the advantage that these waves are not directly exposed to the heat of the casting process.
  • a control device is provided by means of which the individual drives or drive motors can be controlled. It is expediently also possible to drive the individual drives or drive motors in a controlled manner. Accordingly, it is possible during the casting process to increase or decrease the speed of selected drives or drive motors, e.g. to set a defined advance of the support elements with the cooling blocks attached to them for the purpose of generating a defined contact force between adjacent cooling blocks.
  • a control device is provided by means of which the drives with which the caterpillars are moved along their orbits are controlled, preferably regulated.
