Definitions

  • the invention relates to a starting strand for continuous casting plants with an arcuate strand guide downstream of a mold, in particular for the production of steel strands in slab format.
  • the invention is therefore based on the object of providing a structurally simple starting line which no longer has the disadvantages described.
  • the starting strand according to the invention is to be explained in more detail using an exemplary embodiment.
  • the starting strand according to the invention consists of a flexible, metallic band 1 which defines the width of the starting strand Tape are inserted and protrude from the surface of the tape 1 on one side.
  • These elements 3 can of course also be attached to a surface of the band, for example by welding.
  • the elements 3 have threaded bores for fastening strip-shaped spacers 2 extending transversely to the longitudinal direction of the strip by means of screws 9.
  • the spacers 2 which extend across the band 1 lie flat against one another in the area of the connecting elements 3. Between the elements 3, the spacers 2 are designed such that one side of a spacer 2 is provided with a projection 7 which engages in a corresponding recess 8 of the adjacent spacer 2. In this central area, the spacers 2 can be spaced apart.
  • the surface of the spacers 2 is covered with rubber-like plates 5, which are congruent to the surface of the spacers.
  • the free side of the flexible band 1, however, is connected to a continuous rubber-like covering 4.
  • the connection of the starting line and the covering is preferably made by gluing.
  • rubber or rubber-like is understood to mean any type of highly elastic, possibly fiber-reinforced material, which has a higher coefficient of friction than steel.
  • the position of the start-up strand during passage through the arched guide frame is such that the band 1 with the rubber covering 4 points to the center of the curve, while the spacers with the rubber plates 5 represent the outside of the curve.
  • the nature of the arrangement and design of the spacers ensures that the starting strand is rigid in one direction, but nevertheless adapts to the curve of the strand guide during passage through the arched guide frame.
  • the start-up line ensures that the transport rollers are always in contact with a material with high frictional resistance. This enables a reduction in the contact pressure and thus a structurally lighter construction of the strand transport device. It is also achieved that the starting strand does not damage the transport rollers, that direct contact between steel and steel is avoided, that the deflection of the rollers is reduced due to the reduced contact forces and, above all, the increased wear of the rollers in the area of the starting strand edges is reduced. This will make a higher one Service life of the rollers achieved and avoided that the ground roller profile pressed into the warm strand and thus leads to poor surfaces of the strand.
  • parabolically ground rollers can be used in the event that a strand with cambered broad side surfaces is produced without having to use a specially designed starting strand for this special case.
