Definitions

  • the invention relates to the rolling contact mounting of rollers for continuous casting plants.
  • the cast strand (the slab) has to be well supported by rollers during casting in order that the slab does not sag.
  • thin rollers are used, which are spaced apart at short intervals in the direction of flow of the slab, to support the slab.
  • the rollers are additionally supported.
  • the thin rollers in the axial direction of the rollers across the slab are separated in the axial direction into two axially adjacent rollers.
  • the rollers usually are provided on both axial sides with a journal in which the rollers are mounted in a bearing block via rolling contact bearings.
  • the slab cannot be guided. This produces a problem that during the casting process, the slab may sag between two axially adjacent rollers.
  • Objects of the invention are to provide a mount for rollers of continuous casting plants which are simple to produce and in which the free space between two axially adjacent rollers is as small as possible.
  • the essential element of the invention is that the rolling contact mounting between axially adjacent rollers is displaced into the roller.
  • the outer ring then rotates with the roller and the inner ring is arranged on the axle journal.
  • the interspace between two axially adjacent rollers is therefore reduced to the width of a supporting block in which the axle journal is supported.
  • a countercurrent cooling system which comprises two separate spiral or helical cooling ducts.
  • the cooling flow takes place and the return flow takes place in the second cooling duct.
  • the two cooling ducts are connected to each other on one axial side of the roller, in order that the cooling medium can flow from the first cooling duct into the second cooling duct.
  • the rolling contact bearing within the roller can be designed with a large external diameter.
  • a further advantage of this countercurrent cooling system is that the temperature differences along and within the roller should be small.
  • FIG. 1 shows an arrangement of rollers in a continuous casting plant in the prior art.
  • FIG. 2 shows a roller mounting according to the invention with countercurrent cooling.
  • FIG. 3 shows the functioning of the countercurrent cooling.
  • FIG. 1 shows an arrangement of rollers for a continuous casting plant in the prior art. An upper row of rollers is illustrated. The cast material or the slab 14 is located under this row. The rollers 1 , 1 a in the continuous casting plants have to support the slab 14 over short intervals between rollers (in the direction of flow of the slab). For this reason, the roller diameters are kept small. Because of their small diameter, the rollers are divided along the axial direction 1 , 1 a and are mounted intermediate their length, at 15 , in order that these rollers 1 , 1 a not sag excessively in a radial direction (perpendicular to the direction of flow of the slab). In this arrangement, the two rollers have journals 2 at both ends of each roller.
  • end journals 2 are mounted in rolling contact bearings 9 , 15 .
  • the slab 14 cannot be supported and may sag.
  • Adjacent sets of rollers have the intermediate mounting 15 placed at different points along the roller axes, in order that the slab not always sag at the same axial point across the arrangement.
  • FIG. 2 illustrates the inventive roller 1 , 1 a with rolling contact mountings 9 , 11 , 12 .
  • the rolling contact bearings are arranged inside the hollow of the rollers near their axial ends at the central bearing points 11 , 12 .
  • the first and second central rolling contact mountings (self-adjusting roller bearings or cylindrical roller bearings) 11 , 12 are supported on the journal.
  • the outer ring of the rolling contact bearings 11 , 12 rotates with the respective rollers 1 , 1 a.
  • Cooling of the axially outer roller 1 is shown in the section view. From the feed 3 , cooling liquid flows into the spiral (helical or thread-like) first duct 4 in the outer region of the roller 1 and then out the second outlet duct 5 . The ducts are just below the shell of the roller. At the opposite end of the roller 1 , there is a connection 6 between the first and the second cooling ducts. After the cooling medium has flowed through the connection 6 , it flows back through the second spiral helical cooling duct 5 .
  • the arrow tips and arrow ends identify the directions of flow within the cooling ducts.
  • the cooling principle corresponds to the countercurrent cooling principle (for equalization of the temperature along the roller axis).
  • the cooling medium then flows out of the roller 1 through an annular duct 7 .
  • the ducts define a flat, spiral cooling system 4 , 5 , which enables the rolling contact mountings in the rollers to be large in their external diameters.
  • the outer bearing blocks 8 and the central supporting block 10 are cooled by respective separate cooling circuits 8 a , 10 a .
  • the inlet and outlet of the cooling medium, and also the outer rolling contact mounting of the second roller 1 a of all of these cooling circuits, are not illustrated but correspond to the principle of the first roller 1 .
  • FIG. 3 illustrates the countercurrent cooling principle showing the two cooling ducts 4 , 5 arranged spirally in countercurrent relation to each other.
  • the two spiral cooling ducts 4 , 5 are connected to each other via a connecting piece 6 .
  • the feed 3 and the outlet 7 of the cooling medium are provided (but not shown).
  • the arrows show the direction of flow of the cooling medium within the first 4 and the second 5 cooling duct.
