Definitions

  • the invention relates to a continuous sheet caster with a strand bending device arranged below the mold and an adjoining, opposite support roller tracks, which extend from the vertical in one piece to the horizontal, circular arc guide, the bending device supporting two opposite, each bending and supporting rollers Has arch frame parts that are supported against each other and wherein the distance between the support roller tracks of the circular arc guide can be changed according to a strand cross-section to be set by parallel displacement of at least one of the support roller tracks.
  • a continuous caster of this type for example, in order to increase the strand thickness, the support roller tracks of the bending zone and the circular arc guide lying on the inside of the arc and adjoining one another are turned inwards, i.e. shifted towards the center of curvature.
  • the rollers arranged at the ends of these support roller tracks directed towards each other approach.
  • the invention aims to avoid these disadvantages and difficulties and has as its object to provide a continuous sheet caster of the type described above, in which an adjustment of the distance between the opposing roller tracks is possible in a simple manner such that the distance between the end rollers of adjacent roller tracks of the bending device and the circular arc guidance remains approximately the same.
  • one of the arch frame parts of the bending device has interchangeably fastened, interchangeable roller carriers adapted to different strand cross-sectional formats with their length.
  • An expedient embodiment is characterized in that the roller carriers are fastened to an inner part of the arch structure of the bending device.
  • the distance between the opposing bending or supporting rollers of the bending device can advantageously be changed by exchanging the roller carriers adapted to their thickness with different strand cross-sectional formats.
  • a casting thickness adjustment is particularly easy to carry out, since no adjustment manipulations have to be carried out on the bending device.
  • the roller spacing is set solely by exchanging the roller carriers. It is only necessary to loosen or attach the roller supports to the bending device. This also saves measurement work on the roller conveyor of the bending device.
  • the inner part of the arch structure is fastened to the outer part of the arch structure by means of bolts, along which one of the parts of the arch structure is slidably guided and on which this part is supported by washers against the second part of the arch structure.
  • the roller carriers are formed in one piece over the length of the bending device, as a result of which the roller carriers can be installed and removed particularly quickly.
  • roller carriers are expediently supported against the arch frame parts by means of interchangeable inserts.
  • roller carriers For easy handling of the roller carriers, they are connected to one another in a system with two or more supported bending or support rollers - with a longitudinal support member being provided at each support point - to form a unit which can be jointly installed and removed.
  • FIG. 1 is a view of a bending device from above in the direction of the longitudinal axis
  • FIG. 2 is a section along the line 11-11 of FIG. 1
  • FIG. 3 is a section along the line III-III, also of Fig. 1, represent.
  • FIG. 4 shows, in a representation analogous to FIG. 3, a system set to the largest possible casting thickness.
  • FIG. 5 illustrates a further embodiment of the system according to the invention in a representation analogous to FIG. 3.
  • a short, vertically directed guide section 1 for the strand is arranged, to which the Bending device 2 connects.
  • a circular arc guide 3 is provided below the bending device, in which the strand is guided from an almost vertical direction to an almost horizontal direction.
  • the bending device 2 which is suspended from a stationary support frame 4 by means of a nose-shaped hook 5 provided at the upper end of the bending device and which is supported at its lower end against this support frame 4 by means of a support 6, is composed of two box-shaped frame parts located opposite one another 7, 8 built.
  • guide bolts 14 are arranged on each side of the ends of the rollers 10, on which the inside of the arch frame part 8, which carries the bending or support rollers 10 forming the inside of the roller track 15, is slidably guided.
  • pull bolts 16 are provided on the side of the ends of the rollers 10, which are fastened with their heads 17 to the inner part 8 of the arch frame and which are supported with their other end 18 with interposed washers 19 on the outer part 7 of the arch frame and each with a cap nut 20 are secured.
  • the distance between the inner part of the bow frame 8 and the outer part 7 of the bow frame and thus the distance between the roller track 15 on the inside of the bow and the roller track 9 on the outside of the bow of the bending device 2 can be changed by rearranging the washers 19.
  • the bending or support rollers 10 of the roller conveyor 15 on the inside of the arch are not attached directly to the framework part as in the case of the arch frame outer part 7, but rather to roller supports 21, 22 extending in one piece over the length of the bending device 2, one crosshead 12 each with a lag screw 13 two bearing blocks 11 adjacent rollers 10 against the roller carrier 21, 22 spans.
  • the rollers 10 are formed in three parts, the rollers of the roller conveyor 15 being supported at each division point and at their ends on a roller carrier 21, 22.
  • the roller carriers 21 and 22 are fastened to the inner part of the arch frame by means of bolts 23 and nuts 24. All roller carriers 21, 22 are combined into a structural unit by means of bolts 25, on which spacer sleeves 26 are pushed.
  • the roller supports furthermore have approximately vertically directed support surfaces 27 and in each case a horizontal support surface 28, with which they are supported against transverse supports 29 arranged on the inner part of the arch structure 8 with the interposition of inserts 30 which are fastened to the roller supports 21, 22.
  • the circular arc guide 3 adjoining the bending device 2 has, in order to support the roller track 32 formed from support rollers 31 on the outside, longitudinal members 33 which are connected to longitudinal members 34 arranged on the inside of the arc, which support the support rollers 31 of the roller track 35 on the inside, by means of tie rods (not shown).
  • the direction of displacement 41 of the inner part of the arch structure relative to the outer part of the arch structure is also inclined at a certain angle 42 to the horizontal.
  • the roller carriers 21, 22, which have a length 44 at the narrowest set distance 36 are exchanged for roller carriers 21 ', 22' with a shortened length 45. This is done by loosening the nuts 24 of the bolts 23, lifting out the roller carriers 21, 22 and inserting the new roller carriers 21 ', 22' and then tightening the nuts 24 (cf. FIG. 4).
  • the area between the smallest 36 and the largest 37 distance of the roller tracks is expediently divided into several partial areas, with separate roller carriers 21, 22; 21 ', 22' etc. are provided.
  • the roller supports provided for this sub-area can be used for any other spacing of the roller tracks 9, 15, since an approximation or removal of the end rollers 38, 43 of the inner part of the arch frame 8 and the circular arch guide 3 is permissible to a certain extent.
  • the distance between the inner part of the arch frame 8 and the outer part 7 of the arch frame is adjusted by rearranging the washers 19.
  • the inner part of the arch framework is at the arch framework senteil fixed by means of two connecting bolts 46.
  • the roller carriers 21, 22 are also exchanged, although these not only have a different length 44 or 45, but also a different thickness 47, which determines the roller spacing, ie it differs also the distance of the approximately vertically directed support surfaces 27 of the roller carriers 21, 22 to the bearing surfaces 48 of the bearing blocks 11.
  • the conversion of the system from one strand thickness to another is particularly simple, since the inner part of the arch frame 8 is not compared to the outer part 7 of the arch frame needs to be moved. The number of manipulations to be carried out on the bending device 2 is thereby reduced.
  • the area between the smallest 36 and the largest 37 distance of the roller tracks 9 and 15 is also divided into partial areas, with roller carriers having a certain length and thickness being provided for each partial area.
  • the roller conveyor distance can be varied within each partial area by exchanging the inserts 30 provided between the approximately vertical support surfaces 27 and the cross members 29.
  • roller tracks 9, 32 on the outside of the arc are arranged rigidly, i.e. they are not adjusted when a roll gap corresponding to the strand thickness is set.
  • the roller tracks 15, 35 on the inside of the arc could also be immovable and the roller tracks on the outside of the arc could be set to a desired strand thickness.
