Definitions
- the invention relates to a device for continuous casting and deformation of a cast strand of metal for producing, for example, slabs, wherein in the continuous casting of the vertically emerging from a mold casting strand is guided by means of a set of Richttreiberrollencruen and support rollers strand guide in the casting direction and bent into a horizontal outlet level ,
- Continuous casting plants of the type mentioned are well known in the art, wherein depending on the diameter of the casting strand a diameter of the bending radius is usually made between seven and twelve meters and the bending process itself in a completely solidified casting strand or cast strand with still liquid core.
- the cast strand is first conveyed in the casting direction by pairs of propeller rollers and supported by support rollers, wherein the pairs of propeller rollers additionally have the task of providing good alignment and conveying.
- pairs of propeller rollers additionally have the task of providing good alignment and conveying.
- the object of the invention in this prior art is to develop a continuous casting so further that an increase in system flexibility achieved and a quick format change is possible.
- Strand guide segments essentially consist of at least two opposite roller pairs whose roller bodies are connected to one another via traverses, support elements and bearing elements to form roller conveyors.
- the upper roller conveyor is connected via guide elements such as slides or handlebar systems with the lower roller conveyor.
- the roller gap formed between the roller conveyors is variable and can be adjusted for example via hydraulic cylinders.
- the strand guide segment is designed as an exchangeable exchange unit in such a way that a rapid change with a then required second strand guide segment can be carried out when the product format to be produced changes. Also for the conversion of the strand guide of Richttreibem in a strand guide segment may be calculated with a fast change time, it is under 24 h (also applies to the deconstruction).
- the strand guide segment according to the invention may be formed as an arc segment or exercises a directional function, the directional function of the reference points of the original Richttreiberrollenzies essentially (slight or small shifts are possible) and taken by an extension or increase the reference point number a refinement of the previously existing Straightening concept for reducing the strand elongation is made possible.
- the area of the complete, double-sided supported strand guide is extended by the strand guide segment in relation to the previously limited driver area, whereby an increase in production speed is made possible not only in combination plants, but also for pure slab plants which have a driver system in the directional range, such as vertical systems, CSP plants, thick slab plants.
- a driver system in the directional range such as vertical systems, CSP plants, thick slab plants.
- the strand guide segment can advantageously be used in different strand guide concepts, for example in vertical, circular arc and vertical bending systems for the production of carbon steels, stainless steels and stainless steels with various casting formats such as thick slabs, slabs, thin slabs, blocks, pre-profiles (BBL formats ) Truncheons and combined units.
- FIG. 2 shows a strand guide with strand guide elements as a schematic diagram
- FIG. 3 shows the strand guide of FIG. 1 as a technical drawing
- FIG. 1 shows a strand guide 3 for a cast strand 1 in the block or pre-profile format according to the prior art.
- the casting strand 1 which emerges vertically from a mold (not shown) extends in the direction of casting 2 in the illustrated schematic diagram from top right to left into the horizontal outlet level 4 predetermined by the strand guide 3.
- the casting strand 1 is supported in the strand guide region shown with five support roll pairs 6, the strand guide line of the fixed side 7, the strand guide 3 following, are arranged accordingly.
- a support on the strand guide line of the lot side 9 (the fixed side 7 opposite) is not required due to the block or Vorprofilformats.
- three Richttreiberrollensectione 5 are arranged to promote it, so that there is a straightening system with three drivers here.
- FIG. 2 shows a strand guide 3 'according to the invention for a cast strand 1 in the slab format.
- the strand guide 3 1 now no longer contains three Richttreiberrollenrune 5, but only two, since a Richttreiberrollen- pair 5 by a strand guide segment 10 with directional function and a strand guide arc segment 11 has been replaced.
- the strand guide line of the loose side 9 is supported in the front region of the strand guide 3 ', as required by the slab format, while the strand guide line of the fixed side 7 remains unchanged.
- the completely supported region of the strand guide 3 ' is considerably lengthened by the strand guide segments 10, 11 compared with the prior art.
- additional Richtrati 8 given compared to the Richttreibererrollencruve 5 exchanged through the strand guide segment 10 additional Richtrati 8 given.
- FIGS. 3 and 4 the straightener configurations shown in FIGS. 1 and 2 in the form of schematic diagrams are shown in the form of technical drawings for better illustration, the same reference numerals being used.
