Definitions
- the known system not only requires a complex construction, but is also complicated in terms of control technology and requires a large number of control technology for operation Facilities. Accordingly, it requires a considerable investment. Furthermore it brings with it a large degree of production uncertainty, because of the large number of continuously engaging drive units in the event of failure of part of it The entire process is stopped and the casting process has to be stopped.
- the known system there is no flexibility with regard to product quality and quality of the given manufacturing products.
- the first deformation step always be carried out, otherwise a thinness of the Product and therefore production cannot be guaranteed. So that is the known System cannot be used for certain steel qualities.
- the quality targeted and flexible temperature control of the finished product is hardly possible, especially in the case of transient conditions. If the winding unit fails, there is also the entire process immediately comes to a standstill; this also includes the standstill of the casting process a.
- a system for producing a tape in a thickness of 2 to 25 mm is from the EP-B 0 286 862 known.
- a steel strand is cast by casting Melt formed in a funnel-shaped continuous mold and as it passed through the same already deformed.
- the strand which still has a liquid core, becomes after Exit from the continuous mold so compressed that there is a weld the inner walls of the strand shells that have already solidified. This will create a Thickness reduction to a thickness of less than 25 mm achieved.
- This known system can be However, only use it for very specific steel qualities, namely those that do Allow deformation just below the continuous mold.
- the funnel-shaped continuous mold does not allow an even flow distribution, i.e. it can by the pouring jet emerging from the dip tube already strong stressed strand shell at the critical deformation points by melting weakened, which manifests itself in increased risk of breakthrough.
- Another disadvantage lies in the very low flexibility in terms of production capacity and in terms of the utilization of the full casting speed range.
- EP-B-0 327 854 describes a plant for rolling on a continuous strip casting plant cast pre-strips known, the cast pre-strip in a continuous Work step brought to the rolling temperature and rolled out into the finishing mill is introduced.
- the invention aims to avoid the disadvantages and described above Difficulties and the task is to create a system that is at high Product quality enables the production of tapes as thin as possible, with a very high Operational flexibility is given.
- continuous casting should start in the event of a malfunction a deformation stage downstream of the continuous mold can be continued.
- plate molds with plane-parallel walls can be used Find use. In connection with an immersion tube, this has the consequence that a forms even strand shell. This is neither deformed in the continuous mold still squeezed because it has a constant cross-section.
- the one out the strand emerging from the continuous mold is due to the inside of the continuous mold stable operating conditions (homogeneous conditions such as uniform lubrication and uniform cooling) on a strand shell of the highest quality, so that the Breakthrough risk is minimized and deformation of the still liquid core having strand is possible without the risk of breakthrough.
- the high flexibility of the system according to the invention enables that preferably through first two process stages, applied individually or together, a reduction in Thickness of the strand down to a thickness of 30 mm or an overlying thickness is carried out.
- the separated strand piece thus has a thickness of at least 30 mm before it is fed to further rolling. This thickness can in the case of Switching off the first two deformation stages up to the casting thickness, i.e. until preferably a maximum of 150 mm, in particular 100 mm.
- the first deformation stage preferably has hydraulically adjustable against each other Rolls causing deformation of the strand.
- A is advantageous between the separating device and the third deformation stage Device for temperature homogenization of the separated strand pieces, such as a Temperature compensation furnace provided, the device for temperature homogenization expediently with a storage device for receiving several separated Strand pieces is provided.
- the invention is based on an exemplary embodiment Schematic sketch explained in more detail.
- the one continuous has a constant cross section and is preferably designed as a plate mold.
- cast strands with a thickness 2 between 60 and 150 mm, preferably in a thickness between 60 and 100 mm (so-called thin slabs) will.
- thin slabs For continuous molds of this thickness, the use of a conventional one Dip tube 3 possible, resulting in stable operating conditions, which cooling and Melt distribution concerns, so that the leaving the continuous mold 1 Strand 4 is a uniform and stable strand shell having.
- the continuous mold 1 which is preferably straight Mold is designed to form a first Deformation stage arranged a vertical support structure 5, the hydraulic (- as indicated by pressure cylinder 6 -) the strand shell has adjustable support rollers 7.
- This Vertical support frame is divided into two sub-segments 5 ', 5' ', so that with each rope segment different forces on the Strand 4 can be applied.
- this Vertical support frame 5 becomes a so-called “soft reduction” of the solidifying strand 4 with the liquid core as the first Deformation stage performed, the load on the Strand shell in the two-phase boundary layer under one Ultimate elongation influencing end product quality remains.
- this so-called "soft reduction” one can Reduction of the strand thickness by up to 30 mm without Achieve quality losses.
- further arc segments 8, 9 are provided, which optionally also hydraulically adjustable support rollers 7 exhibit.
- a simple (possibly multi-stage) Deformation scaffold 10 passed which is used to deform the now already solidified strand 4 as the second Deformation stage (second deformation step) can be activated can.
- the strand 4 descaling in a descaling device 11 subjected to soft descaling by means of rotating Descaling nozzles and with special water wipers for the descaling water enables.
- the thickness pre-reduction allows one before the temperature compensation Influencing the end product quality especially for microalloyed steels, which are usually replaced by appropriate Stitch decreases above the recrystallization stop temperature Precipitation and recrystallization processes are influenced.
- the strand 4 preferably has the format a roughing strip, i.e. a (non-wrapable) raw material for tape production.
- the thickness 12 is preferably 30 mm and more.
- a separating device is arranged downstream of the deformation framework 7 13 for the transverse division of the cast strand 4, which depends on Requirements for the end product in the continuous caster deformed strand 4 using hydraulic scissors in the Coil weights corresponding lengths are separated.
- the resulting strand pieces 14 with a thickness of 30 to 150 mm then run into a transport and homogenization facility, e.g. a roller hearth furnace 15, depending on the slab temperature is also able to heat a thin slab.
- a transport and homogenization facility e.g. a roller hearth furnace 15, depending on the slab temperature is also able to heat a thin slab.
- this Roller hearth furnace 15 is the entire cross section of the strand piece 14, in particular their edges, to a uniform temperature brought.
- the strand pieces can are buffered (stored, e.g. by stacking), i.e. in the In the event of brief malfunctions in a part of the facility Thin slabs or strand pieces 14 added until it Resumption of the manufacturing process is coming.
- roller hearth furnace 15 Following the roller hearth furnace 15 is another Separating device, which is designed as hydraulic scissors 16 is provided, in the event of a malfunction in the following Rolling mill stage 17 functioning as the third deformation stage is activated.
- a descaling device 18 Before entering rolling mill stage 17 descaling in a descaling device 18, the preferably a rotor descaling with low water consumption and the resulting low temperature drop excellent descaling effect.
- the strand pieces are rolled in the Rolling mill stage 17, which consists of finishing stands 19.
