Definitions
- the invention relates to a continuous casting method according to the generic term of Claim 1.
- Slabs are the starting material for the production of sheet metal and Tapes. Are slabs with a thickness of> 100 mm in Continuous casting plants produced, segregation problems occur. According to the DE-OS 24 44 443 the problem is to be solved by the fact that within the continuous caster on the strand within the solidification section, Deformed as soon as possible before the solidification point with a degree of reduction of 0.1 to 2%.
- the invention has for its object to provide a method with a product with a high proportion ( ⁇ 80 %) is made available to the roll structure with which the casting plant leaving thickness dimension is coilable.
- the invention is based on a continuous casting process for production of slabs with a reduced thickness compared to the as-cast state.
- steel is poured into a continuous mold and an in Cross-section of partially solidified strand subtracted.
- the strand will performed between pairs of rollers.
- Some pairs of roles can Segments are summarized.
- For the strand transport of the strand some of the rollers can be driven.
- the roles or the segments are hydraulically adjustable against the strand.
- the roles or some of the Rolls or roll segments, both within the solidification section and also in the area of the solidified strand have a deforming effect on the Strand one.
- the degree of deformation is either via the hydraulic pressure Adjusting device adjustable or by stops (spacers) limited to the roles.
- each adjustable, driven roller is now one Controller assigned to the speed and the contact pressure of the rollers and the current consumption of the roller drives recorded and according to predetermined Regulates setpoints; each controller also has a higher-level one Controller connected, to which the position of the sump tip (end of the Solidification distance) is known.
- This controller sets them individually adjustable roller pairs and the strand speed in such a way that the swamp tip is in or just in front of a pair of rollers that oppose Stops on its distance is adjustable and thus the gauge block and the withdrawal speed of the strand, as well as the degree of deformation in the solidified area.
- the location of the swamp tip can be changed the different speeds, the current consumption of the drives of two neighboring pairs of rollers and the reaction forces of the strand be taken as the speed of the strand between solidification distance and solidified area at one Strand deformation changes.
- the reaction force of the strand can be the differences between the deformation force - e.g. by Pressure measurement of the hydraulic medium or via pressure transducers at the Roller pin - and the deformation work performed (adjustment of roles) can be determined.
- the higher-level controller receives the Invention also from the machine data of the continuous caster Information about steel temperature, quality, Pulling speed of the strand and the position of the rolls due to the freely occurring stitch acceptance in the respective pairs of roles. This data is also stored in the Setpoints of the individual controllers incorporated.
- the advantage of control method according to the invention is in a freely adjustable Distribution of strand deformation over the area of Solidification distance and the solidified area, one quality-adjusted deformation treatment of the strand, less Load on the roles causing the deformation and the production of a product with a high degree of rolling structure. By the latter will also improve the mechanical Properties of the end product compared to conventional ones Manufacturing methods achieved.
- the speed of the rollers be checked and corrected using an average value, the is formed from the speed of a first and third roll of into groups of three, driven, immediate successive roles, the speed of the middle Role of this mean within a tolerance range corresponds to, which is not greater than the difference in speed the first and third roles.
- Liquid steel is placed in a mold 1 with a thickness of approx. 60 mm (distance of the Broad sides of the mold from each other) poured.
- the mold 1 downstream are rollers 2 to support the still thin strand shell of the partially solidified strand 3 is provided.
- Rolls 2 follow Section in which the roles are combined into a segment 4.
- Individual rollers 5 of the segment 4 are driven.
- the roles 5 are individually or as a segment by means of hydraulic cylinders 6 against each other employable. Even under the deformation of the Strands the bottom of the swamp in the area of segment 4 through Influencing the speed of the rollers kept.
- This section of the Roller guide (segment 4) is followed by a section 7 in which rollers 8 driven and against not shown attacks on a certain Measure against each other to achieve a specific decrease in thickness Strand and a certain final thickness of the strand are adjustable.
- Change due to the deformation in the solidified area of the strand the speeds of the rollers correspond to those between the individual ones Pair of rolls taken from the stitch. Because the roles only on that 20 to 15 mm, the speed must be in one wide range can be changed.
- the speeds of each Rollers are derived from the current consumption of the drives of the respective roll, the hydraulic pressure and the distance between the rollers determined and adjusted. In order to carry out this procedure, the method shown in FIG shown control loop used.
- the strand emerging from the mold 3 reaches a first pair of rollers 9, 9 '.
- the role 9 is by means of a Hydraulic cylinder 11 adjustable.
- the roller 9 is a controller 10 assigned, which detects the pressure of the hydraulic medium with a predetermined Setpoint value compares and the contact pressure of the roller 9 to the strand 3 sets 1 according to a setpoint. From the roll 9 ' Speed determined and fed to a controller 10 ', the speed regulates according to a setpoint. About the contact pressure of the roller 9 is a deformation of the strand 3 controllable. After a first one little deformation, the strand 3 reaches a next pair of rollers 12, 12 '.
- This pair of rollers 12, 12 ' also corresponds to the pair of rollers 9, 9 'via adjusting means 11 and their own controllers 13, 13'.
- the roller pairs 9, 9 'and 12, 12' are in the range of Solidification section, i.e. before the solidification point (swamp tip) 14, so that the rollers 9, 9 'and 12, 12' at the same speed operate.
- All relevant data of the respective casting such as steel analysis, steel temperature and casting speed as well as the data recorded via the individual controllers, such as contact pressure of the rollers, Speed of the rollers and current consumption of the roller drives recorded and as Setpoints are returned to the individual controllers.
- the the Setpoints given to individual controllers are thus such Modifiable that with a given final thickness of the strand one possible Even distribution of the deformation work with the least possible
- the individual roles are charged, and the higher one also provides Control the speeds depending on the degree of deformation and the size that on the solidified area and that in the area of Solidification section made deformation. It is possible depending on the final thickness and the initial dimension of the strand Keep marsh tip in a certain area of the facility. Thereby it is possible to create a strand that has a high degree of Has rolling structure.
- the specified regulation also allows the deformation work within the guideway in which the rollers against stops are adjustable and over a solidified area of the strand extend to split.
- the Gauge of the strand can already be achieved with a first pair of rollers.
- the following pairs of rollers in the strand withdrawal direction are then in the sense a coincidence of the speed with this, determining the final dimension Controlled pair of rollers, i.e. kept constant. Should be due to a increased resistance to deformation of the strand, e.g.
- FIG. 3 shows a schematic diagram for the control device Claim 5, which has the advantage that a slip one avoided driven role on the strand and the role by the Control loop is kept in its intended purpose.
- the system is also able to detect deviations from the Intercept roll diameter and an automatic adjustment to a new nominal speed.
- a role that is not in contact with the slab, which is slipping has to run in the limit speed.
- a slipping Roller can cause surface damage on the one hand others it is possible that the re-engaging role briefly accelerates the strand so that the strand is pulled out of the mold. If only you Speeds of three neighboring roles considered, see above can the middle role depending on the degree of deformation Accept the speed of the first or last roll. The speed can never contact the slab provided faster than the last role of the Triple and never slower than the first role of the Triple. A blocking role is in the current limit is running and reported as faulty.
- the Slipping role is not considered by the individual controller as Transport involved detected, but when the speed of the middle role is larger than that of the last role the triple, it can only make contact with the Lost slab, it has slip.
- a slipping role by the speed comparison is recognized, can be reported as faulty, it can also be done by intervening in the controller on the average speed of the group of three to then when contact is restored is to participate in the transport again.
- the employment of the roles or the adjustment of the Roll spacing takes place via hydraulic cylinders.
- the necessary pressure is regulated in a pressure Hydraulic station generated.
- the maximum pressure is only on the strength of the mechanical part of the system certainly.
- a distance measurement can be installed. Just with the help of the path measurements, the Recognize employment and other mistakes.
- the job is controlled by servo valves.
- the distance measurement serves as an actual value transmitter.
- each driven roller via a controller as a speed controller is actively driven.
- the multiple roles assigned higher-level controller has one conventional continuous caster the job, small Compensate for disturbances.
- the mean is taken from the sum of the motor currents of each drive.
- the Deviation of the motor current of each roll from the mean is applied as a correction variable to the setpoint.
- the necessary corrector is only small.
- Correction controller For thin slab casting in the area of deformation with solidified core (casting rolls) Correction controller a much larger one Calculate correction range. Here is with everyone Continuity starting from the last correction value calculated. Since the correction of the speed depends on the difference of the single current to the current average can be very large, the engine can slip (not in contact with the strand) role in progress the limit speed go. These slipping roles are then recognized by the monitoring.
