- a thickness wedge as used for example in semi-endless rolling at finished strip thicknesses below 1 mm.
- FIG. 1 shows a plant for the production of metal strip 6, which includes a roughing 2, a finishing train 3 and a cooling section 4. Such systems are typical for the steel and metal industry. Behind the cooling section 4, a reel device 5 is arranged. From her is rolled down in the streets 2 and 3 preferably hot rolled and cooled in the cooling section 4 metal strip 6. The streets 2 and 3, a band source 1 is arranged upstream, which are heated, for example, as a furnace in the metal slabs, or, for example, as a continuous casting, in the metal strip 6 is generated is formed.
- the metal strip 6 is made of aluminum or steel, for example.
- the system and in particular the roads 2, 3 and the cooling section 4 and the at least one reel device 5 are controlled by means of a control method which is carried out by a computing device 13.
- the computing device 13 is coupled with the individual components 1 to 5 of the plant for steel or aluminum production control technology.
- the computing device 13 is programmed with a computer program designed as a control program, based on which it carries out the inventive method for controlling or regulating the temperature of the metal strip 6.
- the metal strip or slab 6 leaves the strip source 1 and is then first rolled in the roughing train 2 to an input thickness for the finishing train 3. Within the finishing train, the belt 6 is then rolled by means of the rolling stands 3 'to its final thickness. The subsequent cooling section 4 cools the belt 6 to a predetermined reel temperature.
- FIG. 2 represents the finishing train 3 with its rolling stands 3 'closer and illustrates the inventive model-predictive control of the finishing train.
- the contact times of the hot metal strip 6 with the relatively cold work rolls of the rolling stands 3 'and the inter-frame cooling devices 7 are the most important influencing factors on the temperature of the metal strip 6.
- the actuators of the control of the strip temperature in the finishing train are accordingly the mass flow 16 and the coolant flow 8.
- FIG. 2 For ease of explanation of the embodiment, two band points P 0 , P 1 of the metal strip 6 are exemplified.
- the finishing train 3 is limited by its beginning x A and its end x E.
- the system dynamics in the finishing train 3 is characterized in terms of Temperatur. trim relatively large dead times 105.
- the influence of a change in the coolant flow 8 to the temperature at the end x A of the finishing train 3 can only be observed when the first belt point P 0 , P 1, which was influenced by this change, leaves the last rolling stand 3 '.
- the strip temperature control 17 is designed as a model-predictive control.
- the computing device 13 for controlling the plant of the steel industry and in particular for controlling the finishing train 3 has a belt temperature model 12 and a belt temperature control 17.
- the belt temperature model 12 and the belt temperature control 17 preferably operate cyclically in control steps.
- the strip temperature control 17 has a control device 14 which controls or regulates the coolant flow 8 of the intermediate-frame cooling devices 7 and the mass flow 16 of the metal strip 6, that is, in particular its speed v.
- the control device 14 is preceded by a linearized model 15, which is processed by means of a quadratic programming.
- the online monitor 9 uses a model for determining the current strip temperature and preferably the phase state of the metal strip 6 within the finishing train 3.
- the module 12 for online determination of the strip temperature therefore has a not shown in detail in the drawing belt temperature model.
- the band temperature model makes it possible, for example, to predict the final temperature of band points P 0 , P 1 , ie in particular the temperature of the band points PO, P1, at location x E. Based on this, a linearized model 15 is created, which determines the strip temperature for an operating point of the finishing train 3 for a given change in the coolant flow 8 and / or given change in the mass flow 16.
- new correction values for coolant 8 and mass flow 16 are determined, taking into account setpoint values for strip intermediate temperatures, preferably within the finishing train, or given setpoint values for the final temperature of the strip 6 in the finishing train 3 become.
- the linearization of the belt temperature model results in a quadratic programming problem that can be solved sufficiently fast for on-line control of the belt temperature.
- the purpose of the online monitor 9 is to change the current state, i. In particular, all the intermediate temperatures required for the control or regulation of the metal strip 6 of the finishing train 3 to determine.
- the data 102 present at the output of the online monitor 9 preferably also include real-time model corrections.
- Tape data 101 actually measured in the finishing line and in particular temperatures may not always be present and as a rule only at a few specific locations, sometimes only at the locations x A and x E.
- the online adaptation 10 uses data 102 calculated by the online monitor 9, in particular temperatures determined by the online monitor 9, and preferably measured temperatures 101.
- correction factors are determined, which are used in particular for the correction of model errors in the online monitor 9.
- actually measured temperatures 101 are compared with calculated temperatures 102.
- the online adaptation 10 is coupled both to the online monitor 9 and to the module 11 for the prediction of the temperature of selected band points.
- data originating from the output side of the online adaptation 10 is present at the input side of the module 11 for prediction of the strip temperature.
- the module 11 can further process data determined by the online monitor 9.
- the belt temperature calculated by the module 11 is forwarded to the belt temperature control 17.
- the belt temperature prediction module 11 also uses the belt temperature model of the belt temperature online module 12.
- Input variables of the strip temperature control 17 or of the linearized model 15 are the actual temperature profile determined by the strip temperature model and a predetermined target temperature profile.
- the desired temperature profile is specified depending on the type of installation, the operating mode, the respective job and the desired properties of the metal strip 6.
- the belt temperature control 17 uses input data 103 calculated by the belt temperature model 12. In this case, control specifications can be used particularly flexibly, since the online monitor 9 can determine any intermediate temperature of the belt 6 within the finishing train 3, even if there are no corresponding measured values.
- FIG. 3 schematically illustrates problems relevant to model-predictive control, such as arise when metal is to be rolled in ferrite phase state.
- T d 2 at the end X E of the finishing train 3 is preferably used further temperature setpoints T d 0 , T d 1 within the finishing mill 3. If, for example, the rolling operations of the two first rolling stands 3 'of the finishing train 3 in Austenite area, the other rolling operations, ie the rolling operations of the downstream rolling stands 3 ', but carried out in the ferrite range, you need at least three as in FIG. 3 shown target temperatures T d 0 , T d 1 , T d 2nd
- the first setpoint temperature T d 0 after the second rolling stand is to ensure that the temperature of the rolling operations in the first two rolling stands is above the transition temperature between the phase state areas.
- the second temperature setpoint T d 1 is to ensure the phase transition before the third rolling stand of the finishing train 3. If possible, a final temperature T d 2 at the end X E of the finishing train 3 should be maintained.
- the belt temperature control 17 can also respond to short-term temperature fluctuations, which are caused for example by the oven automation. However, this is preferably done by changing the coolant flow 8, and not by changing the belt speed v or the mass flow 16. Short-term temperature fluctuations, for example, local unevenness or folds of the metal strip 6 condition.
- a coolant flow Q 0 , Q 1 or Q 2 collectively referred to as 8 causes, as far as possible from the technical limits of the inter-frame cooling devices 7, which are preferably designed as coolant or water valves 7 , lies away.
- the greatest possible freedom is achieved at the inter-frame cooling devices 7 to later, ie in subsequent control steps, to be able to respond to short-term temperature fluctuations.
- the coolant flow Q 0 , Q 1 , Q 2 of a valve 7 can only be changed at a speed which corresponds to the dynamics of the respective valve 7 and must not outside technically conditioned minimum Q. max i or maximum values Q max i are.
- the mass flow 16 must also be within technical limits, which are determined in particular by a maximum or minimum speed of the metal strip when leaving the finishing train 3. With regard to the mass flow, a lower and an upper limit of the acceleration a of the metal strip 6 must also be taken into account.
- a prediction temperature T j k for given coolant flow 8 and mass flow 16 and for an adaptation coefficient given for the corresponding control step are calculated with the aid of the belt temperature model.
- the adaptation coefficient is preferably frozen.
- the current coolant flow 8 and the current mass flow 16 are set as the operating point.
- the new forecast temperature T ⁇ k j can then be expressed as T k j + ⁇ ⁇ T k j .
- ⁇ ⁇ T k j ⁇ ⁇ T k j ⁇ ⁇ ⁇ u i j . ⁇ ⁇ u i j + 1 j . ... ⁇ ⁇ u j kj j . ⁇ ⁇ a . ⁇ ⁇ s ,
- the band temperature is predicted so far into the future until a band point P 0 reaches the last temperature setpoint T d 2 .
- this is at the end x E of the finishing train 3, where preferably a not shown in detail in the drawing pyrometer measures the actual temperature of the metal strip 6.
- the model-predictive prediction always takes place for individual control steps .DELTA.t.
- FIGS. 4 and 5 illustrate the different setting horizon for the coolant flow (see FIG. 4 ) and the mass flow (see FIG. 5 ).
- the abscissa represents a time axis.
- the mass flow 16 is preferably influenced by the belt speed v, wherein the control horizon is preferably limited to a single control step. Subsequently, offset ⁇ s and acceleration change ⁇ a are preferably assumed to be constant (see FIG. 5 ). On the other hand, short-term temperature fluctuations are preferably influenced by the coolant flow Q j . For this purpose, temperature prediction values are preferably used for band points P j , which lie in front of the corresponding intermediate-frame cooling device 7 in the mass flow direction, so that the band points P j reach the corresponding intermediate-frame cooling device only after the dead time 105 of the corresponding valve 7 plus the computing time has expired ,
- Minimizing the equation (II) taking into account the corresponding control limits, especially those mentioned above, means solving a problem of non-linear programming, which is usually extremely computationally intensive and needs to be accelerated in order to be on-line.
- Control steps .DELTA.t can take place according to the invention, for example, every 200 milliseconds.
- Q i j act ⁇ S ⁇ k j T k 0 ⁇
- a act ⁇ S ⁇ k j T k 0 ⁇
- f is a scalar
- H a symmetric, positive semidefinite NxN matrix, which is positive definite, if the positive parameters ⁇ , ⁇ , and ⁇ are chosen to be sufficiently large.
- the remaining variables are n-dimensional column vectors.
- the inequality (IX) is to be understood component by component.
- an active set strategy is preferably used.
- travel diagrams for the rolling speed v and / or for the water ramps or coolant ramps of the interstand cooling (7) are particularly advantageously calculated and maintained with particularly high accuracy.
- a flexible control method which is also applicable to other parts of the plant, such as e.g. in particular the roughing 2 or the cooling section 4, can be used.
- a more than one part of the system 1 to 5 cross-application of the invention is possible.
- Particularly advantageous is the use of the invention in two-phase rolling and driving a thickness wedge during the rolling of a semi-endless slab.
