Abstract
An installation for operating multiframe roll mill is characterized in that based on the technological relationship of each machine frame, the complete roll mill is progressively constructed in a physically simulated mould, the simulated mould is connected with a central controlling unit which is specially used for regulating and controlling the roll mill, so as to control the selective function of each machine frame.
Description
The present invention relates to be used for the device of operating multi-set of rolling mill, this device both can be used for cold-rolling mill, also can be used for other milling train, such as hot-rolling mill.
Multi-set of rolling mill is reused for after improving when rolling, test-run a machine and optimizing phase, and all there are all difficulties in its operation.On the one hand each frame has and has self rolling mill practice intelligence, is the control device of independent regulation (only giving its higher level's rated value), and this also can dispose regulation and control hardware separately from each frame and obtain proof.Therefore, each frame and operating personnel's thereof coordination, and extremely the realization of the best operation of rolling all needs to have spent corresponding time and expense.On the other hand, the test-run a machine stage is used for operational factor and determines as yet also to cause damage to equipment.
Therefore, testing regulation process in advance on model is highly significant.
So far, only usually developed mechanical sub-model.Mechanical model is spent very much, and can not be connected into a simulator that comprises whole rolling easily.Duplicating of hardware model, it also is very expensive such as one the duplicating of hardware model of the tandem mill of 5,6 frames being arranged.Therefore, all process adjustments all are (promptly being divided into a plurality of different electronic boxs) of disperseing at present, and by many people's tests and put into operation.This just requires participant's close collaboration.
In addition, the producer of mechanical model and user mostly are not same individuals.They also belong to different companies usually.But for the regulation device to oneself is best adjusted, regulate and control expert all is familiar with oneself from mathematics and on the physics simulator (control device) is rather important.This point is not protected toward contact at present.
With regard to the software model (mathematical description of each unit of milling train) that uses so far, they are to use making of the program language that is difficult to understand for mill operators (such as assembler etc.).In addition, these model programs move on special-purpose computer mostly, thus can not with user profile processor compatibility commonly used.
Task of the present invention provides a kind of device that is used for operating multi-set of rolling mill, by this device, be used for the individual feature test, comprise that the expense and the time of the start of optimizing phase and rolling again (after a milling train is improved) all will obviously reduce, simultaneously, also can be in operating process have no dangerous training to operating personnel, and can be under the situation that the milling train unit is not caused any infringement extended function safely.
For this reason, the device that is used for operating multi-set of rolling mill of the present invention has such feature: the technical relation according to each frame constructs whole rolling one by one at a physical analogy model; Described simulation model can be connected to a center control device, this device is exclusively used in the overall technology control to described milling train, and it controls individual feature in each frame or each frame selectively by the control device of milling train or the appropriate section of described simulation model.
Thus, the cramped construction of a far-ranging part of appliance of script becomes possibility rather primely.Like this, expense can reduce by 30%, and the same reduction of the personal expenditures of software development and execution and hardware costs is only about half of.Because simple, being used in combination based on the concentricity control device of simulation model of describing the milling train technical relation with physics method, can pass through the minority personnel, such as usually the simulation of the mechanical process of dynamic relationship being designed all functions and optimizing in comprising the closed control circuit of all control device by a unique expert.Simultaneously, by constantly following test, can realize fast and the design and the driving of the milling train of safety with what simulation model carried out.Reach convenient, the effectively training of producer and operation side personnel thus.By the preliminary test that carries out by means of simulation model, whenever all can carry out safe functioning and expand milling train.In experimental stage, by rolling simulation repeatedly, visual (visualisierung) that can reach equipment operator (rolling personnel) optimizes.Whenever can come the pretest milling train by the operation of extensive simulation.The center control device also is the center of all correlation technique measurement parameters simultaneously.Therefore, can real-time collecting and important measurement parameter and the state of evaluation.This collection (passing through personal computer) compares to the collection of using by so far that system carried out, and expense reduces much and be more real-time.During improved milling train rolling again, its rolling personnel obtain training by simulation model, therefore, at learning phase, although operate miss may occur, can not cause mechanical damage.Operating personnel's learning phase is also very short and effective.The milling train motor, roll gap system and working roll curvature device form as the control device that is provided with self intelligence.Therefore, by a place, promptly only whole rolling mill practice is regulated and influenced by the center control device.

-work roll curvature.
-to the manual correction of mill speed.
The concrete number of above-mentioned part is given by the corresponding units of waiting to operate milling train.
The moved simulation program of simulation model each several part provides following measurement parameter: band steel pulling force, draught pressure, mill speed, main rated value (Leitsollwert), the curvature actual value, thickness deviation, the rectified current of motor current (in the rectifier of motor feed) and hydraulic pressure location adjusting device.
For making these models provide above-mentioned signal to simulation model 2, they mainly need following numerical value and signal: enter the preceding belt steel thickness of first rolling machine frame, the roll gap location (adjusted value) of each frame, the location additional numerical values of roll A side and B side, the speed additional numerical values of each frame, the curvature actual value of each breast roller, the tracking signal of rolled piece position during into and out of each roll gap, and main rated value (LSW) that is to say that greater than the signal of zero (LSW＞0) this device moves.All these signals and numerical value all pass through line 7 and exchange between simulation model 2 and center control device 1.
Fig. 2 is illustrated in the simulation model 2 milling train of simulation, and with one the tandem mill of 4 frames (G1-G4) being arranged here is example, with the principle connection layout of center control device 1, and with the connection layout of the board-like PC13 of plug-in unit that has display 12.
In addition, simulation model 2 also comprises the milling train motor model of frame G1-G4 topping roll.These milling train motor models obtain higher level master's rated value XLSW from model LSW, in addition, they also obtain to be used for the adjustment order Delta V1-Delta V4 of milling train motor rotary speed deviation from band steel tension FZ-Reg, and obtain band steel pulling force actual value XFZ 1/2 and XFZ 3/4 from the band steel pulling force actual value model that is used for band steel pulling force between frame G1 and G2 or G3 and the G4.The milling train motor model provides the corresponding rotary speed actual value XV1-XV4 of the milling train motor of frame G1-G4 to band steel pulling force actual value model and material flow tracker MFV, and motor rotary speed actual value XV1 and the XV4 of frame G1 and G4 are provided to frame G1 and G4 thickness deviation model.
The thickness deviation model of frame G1 and G4 thickness modulator DR1 and the DR4 in center control device 1 provide thickness deviation DeltaH1 and the Delta H4 that draws from motor rotary speed actual value XV1 and XV4.
In center control device 1, thickness modulator DR1 and DR4 are according to the roll gap deviation of frame G1 and G4, by signal Delta WS1 and Delta WS4, with band steel draft regulator FZ-Reg together, frame G1-G4 roll gap rated value adjuster is exerted one's influence, and this rated value adjuster sends roll gap plus definite value Delta WS1 to Delta WS4 to mill model according to the roll gap deviation of frame G1-G4.
In center control device 1, material flow tracker MFV is controlling band steel draft regulator FZ-Reg, roll gap rated value adjuster, frame device G1 and G4 caliper profiler DR1 and DR4, draught pressure adjuster FW-Reg and rated value device W-Bieg, and simulation model 2 interior curvatures are regulated the roll curvature amount value WBieg1-Wbieg4 that model provides frame G1-G4 in this rated value device.These curvatures are regulated the actual value Xbieg1-Xbieg4 that model draws frame G1-G4 roll curvature thus.
Roll gap model not only, band steel pulling force actual value model, main rated value model, frame G1 and G4 thickness deviation model, and curvature regulates model and all provides the simulation value that (as shown in Figure 2) draw by them to the board-like PC13 of plug-in unit, and these simulation numerical value can be seen on display 12 by this computer.The situation that control device 1 each link in center is material flow tracker MFV, band steel draft regulator FZ-Reg, be used for the output parameter of roll gap adjustment and the rated value device that is referred to as the rated value adjuster of frame G1 and the adjustment of G4 thickness, the rated value device W-Bieg that is used for roll curvature and draught pressure adjuster FW-Reg (the draught pressure adjuster provides draught pressure rated value WFW1-WFW4 for frame G1-G4) also is like this.
In order to simulate some special circumstances, can be individual links blanking from physical model.Because the trend correctness and the dynamic relationship of the signal that is produced in simulation model, secondly the calculating of controlling accurately in the study of the Chinese classic in addition comes into one's own.By using the respective actual value of collecting from milling train, being real measured value, the blanking link that replaces simulator 2 is possible.Therefore, can realize from the gradually transition of simulated operation such as training stage the mill personnel to practical operation.
Fig. 3 represents the principle assumption diagram by the milling train motor model simulator of rectifier feed of band transmission adjusters in the simulation model 2 speed regulator of armature supply adjuster (below be equipped with).Milling train motor such as same integrator, therefore, in Fig. 3, the milling train motor that integrator 23 expressions simulated.The output variable of integrator 23 is to also have bar rolling speed to be directly proportional in other words with the rotating speed of milling train motor.The positive input variable of integrator 23 is equivalent to the armature supply (electric work) that the rectifier of milling train motor provides, the negative input signal of integrator 23 be equivalent to the milling train motor be maintenance speed the mechanical power that must finish.If two input signals of integrator 23 are equally big, this just conforms to the state of " all the torque sum equals zero ", and motor just continues with normal speed rotation.If two input signals are different big, this just means and has surplus torque, that is to say that the milling train motor has quickened or slowed down.The acceleration time of integrator 23, (Hochlaufzeit) was equivalent to the acceleration time of milling train motor.
Speed regulator that is equivalent to true motor, and obtained regulation rotating speed rated value WV and be present in the pi regulator 21 of the adjusting deviation between the rotary speed actual value XV of integrator 23 outlets, here be rolling simultaneously and quicken the generator of electric current.Do not design independent acceleration and connect (circuit), load onto but can add without a doubt.For this reason, must provide a signal for faster according to rolling data to rated value device model (referring to accompanying drawing 2).The ratio of pi regulator 21 and integral parameter are equivalent to the numerical value of speed regulator in the interior transmission adjuster of milling train.
At the motor load model of the negative terminal input value D on integrator 23 in Fig. 3, considered that the milling train motor load bearing the situation of deformation of rolled wire moment and rolled piece pulling force moment.Distortion moment is directly proportional with distortion volume (inlet thickness deducts exit thickness and multiply by strip width) and the draught pressure that is produced.The milling train motor loads because of the rolled piece back pull, because of pulling force before the rolled piece unloads.The difference of two pulling force exerts an influence to main shaft as rolled piece moment.Distortion, back pull, these three numerical value of preceding pulling force must add that slope restriction (additiv steilheitsbegrenzt) adds on the motor model afterwards.Must receive load model on the negative input end of integrator 23 by the signal of an employed rolled piece tracking device.At first, load itself must comprise the deformation of rolled wire that does not have back pull.This distortion is according to calculating into and out of the difference of rolled piece thickness (rolled piece mode cross section).A frame advance the rolled piece cross section be exactly previous frame go out the rolled piece cross section.This charging cross section must belong to a rolled piece section.Therefore, rolled piece section tracker must be stored the rolled piece cross-sectional view, and carries (rolled piece segment model) according to bar rolling speed.Draught pressure rises, and perhaps or rather, load has a slope, and this slope can be simulated by a slope limiting unit.If the friction of also additional simulation backing roll just must have a differentiator unit to collect draught pressure and rise, but also get the output signal of this unit of additional input.
Rolled piece pulling force between two frames is exactly the poor integration of instantaneous mass stream that produces between a roll gap.In order between two frames, to produce the rolled piece pulling force, have at least the desired inventory of frame more certainly than what previous frame provided.
By formula:
The He=inlet thickness, the Ha=exit thickness
Ve=rolled piece charging rate, the numerical value that Va=rolled piece discharging speed is calculated are directly to be directly proportional with the rolled piece pulling force.Because the charging rolled piece must stretch again, the rolled piece pulling force that is forming is fed rolled piece again and eliminates.By first approximation, whole situation is equivalent to the combination of an integrator with " off-load process ", and this process depends on the rolled piece band width.One adder can be as the computation model (not drawing here) of simulation rolled piece pulling force, and the moment material flow that this adder is at first calculated in the roll gap is poor.After this material flow assignment by a VZ1 cell processing.VZ1 contains the unit integration and ratio comprehensive function, and it conforms to required analog functuion fully.In addition, bar rolling speed and absolute deformation are used to amplify (uninstall feature), and rolled piece thickness is used to the rise time.
For simulating enterolithic actual influence of roll gap and the dependent interaction in next frame, the rolling rolled piece section of the rolled piece process model input (A: transmission side rolled piece thickness, B: fore side rolled piece thickness) that on purpose draws in accompanying drawing 4 to one, be divided into two shift registers 25,26 according to thickness.The accuracy of simulation depends on the quantity of used memory in the shift register 25,26.The pulse recurrence frequency of each shift register is derived from bar rolling speed.Such as: G1 adjusts to frame, has just produced corresponding rolled piece thickness in the roll gap of frame G1, and this rolled piece thickness changes with certain bar rolling speed VS in the process of going to frame 2.Distance between frame 1 and the frame 2 is m.So, the time from G1 to G2 is during the highest bar rolling speed VS
t1＝m∶VSmax
If shift register 25,26 has such as 22 registers, the rolled piece thickness in time t1 storage must pass through apart from m so, perhaps by all 22 registers send pulse (A ': the transmission side belt steel thickness after the frame distance; B ': the fore side belt steel thickness after the frame distance).In other words, when the highest bar rolling speed VSmax, in time t1:22, the numerical value of being stored is sent to another register by a register.Corresponding commutator pulse is guaranteed by an integrator, import corresponding bar rolling speed VS to this integrator, and its time constant can be adjusted by Tn.What a among Fig. 4 represented shift register 25,26 opens the beginning signal.
Relation between (unillustrated here) roll gap model representation roll gap numerical value and the draught pressure.Draught pressure is produced by the absolute deformation and the relative deformation of the rolled piece with deformation drag.This resistance reduces along with the increase of back pull and preceding pulling force, and decides on bar rolling speed.When the rolled piece top penetrates in roll gap, promptly produce draught pressure and rise.Draught pressure when adjusting roll gap rises and is different from traditional roll location adjustment.Traditional location adjustment forms roll gap because of the adjustment of frame location and spring installation.The roll gap adjustment can be controlled the spacing of working roll axle journal, and makes its maintenance constant.Like this, modulus of elasticity is offseted, thereby does not need to regulate by rolled piece pulling force or thickness again and adjust.
As use the location to regulate model, and a motor location adjusting device and a hydraulic regulating device can be passed through in the location, and perhaps a direct roll gap adjustment device is as prerequisite.In these links any one is all different.Such as: if motor locating device keeps original position during open rolling (Anstechen), roll gap only changes because of the elastic modelling quantity of machine so.And hydraulic regulating device short time when open rolling is separately adjusted to original position again then, but its elastic pulling force is still separately.Separately, and do not rely on elastic modelling quantity theoretically and adjust to the identical opening that rolls during the roll gap adjustment device open rolling.These dependences must be according to the milling train truth at that time model of packing into.
Certainly, the operation of aforementioned multi-set of rolling mill also can be used for singlestandmill.
