The rolling-mill housing of this operation of rolling of-execution is adjusted automatically according to the rolling-mill housing setting valve that transmits, and according to the rolling-mill housing setting valve rolled strip of measuring.
The invention still further relates to a kind of data medium, store a computer program that is used to implement described method on the described data medium.In addition, the invention still further relates to a kind of computer, it has one and stores the mass storage of computer program, thereby can implement described method of operating by calling in described computer program.In addition, the invention still further relates to a kind ofly by described computer-controlled milling train, it has at least one and is used for rolling-mill housing at the plural number time rolling band of the operation of rolling.At last, the invention still further relates to a kind of in described milling train the rolling band that forms, wherein, described milling train carries out work by described method of operating in the process of rolling described band.
Background technology
The method of operating that is used for the milling train of the described type of introductory song is widely known by the people.It is used for carrying out pre-adjustment more and/or keeps setting valve or with prescribed manner setting valve is adjusted in the strip-rolling back that finishes before a band enters milling train.The mill model that computer is used for measuring the rolling-mill housing setting valve is not to be one to measure and follow the tracks of the simple controllers of control variables according to rated value and actual value in close loop control circuit.Or rather, the effect of mill model is the mensuration of rated capacity.Only rolling-mill housing is carried out still closed-loop control (auxiliary) of open loop control according to the rated capacity of measuring subsequently, this point is very unimportant.
Band passes rolling-mill housing or extracts out from rolling-mill housing is rolled strip, particularly a critical process during hot-strip.Special in the process of rolling thin strip, lateral displacement might take place in band head and/or afterbody.This is under extreme case even may cause band to rupture in some operations of rolling.Therefore, be necessary to adopt a kind of can guarantee that band does not take place or only take place can unheeded slight lateral displacement the strip-rolling method.
In the prior art, can the transversely symmetrical tension distribution of band be very important with milling train center line symmetry for the band passage.To this, known solution is to measure this tension distribution by special deflection cylinder (or otherwise).For example follow the tracks of tension distribution, make its become symmetry or maintenance symmetry by the deflection of working roll.Wherein, carry out this tracking with manual type or in a close loop control circuit.
Tension distribution detects and requires band is what tighten in the front and/or the back of the rolling-mill housing that it is rolled.Otherwise, just can not produce tension force in the band.Therefore, the processing mode of prior art only has limited applicability, particularly when band head and band afterbody pass milling train, because in both cases, band can only one-sidedly be tightened, just only tighten, perhaps only tighten, and can't tighten in the front and back of described frame simultaneously in the back of described rolling-mill housing in the front of described rolling-mill housing.Control loop is at least one-sided open loop.
Summary of the invention
The purpose of this invention is to provide a kind of method of operating of a milling train and product correspondingly of being used for, can be rolled band head and band afterbody, it is not taken place or negligible slight lateral displacement only takes place by means of described method.
The purpose of method of operating realizes by following scheme:
-computer calculates the band expection of this operation of rolling and derives wedge shape in the scope of the mill model that is applicable to each operation of rolling;
-one tape deck at least one record position of milling train, write down one with the actual derivation wedge shape relevant measurand of band on this record position, and it is transferred to computer; And
-computer is derived wedge shape according to the expection on the described record position and the measurand that writes down on described record position is regulated mill model.
Because in the case, can realize that especially band ground improves mill model one by one, and then the rolling-mill housing setting valve after improving is measured.
The purpose of relevant data carrier, computer, milling train and band is reached by the described device of claim 13 to 16.
Described milling train can only have a single rolling-mill housing, and can be rolled described band with reversible manner.But described milling train is configured as multi-set of rolling mill usually.In the case, each operation of rolling is carried out by different rolling-mill housing.
Import wedge shape if one of them input parameter of band is an expection of this operation of rolling, and computer derives wedge shape to rolling-mill housing setting valve and expection in regular turn and measures, described method of operating just especially accurately, reliable.Because in the case, the derivation wedge shape of an operation of rolling is consistent with the importing wedge shape of next operation of rolling.
The important input parameter of band refers to the hardness of band especially.
The rolling-mill housing setting valve is specific to comprise that a roll-force of a rolling gap wedge shape, a general rolling force and/or each rolling-mill housing is poor.
If computer in the measurement range of wedge shape is derived in the expection of an operation of rolling, with the derivation wedge shape of before the operation of rolling as Consideration, computer just can measure relevant before the wedge shape summary of all operations of rolling.Can make described method of operating obtain higher accuracy whereby.
Usually in the end an operation of rolling finishes the described measurand of back record.But also can in the end carry out record to it before an operation of rolling.
For example the Tension Difference by so-called differential tension kink or strap tension measuring roller mensuration can be used as described measurand.Also can write down described measurand by measuring device for testing alignment or strip edge measurement mechanism.Method is especially reliably, measures the rolling-mill housing setting valve at least one operation of rolling, makes band have the limit wave of band edge wave wave amplitude after this operation of rolling, measures described measurand according to limit wave wave amplitude again.But the difference of limit wave wave amplitude is in particular a valid metric Tension Difference and is present in the yardstick of the derivation wedge shape in the band.
If in the end write down described measurand before operation of rolling, and at the latest when carrying out last operation of rolling from the flat limit of band central roll wave, described last processing method is with regard to advantageous particularly.
As possibility, also can measure described measurand by the automated optical analysis is carried out in the position of the position at the position of strip edge, band center and/or band plane center of gravity.Can use the digit optical image analytical method especially at this.
When being in tension-free state, just implements band method of operating of the present invention for specific.Because when band is loaded with tension force, there is an operational close loop control circuit, in the case, can guarantee band is carried out normal transverse guidance by other modes.

The specific embodiment
As shown in Figure 1, a milling train has a plurality of rolling-mill housing 1 to 6.Wherein, Fig. 1 has shown a milling train with six rolling-mill housing 1 to 6 with exemplary forms.But the quantity of rolling-mill housing 1 to 6 also can be greater than or less than six.
A rolling band 7 in the rolling-mill housing 1 to 6 of milling train.Band 7 is rolled in a plurality of operations of rolling, and wherein, each operation of rolling is carried out by rolling-mill housing different in the milling train 1 to 6.
Described milling train is by a master computer 8 controls.For this reason, master computer 8 has a mass storage 9 that stores computer program 10.Computer program 10 is just finished, and be stored on the data medium 11 with the form that (special) machine readable is got in advance.For example CD-ROM is a suitable data carrier 11.Computer program 10 is by data medium 11--or for example pass through the internet--be transferred to master computer 8.
After for example calling in computer program 10 by a user 12 inputs one corresponding call instruction, master computer 8 can be controlled described milling train in a mode that hereinafter will describe in detail by computer program 10 according to the design of program.
For band 7 is rolled, band head 13 is little by little penetrated in each rolling-mill housing 1 to 6.In each rolling-mill housing 1 to 6, band 7 is rolled subsequently.From each rolling-mill housing 1 to 6, extract band afterbody 14 at last again out.Wherein, the operation of rolling of band 7 in each rolling-mill housing 1 to 6 all starts from band head 13 and penetrates each rolling-mill housing 1 to 6, and continues to band afterbody 14 and detached till each rolling-mill housing 1 to 6.
Between band 7 is tightened in wherein two rolling-mill housing in the rolling-mill housing 1 to 6, for example be tightened in rolling-mill housing 2 as shown in Figure 2 between 5 the time, can there be a tension force Z in the band 7.For guaranteeing that band 7 passes the center line 15 of milling train symmetrically, can be to this tension force Z, the distribution in bandwidth b scope is write down and is exerted one's influence to this tension force Z more precisely.But band head 13, just one of them rolling-mill housing from rolling-mill housing 1 to 6 is come out in (according to Figure 2 shows that rolling-mill housing 5) but the strip sections that do not enter the next rolling-mill housing (according to Figure 2 shows that rolling-mill housing 6) in the rolling-mill housing 1 to 6 as yet when coming out from rolling-mill housing 5, is in tension-free state.In the case, if band 7 is derived in rolling-mill housing 1 to 6 and is one in that rolling-mill housing of band head 13 and derives wedge shape, just wherein a side is thicker than opposite side (referring to Fig. 3), and band head 13 will be to a side generation lateral shift.Fig. 2 has carried out illustrating (and for diagram reason exaggerate to some extent) in schematic form to this.
Band afterbody 14 just need enter one of them rolling-mill housing (according to Figure 2 shows that rolling-mill housing 2) in the rolling-mill housing 1 to 6 but the strip sections of having come out from previous rolling-mill housing (according to Figure 2 shows that rolling-mill housing 1) also is in tension-free state when entering aforesaid rolling-mill housing 2.In the case, derive wedge shape if band 7 is one in rolling-mill housing 2, band afterbody 14 will be to a side generation lateral shift.Fig. 2 has also carried out illustrating (and for diagram reason exaggerate to some extent) in schematic form to this.
For avoiding band head 13 and/or band afterbody 14 that this skew takes place, can implement a kind of method of operating that is used for described milling train that hereinafter will describe in detail by master computer 8.
According to shown in Figure 4, in described method of operating scope, in step S1, transmit input parameter H, E, PB earlier to master computer 8.Input parameter H, the E of band 7, PB at first comprise the hardness H of band 7.In addition, these input parameters also enter the importing wedge shape E that each rolling-mill housing was presented at 1 to 6 o'clock particularly including band 7.At last, these input parameters also comprise other parameter PB, for example the temperature of bandwidth b, band 7, thickness, boot speed or the like.
Master computer 8 is applicable to that one input parameter H, E, the PB by a mill model 16 and band 7 is that first operation of rolling is measured rolling-mill housing setting valve K, FG, FD among the step S2 of first operation of rolling.Rolling-mill housing setting valve K, FG, the FD that measures comprise a rolling gap wedge shape K, be applicable to each rolling-mill housing 1 to 6 and the corresponding operation of rolling thereof general rolling force FG, with a roll-force difference FD who is applicable to each operation of rolling.In addition, master computer 8 also is that first operation of rolling is measured the expection derivation wedge shape A that band 7 is presented in step S2 in this operation of rolling.
The derivation wedge shape A of first operation of rolling is consistent with the importing wedge shape E of an expection of next operation of rolling.Whether therefore, master computer 8 can be checked in step S3, also have other operations of rolling to need to carry out.If the way it goes for situation, master computer will will be derived the expection importing wedge shape E of wedge shape A as the next operation of rolling by the expection of its mensuration in step S4, lay equal stress on and newly transmit back mill model 16.In case of necessity, master computer also can be made amendment by all the other Parameter H, the PB to band 7 in step S4.Master computer 8 by this method by mill model 16 in regular turn for second, third etc. the operation of rolling measure the derivation wedge shape A of corresponding rolling-mill housing setting valve K, FG, FD and expection.Last result is, master computer 8 is derived in the measurement range of wedge shape A in the expection of an operation of rolling, wedge shape A derived in the expection of before the operation of rolling take into account.
Master computer 8 is transferred to the rolling-mill housing 1 to 6 of carrying out the operation of rolling with rolling-mill housing setting valve K, FG, the FD that measures in step S5.Each rolling-mill housing 1 to 6 is adjusted automatically according to the rolling-mill housing setting valve K, FG, the FD that transmit, thereby can carry out the operation of rolling that it is assigned with, and according to the rolling-mill housing setting valve K, FG, the FD that measure band 7 is rolled.
On at least one record position of milling train, be furnished with a tape deck 17.According to shown in Figure 1, all there is corresponding tape deck 17 in the front and back of each rolling-mill housing 1 to 6.The tape deck 17 actual wedge shape measurand Ms of record band 7 on each record position.Therefore, tape deck 17 records is the actual importing wedge shape and the derivation wedge shape of the band 7 on the record position.Tape deck is transferred to master computer 8 with these measurands M, and master computer 8 receives these measurands in step S6.
Master computer 8 is transferred to the adjusting device 18 that is implemented in master computer 8 inside, is used for mill model 16 with the measurand M of record in step S7.In addition, the derivation wedge shape A of expection also is transferred to adjusting device 18 in step S7.By means of adjusting device 18, the measurand M that master computer 8 can be derived wedge shape A and write down on record position according to the expection on the record position in step S8, mensuration is used for the corrected value KW of mill model 16, and whereby mill model 16 is regulated.Wherein, also can in adjusting device 18, derive wedge shape A and measure corresponding expection measurand according to expection, perhaps in contrast, according to the corresponding actual derivation wedge shape of measurand M mensuration of physical record.All can be in adjusting device 18 under two kinds of situations in correspondence with each other amount be compared.
By method of the present invention the mill model 16 and the actual performance of milling train are complementary, thereby can progressively improve pre-adjustment each rolling-mill housing 1 to 6.
Hereinafter will get in touch Fig. 6 is elaborated for example to the method that writes down measurand M.According to shown in Figure 6, master computer 8 is measured its rolling-mill housing setting valve K, FG, FD at least one operation of rolling (or being corresponding rolling-mill housing 1 to 6), make band 7 after this operation of rolling or in this rolling-mill housing 1 to 6 back, have limit wave 19,19 '.Limit wave 19,19 ' have limit wave wave amplitude h, h '.The lateral edge 20,20 of limit wave 19,19 when band head 13 is derived ' be formed on band 7 ' on.The limit wave remains to band 7 always and enters next rolling-mill housing 1 to 6 and be loaded till the tension force Z.Similar process also can take place in band afterbody 14 when each rolling-mill housing 1 is come out to 6.Wave amplitude h, h ' are by tape deck 17 records.Wave amplitude h, h ' (have symbol in the case! ) difference is corresponding to measurand M, this measurand M is relevant with importing or the derivation wedge shape of band 7 on each record position.
Above getting in touch the method for Fig. 6 explanation specific is not in the end to implement on a rolling-mill housing 6, but before this, enforcement on penult rolling-mill housing 5 at the latest just.Because so could be at the latest in the end in operation of rolling the limit wave 19,19 in (or in the end a rolling-mill housing 6 on) rolled strip 7 '.In the case, the record nature of measurand M is an operation of rolling in the end, promptly carries out between penult and last rolling- mill housing 5,6 at the latest.
Naturally also can in the end write down measurand M after an operation of rolling end in principle.Then be necessary for limit wave 19,19 ' determine tolerance in the case, or otherwise measure and derive wedge shape.
When needs are otherwise measured the derivation wedge shape, for example can use hereinafter and will get in touch the method that Fig. 7 is described in detail.
According to shown in Figure 7, tape deck 17 is above band 7 and towards the video camera or the suchlike object of described band 7.When band head 13 and band afterbody 14 were positioned at tape deck 17 belows, tape deck 17 can production one images and with its digitlization.Digitized image is transferred to master computer 8, and master computer 8 is analyzed it automatically by known optical analysis method.For example can carry out marginal test.In the case can according to strip edge 20,20 ' position finding measurand M.
As possibility, also can measure the plane center of gravity 21 that all belong to the pixel of band head 13 or band afterbody 14, and measure measurand M in view of the above.Also can measure the position at band center 22, and measure measurand M in view of the above.
Method of operating of the present invention mentioned above can be implemented in principle incessantly, that is to say, also can implement even be tightened between the rolling-mill housing 1 to 6 and be loaded with under the situation of tension force Z at band 7.But according to shown in Figure 4, specific in step S9 at each record position determine whether to exist on this position band 7 with and whether be in tension-free state.Have only in the case and could be arranged in the rolling-mill housing 1 to 6 of each record position front and control with respect to band head 13 specific by method of operating of the present invention with respect to the rolling-mill housing 1 to 6 that band afterbody 14 is arranged in each record position back.Otherwise just carry out a traditional tension force control (step S10).
