Raw hydraulic cylinder drain charge, and rolling torsion is excessive, causes main driving motor to trip.Reduction settings are too small, then it is unnecessary to increase
Rolling pass number, cause energy consumption to increase.Existing process control model system does not possess also to have to be carried out certainly for drafts
The control device of dynamic optimization, all manually adjusts some its by technologist and thinks the drafts of irrational passage, but be based on
At present many factories receive orders be the more specifications of small lot present situation, the rolling procedure table of different product is different, each
The road number of rolling procedure table is several to dozens of again.Therefore, the workload of technologist's regulation drafts is very big, difficult
Exempt from substantial amounts of omission and mistake occur, huge loss is brought to factory.
The content of the invention
It is an object of the invention to provide a kind of control method of reciprocal reversable mill passage load optimal, this method can be with
It is big to solve existing reciprocal reversable mill drafts adjustment workload, substantial amounts of the problem of omitting and be wrong easily occurs.
In order to solve the above problems, the technical solution adopted by the present invention is：This reciprocal reversable mill passage load optimal
Control method comprise the following steps：
A, drafts pre-calculated values are adjusted：When the rolling of one piece of rolled piece of completion, process control model systems inspection, which goes out to exist, stings
Enter failure and successful passage is bitten after it have adjusted drafts, the drafts adjusted value of these passages is recorded, to next piece
Before same specification rolled piece is rolled, the initial depression amount pre-calculated values of these passages are adjusted to the drafts adjusted value, and count
The difference of drafts adjusted value and initial depression amount pre-calculated values is calculated, obtains the offset for optimization；
B, according to mill capacity, drafts pre-calculated values are optimized：The rolling of all rolling passes of the rolled piece of rolling is checked
Load condition, rolling load include roll-force and main transmission electric current；The passage of desired value is not up to actual rolling load, is judged
Whether it is due to that model calculating deviation and not up to desired value occurs, if it is, entering to rolling force model and current model
Row amendment, without being adjusted to the drafts pre-calculated values of these passages；If it is not, then determine whether actually to roll
Whether load processed is due to that the setting of drafts pre-calculated values is too small and not up to desired value, if it is, increasing the passage
Drafts pre-calculated values, rolling force model is substituted into again and is calculated, constantly increases drafts pre-calculated values, then roll-force and electric current
Pre-calculated values also increase, until when precomputation roll-force or precomputation electric current reach desired value, it is estimated to stop increase drafts
Calculation value；The drafts adjusted value of the passage of increase drafts pre-calculated values is calculated, is calculated according to the initial depression amount of these passages
Value, drafts adjusted value and offset, the drafts for the passage for increasing drafts pre-calculated values in this step is redistributed, is obtained
Drafts pre-calculated values after to optimization；
C, subsequent treatment：Total rolling pass number is checked, if total rolling pass number does not change, recovers all pressures being adjusted
Lower amount pre-calculated values are to initial depression amount drafts pre-calculated values, if causing the reduction of total rolling pass number, next time
When calculating rolling procedure table, the drafts pre-calculated values after optimization are performed, finally calculate the total road number of final rolling.
In the technical scheme of the control method of above-mentioned reciprocal reversable mill passage load optimal, more specifically technical scheme is also
Can be：The decision logic for biting failure is：In the case where milling train is in rolling mode, when rolling force sensor detect roll-force by
Drift value increases to more than 300 tons, through being down to drift value from 300 tons again after a while, if the steering of whole process roll
Changed, be then determined as that there occurs bite failure for the passage；Biting successful decision logic is：Rolling die is in milling train
Under formula, when rolling force sensor detects that roll-force increases to more than 300 tons by drift value, by certain time again from 300 tons
Drift value is down to, if the steering of whole process roll does not change, is determined as that the passage bites success.
Further, when judging that the passage bites successfully, check whether the drafts pre-calculated values of the passage have passed through
Adjustment, if it is expected that calculating gap values between rollers and surveying the difference of gap values between rollers more than 1 millimeter, then it is assumed that drafts pre-calculated values are adjusted
It is whole, then the drafts adjusted value is recorded, if without adjustment, any action need not be carried out；When to next piece of same rule
When lattice rolled piece is rolled, are there is biting failure and have adjusted the passage of drafts in these first and is found out, and by these passages
Drafts pre-calculated values be adjusted according to actual value.
Further, it is assumed that the maximum rolling force that milling train allows is Fmax, unit is ton；Actual measurement when rolling certain passage is rolled
Power processed is F, and unit is ton；The precomputation roll-force of the passage is Fset, unit is ton；The maximum electricity for the main transmission that milling train allows
Flow for Amax, unit is ampere；Measured current is A when rolling the passage, and unit is ampere；The precomputation electric current of the passage is
Aset, unit is ampere；Safety coefficient is λ, and safety coefficient λ span is 0.8≤λ≤1；Check that all of the rolled piece roll
The actual rolling load situation of passage processed, works as F<Fmaxλ and A<AmaxDuring λ, then need further to be judged as follows：
(1) judge to survey roll-force and measured current it is less than normal whether be due to that rolling force model and current model calculate and deviation occur
It is caused；When checking Fset- F>200 and Aset- A>When 100, tackle rolling force model and current model is modified, without
Need to be adjusted drafts pre-calculated values；If not caused by model bias, that needs to continue to judge into (2)；
(2) judge survey roll-force and measured current it is less than normal whether be due to reduction settings it is too small caused by；Check whether and deposit
In Fmaxλ-Fset>200 and Amaxλ-Aset>100 situation, if there is the situation, then illustrate to be implicitly present in drafts
The problem of too small is set, now increases the drafts pre-calculated values of the passage, substitutes into roll-force and model and current-mode again
Type is calculated, and constantly increases drafts pre-calculated values, then the pre-calculated values of roll-force and electric current also increase, until Fset=
Fmaxλ or Aset=AmaxDuring λ, stop increase drafts pre-calculated values.
Further, when producing steel plate of the thickness less than 16 millimeters or thickness is less than 20 millimeters of aluminium sheet, latter three
The drafts pre-calculated values of passage are not involved in adjusting.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：Pass through process
The adjustment situation of Controlling model systems inspection drafts, capacity calculation further according to milling train simultaneously optimize rolling procedure table, realized
The optimization of secondary load, during solving reciprocal rolled plate at present, easily there is the problem of omitting and be wrong in drafts adjustment,
Reduce the workload of adjustment drafts.
Embodiment
With reference to embodiment, the invention will be further described：
The control method of the reciprocal reversable mill passage load optimal of the present embodiment comprises the following steps：
Step A, drafts pre-calculated values are adjusted：
When the rolling of one piece of rolled piece of completion, first, process control model systems inspection goes out the rolled piece in the operation of rolling, i.e. institute
Exist in some rolling passes and bite failure and successful passage is bitten after it have adjusted drafts, record the pressure of these passages
Measure adjusted value；The decision logic for biting failure is：In the case where milling train is in rolling mode, when rolling force sensor detects roll-force
More than 300 tons are increased to by drift value, through being down to drift value from 300 tons again after a while, if whole process roll turns
To being changed, then it is determined as that there occurs bite failure for the passage；Biting successful decision logic is：Rolling is in milling train
Under pattern, when rolling force sensor detects that roll-force increases to more than 300 tons by drift value, by certain time again from 300
Ton is down to drift value, if the steering of whole process roll does not change, is determined as that the passage bites success.When judgement should
When passage bites successfully, check whether the initial depression amount pre-calculated values of the passage have passed through the adjustment of technologist, if in advance
Calculate gap values between rollers and survey the difference of gap values between rollers more than 1 millimeter, then it is assumed that initial depression amount pre-calculated values are adjusted, then are remembered
The lower drafts adjusted value of record, if without adjustment, need not carry out any action.Enter when to next piece of same specification rolled piece
During row rolling, these passages for occurring biting failure and have adjusted initial depression amount pre-calculated values by technologist are looked for first
Go out, the drafts of these passages be adjusted according to the drafts adjusted value of technologist, and calculate drafts adjusted value with
The difference of initial depression amount pre-calculated values, obtains the offset for optimization.The related data such as table 1 of specific rolling procedure table
Shown in, it is assumed that the original thickness of ingot casting or blank is 510 millimeters, and the target thickness of required rolling is 37 millimeters.According to biting
The decision logic of failure signal, wherein the 4th passage and the 6th passage there is a situation where to bite failure.Check the 4th passage and the 6th
Whether secondary precomputation gap values between rollers and the difference of actual measurement gap values between rollers are more than 1 millimeter, it can be found that the precomputation gap values between rollers of the 4th passage
1 millimeter is less than with the difference of actual measurement gap values between rollers, and the difference of the precomputation gap values between rollers of the 6th passage and actual measurement gap values between rollers is more than 1
Millimeter, therefore the actual drafts of the 6th passage is recorded, as the drafts pre-calculated values of the passage of rolling procedure table the 6th next time,
That is the drafts pre-calculated values of the 6th passage are adjusted to 41.3 millimeters by 42.7 millimeters.In the calculating subsequently optimized, certain is such as found
Passage has that drafts pre-calculated values are less than normal, then offset compensation is entered, if the drafts of all passages is estimated
Calculation value has reached maximum or the compensated rear maximum reduction pre-calculated values that can allow beyond passage, then needs increase by one
Individual passage completes the rolling of the drafts adjusted value.
Step B, according to mill capacity, drafts pre-calculated values are optimized：
Assuming that the maximum rolling force that milling train allows is Fmax=2500 tons；Actual measurement roll-force when rolling certain passage is F, and unit is
Ton；The precomputation roll-force of the passage is Fset, unit is ton；The maximum current for the main transmission that milling train allows is Amax=2500 peaces
Training；Measured current is A when rolling the passage, and unit is ampere；The precomputation electric current of the passage is Aset, unit is ampere；Safety
Coefficient is λ=0.8.Check that all rolling passes of the rolled piece whether there is actual rolling load (roll-force and main transmission electric current)
The not up to situation of desired value, i.e., with the presence or absence of F<Fmaxλ and A<Amaxλ situation.On inspection, the 1st, 7,8,9,10,
11st, 12,13,14,15,16 passages meet the above situation, it is necessary to further be judged these passages as follows：
(1) judge to survey whether roll-force and measured current (being not up to desired value) less than normal are due to rolling force model and electric current
Model calculating occurs caused by deviation.Check for Fset- F>200 and Aset- A>100 situation, if there is the feelings
Condition, tackles rolling force model and current model is modified, to ensure the accuracy of pre-calculated values, without to initial depression
Amount pre-calculated values are adjusted.If not caused by model bias, that needs to continue to judge into (2).On inspection the 9th,
11st, 13 passages meet the above situation, it is necessary to be modified to the rolling force model and current model of these passages, without right
Initial depression amount pre-calculated values are adjusted.1st, 7,8,10,12,14,15,16 passages need to continue to judge into (2)；
(2) judge survey roll-force and measured current it is less than normal whether be due to drafts pre-calculated values setting it is too small caused by.Inspection
Look into and whether there is Fmaxλ-Fset>200 and Amaxλ-Aset>100 situation, if there is the situation, then illustrate to deposit really
The problem of too small is set in drafts pre-calculated values, now increases the drafts pre-calculated values of the passage, substitutes into rolling again
Power and model and current model are calculated, and constantly increase drafts pre-calculated values, then the pre-calculated values of roll-force and electric current
Increase, until Fset=Fmaxλ or Aset=AmaxUntill λ, i.e. precomputation roll-force or precomputation electric current reaches desired value
When, stop increase drafts pre-calculated values.On inspection, the 12nd, 14,15,16 passages meet the above situation, need to increase 4 roads
Secondary drafts, and the drafts pre-calculated values after increase are substituted into rolling force model and calculated, until Fset=Fmaxλ or
Aset=AmaxUntill λ.
The drafts adjusted value of the passage of increase drafts pre-calculated values is calculated, according to the initial depression gauge of these passages
Calculation value, drafts adjusted value and offset, the drafts for the passage for increasing drafts pre-calculated values in this step is redistributed,
Drafts pre-calculated values after being optimized.It is computed, the drafts pre-calculated values of the 12nd passage are increased to by 17.7 millimeters
28.5 millimeter, the drafts pre-calculated values of the 14th passage increase to 22.3 millimeters by 11.6 millimeters, and the drafts of the 15th passage is pre-
Calculated value increases to 19.5 millimeters by 10.3 millimeters, and the drafts pre-calculated values of the 16th passage increase to 12.8 millis by 5.8 millimeters
Rice.The 6th reduction in pass pre-calculated values are adjusted, and after the drafts of 4 passages of increase, the overall reduction of rolled piece is by 473 millis
Rice increases to 510.7 millimeters, the drafts of 4 passages need to be re-started into distribution.The drafts sum of 4 passages is
45.4 millimeters, firstly, since the drafts of the 12nd passage is no more than 45.4 millimeters, therefore it can be identified as 28.5 millimeters.Make 4 roads
It is remaining unappropriated drafts sum that secondary drafts sum, which subtracts difference obtained by the drafts adjusted value of the 12nd passage, i.e.,
45.4-28.5=16.9 millimeters, consider that the 6th passage has unappropriated 1.4 millimeters of drafts due to biting unsuccessfully, make 16.9+
1.4=18.3 millimeters, because the value is less than the drafts adjusted value of the 14th passage, therefore it can determine that the pressure after the 14th suboptimization
Lower amount pre-calculated values are 18.3 millimeters.Due to being only achieved that original needs 4 by increasing the drafts of the 12nd passage and the 14th passage
The drafts that individual passage could be completed, the drafts pre-calculated values after optimization are as shown in table 1, original to need 16 passages complete
Into rolling, be optimized for 14 passages now, saved 2 passages.
C, subsequent treatment：
By step A and step B, it is possible to the initial depression amount pre-calculated values of wherein some passages are adjusted, by mistake
Process control model system checks whether the reduction for causing total rolling pass number, if total rolling pass number does not change, recovers
All drafts pre-calculated values being adjusted are to initial depression amount pre-calculated values, if causing subtracting for total rolling pass number
It is few, then when calculating rolling procedure table next time, the drafts pre-calculated values after optimization are performed, it is total finally to calculate final rolling
Road number.
When producing steel plate of the thickness less than 16 millimeters, rear three passages are not involved in adjusting.When production thickness is less than 20 millis
During the aluminium sheet of rice, rear three passages are not involved in adjusting.In addition, when producing sheet material finished product, due to be carried out to the precision of thickness
Control, therefore rear three passages are not involved in adjusting.
