Description
Technical field
Coiler pinch-roll is applied to the present invention relates to the hot rolling reeling technique in field of steel production, more particularly to one kind
The means for correcting that can improve coiler pinch-roll tracking accuracy and bearing calibration.
Background technology
At present, in each steel production enterprise, coiling machine is the visual plant of hot rolling line, for by hot-rolled strip
Coil of strip is into coil of strip.Coiling machine is located at after mm finishing mill unit, is last procedure of hot continuous rolling production line, coiling machine is main
Including capital equipments such as roller-way, flipper guide, pinch roll, reel, Wrapping Rolls.Wherein the main of roller-way is responsible for strip
Coiling machine unit is delivered to by mm finishing mill unit.The main function of flipper guide is centering strip.The main function of pinch roll is
Sting the steel stage on head applies certain clamping force to strip, while implementing first time flexural deformation to it；In afterbody volume
The stage is taken to apply stable tension force to strip, to ensure good scroll quality.Wrapping Roll helps to bend strip, and makes
Strip tightly winds coiling.After reel is in strip winding, tension force is applied to it, to ensure that scroll is up-to-standard.
In actual production process, because mm finishing mill unit apart from coiling machine has certain distance.The basis of coiling machine is automatic
Changing computer needs to know when strip after mm finishing mill unit is shut out, reaches coiler pinch-roll, and this is coiling machine
One important component of tracking.Existing technology is：When strip bites the last frame of mm finishing mill unit, finish rolling end frame
Motor rotation-speed measuring device measurement rotating speed be uploaded to finish rolling basic automatization computer.Finish rolling basic automatization is calculated
Machine, which will sting steel signal, roll neck and rotating speed, to be occurred to batching basic automatization computer.Batch basic automatization computer again
According to the position for stinging steel signal, roll neck and rotating speed calculating strip steel head.
Because mm finishing mill unit and coiling machine distance are longer, and strip may be obstructed, play set in the process of running, calculate band
Steel head position is often inaccurate, so coiling machine tracking system also needs to utilize Withdrawal roll pressure fluctuation signal pair
The strip steel head calculated is corrected.When strip steel head hits pinch roll, the pressure-detecting device detection of pinch roll
To Pressure Fluctuation Signal, the position of strip steel head is corrected by the signal, controlled for subsequent Wrapping Roll.
However, above-mentioned production process is only perfect condition, and find that prior art has folder during actual use
The problem of sending roller pressure jitter, it is mainly shown as, after pinch roll uses a period of time, pinch roll
Middle part can wear and tear, now, when strip steel head hits pinch roll, although the pressure-detecting device of pinch roll can be with
Slight pressure oscillation is detected, but pressure can not be reached or more than amplitude limit value, led to not to strip steel head
Position is corrected.
And the pinch roll rear increase laser detector in coiling machine is there are in the prior art come solve can not be to strip
The problem of position on head is corrected, still, by the feedback of field worker, because laser detector is to environment
It is required that it is high, it is difficult in maintenance, and often have water and steam fog in coiling machine, these influence whether accuracy of detection, very
Produced to error signal is caused.Moreover, these are equipped with the coiling machine of laser detector, after production a period of time,
Because working environment is more severe, therefore laser detector also lies substantially in the discarded or discarded state in part, on the contrary
Production and spare parts cost are added, therefore installs laser detection means and nonideal solution additional.
The content of the invention
During in order to solve to cause after the middle part of the pinch roll under prior art is worn and torn strip steel head to hit pinch roll, though
The pressure-detecting device of right pinch roll can detect slight pressure oscillation, but pressure can not be reached or more than limit
Amplitude, the problem of leading to not be corrected the position of strip steel head, and laser detector is installed additional to environmental requirement
Height, the problem of difficult in maintenance.The invention provides a kind of means for correcting of coiler pinch-roll tracking accuracy and correction side
Method, is corrected to the strip steel head position calculated by Withdrawal roll pressure and the change for pinching roller speed, is come with this
The problem of solving Withdrawal roll pressure jitter, reaches the purpose for improving coiling machine tracking accuracy.
A kind of means for correcting of coiler pinch-roll tracking accuracy of the present invention and bearing calibration, it comprises the following steps that institute
State：
A kind of means for correcting of coiler pinch-roll tracking accuracy, including the last frame of strip, mm finishing mill unit and finishing mill

2) signal Credibility judgement is carried out：In order to prevent error signal from causing the tracking correction of mistake, to pinch roll set
The pressure detecting signal and pinch roller speed reduction signal that the Withdrawal roll pressure detection means of part is obtained carry out confidence level and sentenced
Disconnected, it is specifically, when step 1) in the position of strip steel head that calculates whether reach default pinch roll detection model
Enclose in ± a meters, such as reach, then correct system and open, the pressure detecting signal now occurred and pinch roller speed reduction
Signal determining is trusted signal；
3) step 2) in, when Withdrawal roll pressure detection means detects pressure equal to or more than default amplitude limit value P
When, then strip steel head position is corrected；
The step is normal mode of operation when pinch roller assemblies are without exception.
4) step 3) in, such as Withdrawal roll pressure detection means detects pressure less than amplitude limit value P, and pinch now
Roller rotation-speed measuring device sends the pinch roll actual speed detected to basic automatization computer is batched, and batches basis
The pinch roll actual speed received is compared by automated computer with setting speed, and calculates deviation therein,
When deviation is more than default deviation delta S, then strip steel head position is corrected；
5) step 2 described above), step 3) and step 4) in Withdrawal roll pressure detection signal and pinch roller speed
Changing value be all unsatisfactory for preparatory condition, then strip steel head position is not corrected, and directly using the band that calculates
Steel head position.
