Description
Technical field
The present invention relates to a kind of means for correcting and bearing calibration more particularly to a kind of heat applied in field of steel production
Roll the complex correction device that can improve coiling machine tracking accuracy and complex correction method of coiling technique.
Background technique
Currently, coiling machine is the important equipment of the hot rolling line of each steel manufacturer, it is used for hot-rolled strip steel winding
At coil of strip.It is last procedure of hot continuous rolling production line after coiling machine is located at mm finishing mill unit.Coiling machine mainly include roller-way,
The capital equipments such as flipper guide, pinch roller, reel, Wrapping Roll.Wherein strip is delivered to by being mainly responsible for for roller-way by mm finishing mill unit
Batch unit.The main function of flipper guide is centering strip.The main function of pinch roller is to sting the steel stage on head to apply strip
Add certain clamping force, while implementing first time bending deformation to it；In tail portion, coil ing one applies stable tension to strip,
To guarantee good scroll quality.Wrapping Roll help is bent strip, and strip is made tightly to wind coiling.Reel is wound in strip
After upper, tension is applied to it, to ensure that scroll is up-to-standard.
Since mm finishing mill unit has certain distance apart from coiling machine.So the basic automatization computer needs of coiling machine are known
After strip is shut out by mm finishing mill unit, when coiler pinch-roll is reached, this is an important composition portion of coiling machine tracking
Point.
Existing technology is when strip bites mm finishing mill unit end rack, and the rotation-speed measuring device of the motor of finish rolling end rack is surveyed
Amount revolving speed is uploaded to finish rolling basic automatization computer.Finish rolling basic automatization computer will sting steel signal, roller diameter and revolving speed again
It is sent to and batches basic automatization computer.Finally, batch basic automatization computer according to acquisition sting steel signal, roller diameter and
The position of revolving speed calculating strip steel head.
And since mm finishing mill unit and coiling machine distance are longer, and strip may be obstructed in the process of running, play set, calculate band
Steel head position is often inaccuracy, so coiling machine tracking system is also needed using Withdrawal roll pressure fluctuation signal to calculating
Strip steel head out is corrected.When strip steel head hits pinch roller, pressure that the pressure-detecting device of pinch roller detects
Fluctuation signal is corrected by position of the signal to strip steel head.
However, field worker is fed back in the actual production process, finding the prior art in use, there are pinches
The problem of roller pressure jitter, the main reason is that middle part can be worn when pinch roller is using after a period of time,
When strip steel head hits pinch roller, although the pressure-detecting device of pinch roller can detecte slight pressure oscillation, pressure
It cannot reach or be greater than amplitude limit value P, also the position of strip steel head can not be just corrected.
Summary of the invention
In order to solve present in the above-mentioned prior art after pinch roller is worn using a period of time, strip steel head
When hitting pinch roller, although the pressure-detecting device of pinch roller can detecte slight pressure oscillation, pressure cannot reach
Or it is greater than amplitude limit value P, the problem of can not being corrected to the position of strip steel head.The present invention provides a kind of raising coiling machines
The complex correction device and complex correction method of tracking accuracy, using signals such as temperature, laser, Withdrawal roll pressures to strip tracking
Complex correction is carried out, on the basis of calculating strip steel head position, is filled by temperature-detecting device, laser aid and pressure detecting
It sets and calculated strip steel head is corrected, with this to solve the problems, such as Withdrawal roll pressure jitter, reach to improve and roll up
