Downside on the right side of the strip between shutter 5 and strip left side shutter 6 is equipped with roller-way 15, the roller-way
15 are equipped with the strip 13 of conveying, and the strip 13 drives mobile direction vertical with sliding rail 1 by roller-way 15.
The sliding rail 1 and the sheave are all made of stainless steel material and are made.
The present invention blocks frame air motor instead of conventional hydraulic as power drive using left and right, and hydraulic power drives, by
Big in environment temperature height, steam, to cause the hydraulic cylinder oil degradation of main driving part, leakage, fluctuation of service is caused
Influence to strip quality；It is driven, motor associated materials ageing failure, is unable to satisfy under adverse circumstances normal using motor power
It uses,
Therefore, to guarantee to control precision, using strap brake control form, air motor under the conditions of dying locks radical occlusion device
Stop rapidly.This technological accumulation and inheritance better adaptability, effectively avoids the defect of the prior art.
Aerodynamic brake is pneumatic control compress mode, when motor operations, as shown in figure 4,3. compressed air is filled with by shuttle valve
Brake inner cylinders, cylinder compress brake spring, and air motor works normally；When 1. reversal valve has a power failure, outside is without pressure
Contracting air enters, and non-compressed air (inner air is excluded rapidly by fast-discharge valve EA) in brake cylinder, compressed spring driving is stopped
Vehicle piece brakes motor.
Shutter 5 and strip left side shutter 6, frame, are changed to high-temperature resistant anti-corrosive material, Ke Yida on the right side of the strip
To long-term non-maintaining.
When online running, it is not necessarily to any electric device, original technology can be eliminated because of online electrical equipment environmental suitability
Disabler, maintenance cost height, poor reliability caused by difference.
Working principle: in the prior art, the left part and right part amount of blocking be according to protocol table technique initialization, but strip reality
During the dynamic deflection of border, edge-masking position is remained unchanged, and on the basis of original technology, we pass through finish rolling center line of discharge
Offset data realizes the routines asymmetric movement of two sides edge-masking, as shown in figure 5, firstly, passing through finish rolling center line of discharge measuring device
Detect the disalignment data of strip, ordinate represents strip disalignment amount, and positive and negative offset respectively represents strip
Center line to the right, offset to the left；Then, by the way that finish rolling center line of discharge measuring device to be detected to the disalignment of strip
Data are uploaded to PLC control system, PLC control system by signal be transmitted to it is left and right block frame air motor, it is left and right to block frame gas
Dynamic motor respectively drive left and right driving axis rotation, thus make left and right side edge-masking frame by left and right roller group on the slide rail
Sliding, achievees the effect that left and right side edge-masking frame is individually subjected to displacement；Then, then by left, left side block frame laser
Target measures the relative position of left and right side edge-masking frame respectively, when to reach center line inclined for left and right side edge-masking frame shift length
When shifting amount, signal is fed back into PLC control system, PLC obtains signal and provides instruction, stops the left and right frame air motor that blocks
Movement.
Above step is operated alone by the laser ranging and air motor of two sides, to realize that two sides edge-masking is non-right
Title movement, it is final to realize that the edge actual amount of blocking in strip two sides is consistent, it is inconsistent to be effectively improved the practical amount of blocking in strip two sides
Bring width direction performance is uneven, this action process is that PLC control system according to strip off-centring data correspond to edge screening
Blocking means displacement realizes automatic control, to make on the right side of the strip of edge-masking shutter 6 on the left of shutter 5 and strip
The cooling water that spray equipment sprays down is tilted down by its top steel plate and is drawn to middle part, thus by opposite strip edge
The cooling water in portion 14 drains into the middle part of strip 13, effectively adjusts the temperature on strip width direction, avoids steel edge portion 14 warm
Drop is overrun, and guarantees that strip is cooling uniform.
Laminar cooling water is not recycled using mechanical cooling water, drives strip 13 to move forward by the rotation of roller-way 15, side
The cooling water that shutter 5 and strip left side shutter 6 spray down spray equipment on the right side of the strip that portion is blocked passes through its top
Steel plate is tilted down and is drawn to middle part, so that the cooling water of opposite steel edge portion 14 drained into the middle part of strip 13, effectively
The temperature on strip width direction is adjusted, 14 temperature drop of steel edge portion is avoided to overrun, guarantees that strip is cooling uniform.
It is described above by example, but the present invention is not limited to particular forms disclosed above, it should be understood that, this field
All deformations or replacement of the technical staff to inventive technique scheme, all without departing from the essence and protection of technical solution of the present invention
Range.
