The control system realization rolling plate thickness of the present invention described further below control process to thickness of slab:
After steel plate is ready, run the rolling starting the first passage, as the steel band of 3.0mm thickness is produced into 0.38mm
Thickness, then, the first passage, rolling the setting data of thickness before plate is 3.0mm, and after rolling plate, the setting data of thickness is 2.23mm, pressure
Lower rate is 25.6%, controls the thickness of strips after rolling plate by AGC automatic thickness of slab feedback system, work as calibrator in the operation of rolling
When 206 real time datas recording the thickness after rolling plate are more than 2.23mm, then export supercharging order by strip thickness control module 2011
To said two hydraulic cylinder servo valve, making said two hydraulic cylinder strengthen roll-force, ironed strip, when calibrator 206 is surveyed simultaneously
When after must rolling plate, the real time data of thickness is less than 2.23mm, then by strip thickness control module 2011 output decompression order extremely described liquid
Cylinder pressure servo valve, makes described hydraulic cylinder reduce roll-force simultaneously, thickens the thickness of strip.
The control system realization rolling plate thickness of the present invention described further below control process to plate shape:
Plate shape roller instrument 207 is divided into 25 districts, every district 52mm width, and there is pressure in the edge region more than 1/3 in plate face, then this region
Stress is effective；Strip Shape Control typically has three kinds of control methods, level, roller, sub-sectional cooling；Level refers to by plate shape control
Molding block 2013 sends order to hydraulic cylinder servo valve, controls the height position above pushing away hydraulic cylinder 110 of O, D both sides of work roller 109
Putting, generally, the height that said two pushes away hydraulic cylinder 110 is identical, as: when plate shape roller instrument 207 detects whole side, O side
Stress is less, and i.e. plate shape is upwards, represents the thinner than D side of O side pressure, now needs to reduce the height pushing away hydraulic cylinder 110 on O side, accordingly
Increase D side on push away the height of hydraulic cylinder 110；Roller refers to the bending situation controlling work roller 109, as when plate shape roller instrument 207
Detect when the ratio of the pars intermedia dividing potential drop of work roller 109 is relatively thin, the flexibility of work roller 109 need to be reduced；Sub-sectional cooling, 25 regions,
Each region has one group of nozzle to be responsible for spraying cooling, when certain district's plate shape upwards, stress is less, represents that this region work roller 109 is straight
Footpath is relatively big, and now nozzle persistently sprays and cools down.
Automatic strip shape control, is the calculating deviating from value by plate shape, and it is cold to push away hydraulic cylinder 110, roller, segmentation on controlling
But complete.Plate shape deviate from value by plate shape roller instrument 207 survey calculation out.Strip Shape Control module 2013 main
Purpose is that the extension of the various piece of panel is consistent, thus can panel face wave.
Plate-shape standard curve is also referred to as aim curve, i.e. TARGET SHAPE, using it as the target of panel shape, makes to roll
The sheet material of required plate shape precision is obtained during system.So-called on-gauge plate sigmoid curves, sheet material internal stress edge when essence is rolling
The distribution curve of width, it represents the plate shape condition rolling rear sheet material.
And raw material is without production, it is not known that depth information, add the non-intellectual of production.
Such as the raw material with 3.0mm thickness, calibrator 206 record roll before plate the real time data of thickness 2.9mm to 3.05 it
Between time, then data feedback is exported, to main control unit 205, main control unit 205, the life not changing speed by strip thickness control module 2011
Order is to converter, and converter does not change the running of motor, and setting speed rolling pressed by milling train；Such as raw thickness super thick 2% but do not surpass
Thick 5%, when before i.e. calibrator 206 records and rolls plate, the real time data of thickness is more than or equal to 3.06mm but is less than 3.15mm, then plate
Thick control module 2011 is by data feedback to main control unit 205, and main control unit 205 output reduces the order of speed to converter,
Converter adjusts the running of motor, and milling train unit reduction of speed produces；Such as raw thickness super thick 5%, before i.e. calibrator 206 records and rolls plate
When the real time data of thickness is more than 3.15mm, then strip thickness control module 2011 by data feedback to main control unit 205, master control list
Unit 205 output halt command stops the running of motor, then milling train compressor emergency shutdown to converter, converter.This is because, work as raw material
When thickness is 3.15mm, the reduction ratio of the first passage is then 29.2%, and reduction ratio easily causes the most greatly the production accidents such as broken belt.
Compared with prior art, the control method rolling plate thickness of the present invention can monitor the thickness of steel plate in real time, can be at steel
In the case of plate thickness is excessive, can realize making timely automated being decelerated to of milling train stop, it is to avoid steel band causes broken belt because of thickness fluctuation,
Effectively save production cost, protect milling train.During rolling, also the thickness of steel plate and plate shape can be adjusted, improve
The quality of finished product.
The invention is not limited in above-mentioned embodiment, if various changes or modification to the present invention are without departing from the present invention
Spirit and scope, if these are changed and within the scope of modification belongs to claim and the equivalent technologies of the present invention, then this
Bright being also intended to comprises these change and modification.
