Automatic kink is that the motor of its upstream stand is turned according to the measurement situation that excess material is formed between two adjacent racks
What speed was automatically adjusted, the excess material of adjacent two frames is introduced to one kink of formation on looper.On this looper,
Existing looper height is measured by corresponding digital loop scanner, and in the operation of rolling, by Siemens S7-
The Based Intelligent Control of 400PLC, makes its measured value be consistent with setting value all the time, so as to reach two adjacent racks between Minimal Tension roll
The purpose of system, in actual use, kink covers incorrect setting high and adjustment can cause workpiece measurement fluctuate and head,
The tail ears or side handles of a utensil are long, reduce the qualification rate of steel rolling.
The content of the invention
In view of this, the application provides a kind of kink set control method high, and high with qualification rate, control is simple excellent
Point.
To solve above technical problem, the technical scheme that the present invention is provided is that a kind of kink covers control method high, rolled piece
Before entering milling train N into the front end of milling train N-1 and the rolled piece, the speed of milling train N drops to setting linear velocity VN, rolled piece nips
After milling train N, loop-rising roll is lifted, and the rolled piece forms kink between the milling train N and the milling train N-1, and control system passes through
The rolled piece basal area F of milling train NNWith the rolled piece basal area F of milling train N-1N-1Obtain parameter RN, the control system is by RNAnd milling train
The setting linear velocity V of NNThe linear velocity V of adjustment milling train N-1N-1, wherein：
Parameter RNSpecific formula it is as follows：
The specific formula of parameter Vn-1 is as follows：
Preferably, the control system is connected with scanner, and the scanner continuously detects the actual height of kink, and will
Testing result is sent to the control system, and the control system prestores the setting height value H of kink, and the control system will
The actual height of kink is compared with setting height value, and the linear velocity V of frame N is adjusted by comparative resultN。
Preferably, the entrance of the frame N is sequentially provided with deflector roll and support roller, setting of the control system according to kink
Height value determines the raising height y for playing set Kun, the setting height value H of the described raising height of set Kun y and the kink
Meet equation below：Y=Hsin x；
Wherein：X is the subtended angle that the loop-rising roll center of circle is formed with deflector roll straight line where circular with horizontal plane.
Preferably, the control system always according to testing result adjust level between the support roller and the deflector roll away from
From until the actual height of the kink meets the setting height value of the kink.
Preferably, the control system is connected with display device, and the display device receives the telecommunications of the control system
Number, and show the parameter RN。
Preferably, the milling train includes vertical mill and horizontal mill, and the vertical mill is spaced with the horizontal mill
Set, the kink is located between two adjacent milling trains.
The application is by monitoring the parameter RN, so as to the change of rolled piece basal area that is monitored at the milling train N with
The change of line speed of milling train N, control system passes through parameter RNLinear velocity to milling train N-1 is adjusted, it is to avoid because milling train N-1's
Linear velocity is too low, so as to cause the actual height of kink too low, make to generate drawing steel rolling between milling train.
Meanwhile, during loop-rising roll excessive height, rolled piece forms prominent curved on loop-rising roll, kink is produced excessive tension force, from
And influence final product quality, the control system in the application determined according to the setting height value of kink it is described rise cover Kun lift height
Degree, it is to avoid above-mentioned situation causes product unqualified or produces piling of steel.
Brief description of the drawings
Fig. 1 is schematic flow sheet of the invention.
Specific embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with the accompanying drawings to the present invention
It is described in further detail.
The milling train includes vertical mill and horizontal mill, the vertical mill and horizontal mill interval setting, and rolled piece enters
Enter and be formed between adjacent milling train kink, the vertical mill include by entrance to export be sequentially provided with deflector roll, support roller,
Set roller and scanner, the scanner are parallel with the high point of the kink, and the milling train is connected with control system.
As shown in figure 1, a kind of kink covers control method high, milling train N is provided with setting linear velocity VN, when rolled piece completely into
When the front end of milling train N-1 and the rolled piece enters milling train N, control system drives the speed of milling train N to drop to setting linear velocity VN,
After rolled piece enters milling train N, the loop-rising roll is lifted, and the rolled piece forms kink between the milling train N and the milling train N-1,
The rolled piece basal area F that control system passes through milling train NNWith the rolled piece basal area F of milling train N-1N-1Obtain parameter RN。
Specifically formula is：
The control system passes through RNWith the setting linear velocity V of milling train NNThe linear velocity V of adjustment milling train N-1N-1,
Specifically formula is：
The entrance of the frame N is sequentially provided with deflector roll and support roller, setting height value of the control system according to kink
The adjustment raising height y for playing set Kun, the described raising height of set Kun y meets such as with the setting height value H of the kink
Lower formula：Y=Hsin x；
Wherein：X is the subtended angle that the loop-rising roll center of circle is formed with deflector roll straight line where circular with horizontal plane.
After rolled piece forms kink between milling train N and milling train N-1, the scanner continuously detects the actual height of kink,
And send to the control system testing result, the control system prestores the setting height value H of kink, the control system
With setting height value be compared the actual height of kink by system, and the linear velocity V of frame N is adjusted by comparative resultN。
The control system adjust horizontal range between the support roller and the deflector roll always according to testing result until
The actual height of the kink meets the setting height value of the kink.
The control system is connected with display device, and the display device receives the electric signal of the control system, and shows
The parameter R is shownN。
The application is by monitoring the parameter RN, so as to the change of rolled piece basal area that is monitored at the milling train N with
The change of line speed of milling train N, control system passes through parameter RNLinear velocity to milling train N-1 is adjusted, it is to avoid because milling train N-1's
Linear velocity is too low, so as to cause the actual height of kink too low, make to generate drawing steel rolling between milling train.
Meanwhile, during loop-rising roll excessive height, rolled piece forms prominent curved on loop-rising roll, kink is produced excessive tension force, from
And influence final product quality, the control system in the application determined according to the setting height value of kink it is described rise cover Kun lift height
Degree, it is to avoid above-mentioned situation causes product unqualified or produces piling of steel.
