Cheng Shisi passage；The top links of No.1 loop trolley 41 have steel wire rope 91 to pass through fixed pulley 61, master winch 81 and roller 71
Traction realizes raising and lowering, tightens up strip 1.After strip 1 is by No.1 loop trolley 41, then by slewing rollers 22 into No. two
Loop trolley 42, the same manner first pass through 14 roads of seven top rollers 53 and the formation of six roots of sensation bottom roller 33 on No. two loop trolleys 42
It is secondary；No. two top links of loop trolley 42 have steel wire rope 92 to be realized by the traction of fixed pulley 62, master winch 82 and roller 72
Rise and decline, tighten up strip 1.
A kind of structural representation for tinuous production vertical loop tension control system as shown in Figure 1, one includes
Selection control 111, the setting value 103 of kink strip speed are inputted in selection control 111, when the thickness of strip 1≤
During 1.6mm, selection control 111 connects former function control block (FCB) 107, the former function control by thickness≤1.6mm branch roads 105
Block 107 inputs kink region tension variation value 101 and kink strip speed actual value 102, passes through former function control block (FCB) 107
Output master winch regulating command 109 and bottom roller regulating command 110 are calculated, the master winch regulating command 109 and bottom roller regulation refer to
110 are made by the first master winch of Frequency Converter Control kink 81, the second master winch of kink 82 and the first bottom roller of kink 31, kink second
The rotating speed of bottom roller 32；As 1 thickness G T.GT.GT 1.6mm of steel band, selection control 111 connects torque by thickness G T.GT.GT 1.6mm branch roads 106
Amplitude limit control block 108, the torque amplitude limit control block 108 input kink region tension variation value 101, kink strip speed
Actual value 102 and torque feedback value 104, output bottom roller regulating command 110, the bottom are calculated by torque amplitude limit control block 108
Roller regulating command 110 by the first master winch of Frequency Converter Control kink 81, the second master winch of kink 82 and the first bottom roller of kink 31,
The rotating speed of the second bottom roller of kink 32；Its kink region tension variation value 101 is the detected value of model C CR1-10T tensometers
And the difference of setting value.
The Computing Principle of its control block is as follows：
If the tension force setting value in kink region and the deviation of actual value are Δ T.
（1）As thickness≤1.6mm of strip 1, the speed of master winch and bottom roller is calculated.
If Ve is the speed of service of kink strip steel at entry 1, Vd is that kink exports the speed of service of strip 1, due to the work of kink
With being linking process section and entrance, production line is kept continuously to run during welding or when production is abnormal, then the entering of kink,
Muzzle velocity deviation：
∆V=Vd-Ve
Slewing rollers among two loop trolleys（22）Speed be：
1. the translational speed of master winch is set as VDR：
VDR=1/14 ∆V
It is so available, master winch speed regulating command（109）=f (1/14 V, T), wherein f (x) are that tension force is inclined
The functional relation converted between difference and speed deviation, as V ＞ 0 kink decline, as V ＜ 0 kink rise, when V=
Kink is motionless when 0.
2. calculate the rotating speed of kink bottom roller：
If the speed setting value of bottom roller（103）For V1n, wherein n=1,2,3 ... 6；If speed actual value（102）For VACTIf
Velocity deviation is α, then the regulating command (110) exported=f (α, T).
Wherein, No.1 loop trolley 41 has 6 foundation rollers successively from front to back along the traffic direction of strip 1,
V1n=Ve+VDR∙n=Ve+∆V/14∙n=Ve+n/14∙(Vd-Ve )
α=(V1n-VACT )
Wherein, No. two loop trolleys 42 have 6 foundation rollers, the setting of its speed successively from front to back along the traffic direction of strip 1
It is worth for V2n, wherein n=1,2,3 ... 6；
V2n=Vd-VDR∙n=Vd-∆V/14∙(7-n)=Vd-((7-n))/14∙(Vd-Ve )
α=(V2n-VACT )
（2）As the thickness G T.GT.GT 1.6mm of strip 1, the speed of master winch and bottom roller is calculated.
1. the speed of master winch is set as VDR, remain as：
VDR=1/14 ∆V
2. calculate the rotating speed of kink bottom roller：
Now select branch road（106）The torque for combining the motor itself is subjected to amplitude limit control, as shown in figure 3, when production
During more than 1.6mm think gauges, kink region motor load is big.If motor feedback torque is percentage Tn, when load is more than 50%
Amplitude limit control is performed, load is defined to 95%, upper limit control is performed when motor load occur and exceeding this limit value.
So for No.1 loop trolley 41 bottom roller output regulating command：
So for No. two loop trolleys 42 bottom roller output regulating command：
By the way that the upper limit control of kink bottom roller torque can be reduced in time the load of motor, the power of motor is turned to be added to
On master winch and slewing rollers, prevent bottom roller overload from tripping.
