In order to illustrate effect of the invention, point of power is carried out to finishing mill 1, the rolled piece 8 of Laying head 6 and place between them
Analysis, first simplifies it, as shown in Fig. 3, is further simplified as one end and fixes (rolled piece is quite fixed in milling train end), and one
End applies the suspended-cable structure of pulling force (pinch roller is indeformable to rolled piece, is equivalent to and only applies pulling force), and the present embodiment is with uniformly distributed 3
Telescoping support roller mechanism 7 supports rolled piece 8, and three telescoping support roller mechanisms 7 act on rolled piece, is 3 statically indeterminate problems,
As shown in Fig. 4, though being statically indeterminate problem, it is suspended-cable structure, can only bear supporting force, and suspension cable is also subjected to pulling force F
With 5, three finishing mill 1, pinch roller telescoping support roller mechanisms 7 totally 5 supporting forces, 5 supporting forces be respectively ql/8, ql/4,
ql/4,ql/4,ql/8.When no 3 telescoping support roller mechanisms 7 act on, the sagging intermediate maximum of suspension cable is p, 3 institute of attached drawing
Show.This sag is related with pulling force F, and relationship sees below formula between sag p and pulling force F and specific loading q:
F=qL2/(8p)
In formula: F is the pulling force in suspension cable, kg；
Q is suspension cable Unit Weight, kg/m；
P is maximum sag, m among suspension cable；
L is the length of suspension cable between two pillars, m.
P=qL as seen from the above equation2/ (8F), from the point of view of never scratching wire rod, maximum sag p is answered smaller among suspension cable
It is better, between suspension cable Unit Weight q and two pillars in the certain situation of length L of suspension cable, to maximum sagging among suspension cable
It is small to spend p, it is necessary to increase pulling force F, but the increasing of pulling force F be it is limited, be enough to be that wire rod generates plastic deformation when being increased to, just
Wire rod can be broken, bull is formed, the increasing of maximum sag p can also be such that wire rod directly contacts with sliding roller-way among suspension cable, make
Slide roller-way accelerated wear test.In the certain situation of F and L, thick specification wire rod is sagging more some more.

| 10.5 | 0.675 | 16.0 | 1.567 |
If the minimum value of F in the case where calculating below without backing roll, if L is 10m, rolling wire rod diameter is 10mm,
If sliding roller-way height is 20mm, p is up to 10mm, and corresponding F is minimum at this time are as follows:
F=qL2/ (8p)=0.612 × 102/ (8 × 0.01)=765 (kg)
The stress of wire rod cross section are as follows: 95.5MPa.If the resistance of deformation of wire rod at this time is only but in 700-1000 DEG C of finish to gauge
There is 50-80MPa or so, so completely hanging in this 10m to rolled piece, it is impossible for not contacting with sliding roller-way, otherwise
If will be pulled off.
The minimum value of the F in the case where increasing by 3 telescoping support roller mechanisms 7 is seen below, and L=10/4mm, p still take at this time
0.01m, corresponding F is minimum at this time are as follows:
F=qL2/ (8p)=0.612 × 2.52/ (8 × 0.01)=47.81 (kg)
The stress of wire rod cross section are as follows: 5.97MPa.In 700-1000 DEG C of finish to gauge, the resistance of deformation of wire rod at this time is 50-
80MPa or so, 5.97MPa ratio 50MPa are much smaller, thus rolled piece do not contacted with sliding roller-way be completely can be with.In order to more protect
Stress in wire rod cross section, is increased to 10MPa by danger, and corresponding pulling force F increases to 80.1kg at this time, and corresponding p is 6mm.
Find out that every 2.5m long sliding roller-way increases by 1 backing roll from being analyzed above, so that it may connect rolled piece with sliding roller-way in rolling
Touching, and the tension in rolled piece is made to be significantly smaller than wire rod resistance of deformation, it is substantially eliminated so that rolled piece be made to scratch with bull.
