Description
Technical field
The present invention relates to the methods that tail part of band steel scroll quality is improved in hot rolling technology.
Background technology
Coiling machine is the important equipment of hot rolling line, for hot-strip to be rolled into coil of strip.Coiling machine is located at finishing mill
It is last procedure of hot continuous rolling production line after group.Referring to Fig. 1 and 2, strip 1 is delivered to from mm finishing mill unit by roller-way 3 and batched
Machine unit enters pinch roller 51 using the centering of flipper guide 41.The main function of pinch roller is that the steel stage is stung on head to band
Steel applies certain clamping force, while implements first time flexural deformation to it；Stabilization is applied to strip in afterbody coil ing one
Tension, to ensure good scroll quality.Three helps of Wrapping Roll 6 bend strip, and strip is made tightly to wind coiling 7.Volume
After cylinder 7 is in strip winding, tension is applied to it, to ensure that scroll is up-to-standard.
To ensure that serialization uninterruptedly produces, 2 to 3 coiling machines usually can be sequentially equipped on a hot rolling line
(such as what is shown in Fig. 1,2 is configured with 3 coiling machines), so when a coiling machine carries out unloading the operation of coil of strip, other
Coiling machine can work normally, so as to ensure continuous production.As shown in Figure 1, 2, it is also each on two coiling machines below to be equipped with
There are a pair of of flipper guide 42,43 and a pair of of pinch roller 52,53.
After strip is rolled into coil of strip, it may appear that some defects, such as overflow edge defect, flanging defect, side damage defect etc..
For example, referred to as overflow edge defect when the outer volume layer of coil of strip part protruding upward or downwardly projecting is more than certain standard；In the presence of excessive
In transportational process, edge easily causes to bend the coil of strip of side defect by the damage of driving fixture, is referred to as flanging defect；Strip edge
Portion because flipper guide scrape or transportational process in occur breakage caused by the defects of referred to as side damage defect.Overflow edge, flanging and side damage
Defect can seriously affect user's use, and may cause broken belt accident when cold rolling continues production.So drawbacks described above is user
Unacceptable defect, it is necessary to defect part be cut off in finishing procedure, so will also result in quality cost loss.
Coiling process of the prior art is described with reference to figure 3 to 5.As shown in figure 3, to batch chain-drive section speed control rank
Section：In 11 crossing process of head of strip 1, roller-way 3, pinch roller 5, reel 7 are using speed control, and speed is slightly larger than strip
The speed of service.As shown in figure 4, it is the tension force stage in the middle part of coiling machine：When the head of strip 1 enters coiling machine winding coiling
7 and after torque rises to setting moment values, the basic automatization computer of coiling machine just determines that reel tension is successfully established,
It entirely establishes hypertension to terminate, subsequent reel is switched to Torque Control state, and coiling machine enters the middle part tension force stage.This
When, tension is provided by batching the reel 7 of unit and the last rack 21 of mm finishing mill unit, and pinch roller 5 hardly provides tension.Such as figure
It is afterbody coil ing one shown in 5：After the afterbody 12 of strip 1 is dished out by the last rack 21 of mm finishing mill unit, reel 7 switches immediately
For speed control, pinch roller 51 is Torque Control, and tension is provided jointly by reel 7 and pinch roller 5 at this time, until entire volume steel coil
Take end.
Fig. 7 and Fig. 9 is respectively from the coiling process schematic diagram overlooked shown in visual angle.In 52 coiling band steel 1 of the second coiling machine
When, as shown in fig. 7, when the head of strip 1 reaches the pinch roll inlet of the second coiling machine 52, a pair of second flipper guide 42 closes up
(being respectively arranged at the second flipper guide of a pair 42 of 3 both sides of roller-way towards the center line movement of roller-way 3) is to clamp strip 1.
The second flipper guide of a pair 42 closed up is so that enter the position centering of the strip 1 of the second coiling machine 52, so as to ensure that coil of strip
Scroll quality.Hereafter, after the afterbody of strip 1 enters the second coiling machine 52, in order to ensure the normal operation of follow-up strip, one
Second flipper guide 42 is opened and (is respectively arranged at the second flipper guide of a pair 42 of 3 both sides of roller-way away from roller-way 3
The direction movement of heart line), to be returned to initial position.
In the 3rd 53 coiling band steel 1 of coiling machine, as shown in figure 9, when the head of strip 1 reaches the folder of the 3rd coiling machine 53
When sending roller entrance, a pair of 3rd flipper guide 43 close up (be respectively arranged at the 3rd flipper guides 43 of a pair of 3 both sides of roller-way towards
The center line movement of roller-way 3) to clamp strip 1.The 3rd flipper guide 43 of a pair closed up is so that enter the band of the 3rd coiling machine 53
The position centering of steel 1, so as to ensure that the scroll quality of coil of strip.Hereafter, when strip 1 afterbody into the 3rd coiling machine 53 it

3rd flipper guide 43 is moved away from the direction of the center line of roller-way 3), to be returned to initial position.
The shortcomings that can will become apparent from the prior art referring to Fig. 6.In afterbody coil ing one, the afterbody of strip 1 is by finish rolling
After unit end rack 21 is dished out, the strip of pinch roller 5 to magnetic tape trailer part loses tension, in relaxation, unstable state.Relaxation
Strip coiling when, easily generate overflow edge, flanging and side damage defect.
The prior art solves the problems, such as this using the method for roller-way hysteresis：When the afterbody of strip is thrown by mm finishing mill unit end rack 21
After going out, the speed for reducing roller-way 3 makes it below the speed of service of strip.Band is tightened by the frictional force of roller-way and strip lower surface
Steel improves the stability that tail part of band steel is run on roller-way.
But the above method still has following deficiency：
1) when Thin Strip Steel (such as thickness is less than or equal to the strip of 4mm) batches, effect is poor：Using the speed for reducing roller-way
The speed of service of strip is made it below, effect is preferable when Deformation in thick batches, but Thin Strip Steel is from heavy and light, strip following table and roller-way
Frictional force is small, and tail part of band steel cannot be tauted, and still in relaxation, unstable state, mass defect can not avoid.
2) quality of strip lower surface is influenced：Roller table speed is less than strip speed, can not be kept away between strip following table and roll surface
Exempt from the presence of friction, influence surface quality.In order to tighten Thin Strip Steel, it is necessary to increase the speed difference between roller-way and strip, but so
One, cause the possibility of surface defect also to increase.
