It can change strip steel tensile stress cross direction profiles, is adapted to that strip steel is reversible to be rolled and continuous rolling production line.
Background technology
During carrying out cold-rolled strip steel shape setting and Strip Shape Control, rolling tensile force has heavy to closing to belt plate shape
The effect wanted.Increase rolling tensile force by reasonable, the horizontal mobility of metal can be increased, so that exit thickness is reduced, rolled piece section is more
Plus uniformly, obtain good surface quality of strips.Meanwhile, increase rolling tensile force can reduce the draught pressure in the operation of rolling and roll
Load processed, reduces the resistance of deformation of band, reduces the abrasion of roll, prevents strip running deviation it is ensured that the operation of rolling is more steady.Though
So increasing rolling tensile force has many advantages, such as above, but tension force sets nor excessive, and overtension can lead to metal that plasticity occurs
Deformation, makes steel edge portion crackle, or even strip steel is broken, cause broken belt accident.From the foregoing, the control of rolling tensile force
Rolling is smoothed out particularly significant with profile regulation, if the distribution of the horizontal tensile stress of band can be changed, can be to band

In the Tokyo iron and steel rolling meeting of 1980, propose to use by Italian Borghesi (M. Bao Fuxi) and Choizz
The method changing entrance tension distribution controls plate shape, and actually this idea is to be applied to strip steel by several short rollers that can individually lift
Plus necessary pressure, thus changing the tensile stress distribution of band, this is known as tensile stress and controls roller-TDC roller.Gone out by milling train
Flatness detection device at mouthful, the tensile stress of detection cross direction profiles, control the lifting of TDC roller according to testing result, change entrance
Tensile stress is distributed, till plate shape is qualified.Although Borghesi et al. proposes this method improving plate shape, do not carry
Go out specific embodiment, and in this kind of method when short roller applies pressure to strip steel, the local strip steel stress of short roller both sides
Concentrate, elastic deformation occurs, when pressure is excessive, can cause local strip steel that plastic deformation occurs, destroy strip surface quality, no
Beneficial to belt steel rolling.If the stress concentration of strip steel local can be improved, the method is a kind of effective Strip Shape Control means.
The Gang Hukeheyoucun of NKK thoroughly et al. the serious analysis spreading range of uneven tensile stress distribution and front,
Effect in Strip Shape Control for the tensile stress it is proposed that control the imagination of plate shape with changing toe-out stress distribution afterwards.According to mechanics
In St.Venant (Saint-Venant) principle, with the increase with point of force application distance, be applied to uneven point on strip steel
The tensile stress of cloth can gradually tend to being uniformly distributed.They experiments prove that tensile stress uneven distribution controls the feasible of plate shape
Property, TDC test is done thereafter on experimental mill, has been arranged in the height of strip steel two side portion short roller particular by regulation and inclines
Gradient, to apply different power to steel edge portion, thus producing different tensile stress distributions.But this device is only in strip side portion area
Domain applies tension force, is effective for wave in eliminating, but is difficult to control to for other flatness defects, and complex structure, no
Can be corresponding with flatness detection system, its application is greatly limited.
Domestic Zhang Ming proposed tension stress distribution control roller (CN200810114678.7) in 2008, particular by sky
The setting internal diameter bearing group bigger than hollow axle external diameter on heart axle, be designed between bearing group each bearing inner race and axle cylinder (or
Pressure cylinder), extending and retracting by cylinder piston rod, control the position that bearing is with respect to hollow axle, such bearing outer ring can
So that different pressures are applied to strip steel, form uneven tensile stress distribution.It should be pointed out that there is one fixed width the outer ring of bearing, when
When bearing applies pressure to strip steel, stress raisers in bearing both sides strip steel, unfavorable to strip surface quality；In addition, axle
Hold and fixing axially through round nut, mention bearing inner race plus tolerance, outer ring negative common difference in literary composition, bearing inner race had both needed axial pressure
Tightly, need to move radially, enforcement difficulty is larger, and bearing is under the circumference of the high-speed rotation, has thermal expansion, such bearing again
That axially can block is tighter, is unfavorable for moving radially；Meanwhile, hollow axle internal structure is complicated, and each cylinder has been required for gas source pipe
Road, with each cylinder interface attended operation narrow space it is difficult to operation, leading to this device to be difficult in actual production should for pipeline
With.
