The theoretical foundation of the inhibition Mill chattering of bounce by reducing rolled plate of the invention is:
In the high-speed rolling of rolled plate, the bounce of rolled plate causes the fluctuation of the rolling entrance velocity of rolled plate,
The length of inlet of rolling mill side rolled plate is caused to change, i.e. entrance side rolled plate length variable quantity:
Wherein Δ μ1For the undulate quantity for rolling entrance velocity；
Entrance side rolled plate length variation delta L causes the fluctuation of rolled plate entrance tension, i.e. rolled plate entrance
The variable quantity of tension:
Wherein, E1For elasticity modulus；
According to classical tube rolling simulation model, the fluctuation of rolled plate entrance tension directly results in the fluctuation of roll-force, i.e.,
The undulate quantity of roll-force caused by rolled plate entrance tension variation amount Δ L:
Wherein, QPIt indicates stress status modulus, is calculated by Hill formula；B indicates rolled plate width；Δ h is indicated
Absolute draft amount；R ' expression roll flattening radius, is determined by Hitchcock formula, it may be assumed thatIn formula:
R- working roll radius, P- roll-force, C0- Hitchcock constant,E1For elasticity modulus, γ is working roll pool
Loose ratio.
The fluctuation of roll-force directly causes the flutter of milling train and the fluctuation of rolled plate exit thickness；
On the one hand the flutter for rolling fast mill caused by fluctuation directly results in the fluctuation of rolling entrance velocity；It is another
Aspect, the flutter of fast mill can cause indirectly the wave of rolled plate exit thickness by influencing operation roll of mill vibration displacement
It is dynamic, and the fluctuation of rolled plate exit thickness directly results in the fluctuation of rolled plate entrance velocity.
Its relationship is as follows: the flutter of fast mill makes two working rolls of milling train generate vibration displacement Y, and working roll vibrates position
It moves: Y=Ymcosωt
The variation of working roll vibration displacement causes the variation of rolled plate exit thickness y2, i.e. rolled plate exit thickness:
y2=y2m+ 2Y=y2m+2Ymcosωt
In above formula, y2mAverage value is represented, it is equal by moment metal mass flow any in rolling roll gap, then there is formula: μ1y1
=μ2y2=Φ
Wherein, Φ is the metal flow of moment in roll gap；Preceding sliding rate is constant, i.e. μ2It remains unchanged.
From the above equation, we can see that rolled plate exit thickness y2Variation cause rolled plate entrance velocity μ again1Fluctuation, i.e.,
Rolled plate entrance velocity:
Wherein, the speed that unreels of unreeling machine keeps constant μ1mIt remains unchanged.
Above formula shows that the entrance velocity of rolled plate increases Δ μ1。
Beneficial effects of the present invention: it is used in the left side of milling train the present invention, and rolled plate rolls inlet and rack is arranged,
Overdraught support roller and downstream support roller are mounted on the rack, overdraught support roller be arranged in downstream support roller just on
Side, the distance between overdraught support roller and downstream support roller H are 2-5 times of rolled plate thickness h, i.e. H=(2-5) h rolls
The technical solution between overdraught support roller and downstream support roller is arranged in panel, utilizes overdraught support roller and downstream
The high pressure draught that airflow hole in support roller ejects realizes the support to rolled plate, meanwhile, pass through overdraught control valve
Door realizes the control of the high pressure draught ejected to airflow hole with upper air gauge and downstream control valve and lower air gauge
System, therefore, can realize the support of rolled plate in the way of non-contacting, reach and reduce the mesh that rolled plate moves up and down,

In the high-speed rolling of rolled plate, the bounce of rolled plate causes the fluctuation of the rolling entrance velocity of rolled plate,
The length of inlet of rolling mill side rolled plate is caused to change, i.e. entrance side rolled plate length variable quantity:Its
Middle Δ μ1For the undulate quantity for rolling entrance velocity；
Entrance side rolled plate length variation delta L causes the fluctuation of rolled plate entrance tension, i.e. rolled plate entrance
The variable quantity of tension:Wherein, E1For elasticity modulus；
According to classical tube rolling simulation model, the fluctuation of rolled plate entrance tension directly results in the fluctuation of roll-force, i.e.,

Fast mill flutter, on the one hand directly result in rolling entrance velocity fluctuation；On the other hand, the flutter of fast mill can lead to
Crossing influences the fluctuation that operation roll of mill vibration displacement causes rolled plate exit thickness indirectly, and rolled plate exit thickness
Fluctuation directly results in the fluctuation of rolled plate entrance velocity again.
Its relationship is as follows: the flutter of fast mill makes two working rolls of milling train generate vibration displacement Y, and working roll vibrates position
It moves: Y=Ymcosωt
The variation of working roll vibration displacement causes rolled plate exit thickness y2Variation, i.e. rolled plate exit thickness: y2
