Description
Technical field
The present invention relates to a kind of magnesium alloy thin plate and band Coupling Deformation combination rolling system and its milling method, it belongs to a kind of
Rolling magnesium alloy sheet equipment and its milling method.
Background technology
The traditional Rolling Production mode of magnesium alloy board is generally that multi-pass tandem rolling or single chassis are back and forth rolled, and back and forth rolls energy
Enough greatly improve production efficiency.But full axial rolling causes and rolls rear magnesium plate band and show strong Anisotropy, causes follow-up
Deep processing be difficult to；Existing scholar's research goes out equal channel angular rolling method, and the method is that one kind can realize continuous confined strip shearing
Milling method, can making the crystal grain of magnesium alloy plate, to be orientated by basal plane orientation transition be non-basal plane orientation, and then is magnesium alloy
More slip systems are provided, its plastic deformation ability can be substantially improved.Have through the magnesium plate Anisotropy after equal channel angular rolling
It is significantly improved, it is fast yet with magnesium alloy heat radiation, all need to melt down to reheat after the completion of every time rolling.Simultaneously because isometrical
The special process at angle, it is impossible to realize tandem rolling or reversible reciprocal rolling, the production efficiency of equal channel angular rolling is thus constrained significantly.Separately
Outward, the sliding-frictional resistance during magnesium plate detrusion by mould can cause the defect of Instability wrinkling and crackle, magnesium plate to be received
To mould bend in one direction, cause the residual stress distribution for rolling rear magnesium plate uneven, it is easy to the defects such as plate shape wave occur.
The content of the invention
Present invention aim to address traditional rolling mill practice exist roll rear magnesium alloy thin plate and band Anisotropy it is strong,
The low technical problem of defect is serious, lumber recovery is low and equal channel angular rolling method is present production efficiency is split on plate shape and side, there is provided
A kind of magnesium alloy thin plate and band Coupling Deformation combines rolling system and its milling method.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of magnesium alloy thin plate and band Coupling Deformation combines rolling system, and it is sheared by two uncoiling-coiling machines, two five rollers
Bending large deformation adjustable apparatus, two three-roll unbenders, two pinch roll apparatus and six roll reversing rollers composition, First are opened
Volume-coiling machine, the roller shear-bow large deformation adjustable apparatus of First five, First three-roll unbender and First pinch roll dress
The front for being sequentially arranged six roll reversing rollers is put, second pinch roll apparatus, second three-roll unbender, second five roller are cut
Cut bending large deformation adjustable apparatus and second uncoiling-coiling machine is sequentially arranged the back of six roll reversing rollers, realize past
Magnesium alloy thin plate and band is rolled again；The five rollers shear-bow large deformation adjustable apparatus are by two rollers predeformation list moving up and down
Unit and the fixed roller redeformation unit of turriform three composition, are deformed by the regulation shear-bow that moves up and down of two roller predeformation units
Angle, θ, make five roller shear-bow large deformation adjustable apparatus to sheet material apply rolling predeformation and redeformation；The model of angle, θ
Enclose is 90~120 °.
Two uncoiling-coiling machines, two five roller shear-bow large deformation adjustable apparatus, two three-roll unbenders,
Two pinch roll apparatus and six roll reversing rollers are mounted on temperature heating and temperature-detecting device.
A kind of milling method that rolling system is combined using above-mentioned magnesium alloy thin plate and band Coupling Deformation, it passes through first first
Magnesium alloy strip coil after platform uncoiling-coiling machine will be preheated through bell type heating furnace is opened, and the magnesium alloy strip coil after uncoiling passes through first
The roller shear-bow large deformation adjustable apparatus of platform five apply the predeformation before rolling, the magnesium alloy of predeformation to sheet metal thickness direction
Band is involved in be aligned into First three-roll unbender, and the magnesium alloy strip coil after aligning enters six via First pinch roll apparatus
Roll reversing roller is rolled, and the magnesium alloy strip after rolling sends into second three-roll unbender via second pinch roll apparatus
Aligning again before being crimped, becoming again after being rolled into second five roller shear-bow large deformation adjustable apparatus afterwards
Shape, finally enters second uncoiling-coiling machine and is batched, when First uncoiling-coiling machine tape coil diameter detection device detect it is surplus
During remaining last 2 circle, all fronts equipment stops, and starts antiport, the reverse rolling of magnesium alloy strip coil is carried out, until being finally completed into
Product rolling is shut down.
Because present invention employs above-mentioned technical proposal, solve existing rolling mill practice presence rolls rear magnesium alloy thin plate and band
It is low that Anisotropy is strong, the production efficiency that defect is serious, lumber recovery is low and equal channel angular rolling method is present is split on plate shape and side
Technical problem.Therefore, compared with background technology, the present invention has the advantage that and improves is：
1) five roller shear-bow large deformation adjustable apparatus of arrangement apply rolling predeformation and again to sheet material before and after milling train
Deformation.The Coupling Deformation mode can effectively induce sheet material that detrusion occurs and stretch twin and dynamic recrystallization forming core, favorably
In the tissue and texture structure of regulation and control magnesium alloy, reach reduction basal plane texture, crystal grain thinning, reduce anisotropy and plate shape ripple
Wave, and crack defect.
2) detrusion is applied by the roller redeformation unit rotational of turriform three (being rolling friction between plate roller), is effectively overcome
Because being sliding friction between plate roller at the sheet processed by equal deforming moulds of footpath, thin plate rolling is caused the defect of unstability, corrugation and crackle occur.
3) the roller redeformation unit of turriform three employ multiple roll combination turriform roll structure, solve its rigidity, low intensity without
The structure problem that method is supported using bearing.
4) five roller shear-bow large deformation adjustable apparatus effectively overcome current magnesium alloy plate asymmetrical rolling because of roller speed
There is plate face micro-crack defect, crystal grain refinement, texture type transformation and basal plane texture attenuation deficiency etc. and ask than matching improper
Topic.
5) present invention is provided simultaneously with the high efficiency of reversible reciprocal rolling and the improvement magnesium plate of equal channel angular rolling respectively to different
The advantage of property and overcome two kinds of deficiencies of technique.Reversible reciprocal rolling and the unification of equal channel angular rolling are realized, is carried significantly
It is high to roll rear magnesium plate performance and production efficiency.
