Description
Technical field
The invention belongs to metal rolled technical fields, are related to a kind of heat in coupled pickling and tandem mill or continuous acid-washing unit
Roll the accessory device on the straightening descaling mill before strip pickling, specifically a kind of adaptive working roll box of straightening descaling mill.
Background technology
In coupled pickling and tandem mill or continuous acid-washing unit, in order to improve the pickling efficiency of hot-strip, lead to before pickling
Often scale breading is carried out to Surfaces of Hot Rolled Strip, and straightening descaling mill is the key equipment for abolishing belt steel surface iron scale.Due to
The iron scale of belt steel surface is fragile material, and base material is elastic-plastic material, when strip is by straightening descaling mill, is broken with straightening
The strip of squama machine working roll contact side is by compressive deformation so that the iron scale on its surface crushes, and opposite side is drawn
Stretch deformation so that the iron scale on its surface cracks.Hot-strip is by the stretch bending repeatedly on each working roll so that
The iron scale on its surface is loose and partial exfoliation.Straightening descaling mill is generally two curved one strong structure types, i.e. two groups of bendings
Unit and one group of resistance straightening unit.Every group of bending unit includes 2 sets of bending working roll boxes, i.e., is bent working roll roller box each one above and below
Set, the working roll box of resistance straightening unit only have a set of, the either working roll box of the working roll box of bending unit or resistance straightening unit,
Collectively termed as working roll box.
In production, hot-strip during straightening descaling mill with working roll by can contact, since working roll is driven voller,
Therebetween friction can be generated, work roll surface is caused to wear.If preferable in incoming profile, work roll surface can be equal
Even abrasion, but in most cases, hot rolling raw material plate shape is all undesirable, there are various shape waves, in addition existing straightening is broken
Squama machine working roll roller box itself rigidity it is all relatively good, when leading to strip by straightening descaling mill working roll, work roll surface by
Strip pressure be usually unevenly distributed, in this way working roll work a period of time after, by two close end local roll surface wearing compared with
To be serious, i.e., eel-like figure shape region is all formed at the both ends of working roll, small both ends are big among this shape, and the presence of camber
It can aggravate the abrasion of working roll.When the strip of production narrows from the width, this working roll being seriously worn still uses, once
The strip that width specifications are more than the uniform roll surface length of working roll is produced, during due to strip by eel-like figure shape region on working roll,
The iron scale of the region belt steel surface cannot be abolished effectively, the work that just must more renew at this time due to deforming uneven
Make roller, otherwise can seriously affect the subsequent pickling effect of hot-strip and rolling quality, and then influence end product quality.Cause
And existing roller box structure type can cause the working roll service life not grown, roll change frequency increases, and affects unit to a certain extent
Normal operation, increase production run cost.
Therefore, it is highly desirable to explore a kind of working roll box structure of completely new straightening descaling mill so that working roll has
The ability of certain stress for adapting to supplied materials template, adjust automatically and Surfaces of Hot Rolled Strip, makes work roll surface uniformly grind as far as possible
Damage so as to improve the working roll service life, reduces roll change frequency, and then reduce the production run cost of unit.
Invention content
In view of this, the purpose of the present invention is to provide a kind of adaptive working roll boxes of completely new straightening descaling mill, should be certainly
It adapts to working roll box and passes through the adaptive flexible deformation of flexible deformation mechanism at work so that there is working roll automatic adaptation to come
The ability of the stress of flitch type, adjust automatically and Surfaces of Hot Rolled Strip makes work roll surface uniform wear as far as possible, so as to
The working roll service life is improved, reduces roll change frequency, and then reduce the production run cost of unit.
In order to achieve the above objectives, the present invention is achieved through the following technical solutions：
The present invention provides a kind of adaptive working roll box of straightening descaling mill, including roller box body, is set on the roller box body
It is equipped with working roll, the Support roller assembly for being used to support working roll, leap-preventing device and use for preventing working roll axial direction roll shifting
In the roll wheel assembly that roller box body slides, the roller box body includes pedestal I and is located by connecting on pedestal I by connector
Pedestal II is provided with flexible deformation mechanism between the pedestal I and pedestal II.
When further, the quantity of the flexible deformation mechanism, permutation and combination method are by the length of working roll and its work
Stressing conditions determine that quantity can be single or multiple, and permutation and combination method can be single multigroup or multiple rows of multigroup symmetrical
Arrangement.
Further, the pedestal I is provided with the section vertical with its length direction and takes the shape of the letter U the groove of structure, the pedestal
II is provided with the boss with groove snap fit；The connector is bolt.
Further, flat key is provided between the pedestal I and pedestal II and on the center line along I length direction of pedestal,
The stressing conditions when shape of the flat key, size, quantity are by the length of working roll and its work determine.
Further, being provided between the pedestal I and pedestal II allows the gap H of flexible deformation deformation, between described
The height of gap H is determined by the length of working roll with stressing conditions during its work.
Further, the flexible deformation mechanism is made of the axis pin of elastomer and the one or more elastomers of series connection.
Further, the elastomer is disc spring or spring or polymer rubber alloy elastic body or metal-rubber elastomer.
The advantage of the invention is that：
1) adaptivity
