Description
Technical field
The invention belongs to steel rolling auxiliary equipment technical field, relate in particular to a kind of auxiliary equipment of assisting milling train work to be used for supporting rolled piece.
Background technology
In common rolling process, the roughing blank is after No. 1 frame is come out, blank does not stop cooling in the operation of rolling since from the blank latter end near this segment distance of roll section blank, variations in temperature difference, simultaneously since the blank off-square influence through rolling back internal stress, institute's rolling stock is no longer smooth after cooling, and easily produces torsion phenomenon, causes blank can not normally enter into down milling train one, it is useless that this not only causes the centre to be rolled, and also increased working strength of workers.Eliminate the problem of reversing and leading and adopt conventional outlet guide to solve simultaneously, because after blank is rolling, bi-directional is carried out in being delivered on the compacting blank that himself internal stress and cooling are shunk, cause that blank sends out distortion and distortion on multi-direction, conventional slip outlet guide can't be eliminated the torsional deformation of rolling blank on multi-direction, and the slight distortion that has taken place can't flatten.So need design one servicing unit, can prevent blank distortion, distortion after rolling, in order to assist the skin pass rolling blank, can increase the stability of steel bar again, avoid the generation of roughing heap steel, this device has substituted original outlet guide simultaneously, makes to change groove, roll change at ordinary times and become convenient, helps realizing grooveless rolling.
Summary of the invention
The object of the invention is to provide a kind of steel rolling roller (guide) apron, adds to be located at No. 1 milling train back of steel rolling production-line, can solve blank and come out to produce the phenomenon of distortion from No. 1 milling train, thereby effectively increase the stability of steel bar, reduces the possibility that roughing heap steel takes place.Simultaneously, because the setting up of deflector roll, make the roll change of No. 1 milling train change groove and seem easily, and be convenient to implement grooveless rolling, greatly reduce rolling fault.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of steel rolling roller (guide) apron, comprise a fixed support and two deflector rolls, it is characterized in that two deflector rolls are set up on the fixed support up and down respectively, leave the gap between last deflector roll and the lower guide roll, and at two deflector roll two ends one compression spring is set all and connects two deflector rolls up and down, at the deflector roll opposite side of compression spring correspondence, be provided with and regulate bolt and support lower guide roll and press deflector roll down, the adjusting bolt is located on the fixed support.
Described adjusting bolt is 4, and two regulate bolt supports lower guide roll, presses deflector roll under the two adjusting bolts in addition.
Described two deflector rolls are made of guide roller axis and deflector roll cover, and deflector roll is sheathed on the guide roller axis.
Described fixed support is the rectangle framework.
Described two deflector rolls are cylindrical structural, and two deflector roll diameters are 330～350mm, and distance is 105～115mm between two deflector rolls.
Correspondence is offered two hole slots on the fixed support, and upper and lower two deflector rolls are set up in the fixed support institute opening slot.
This steel rolling is installed on No. 1 milling train back in the steel rolling production-line with roller (guide) apron, and the roughing blank directly enters the set steel rolling in back with two deflector roll gap locations of roller (guide) apron restriction torsional deformation with flatten processing behind No. 1 mill milling.Lower guide roll is not only played a supporting role to rolled piece, can also limit the steel rolling of torsional deformation jointly with last deflector roll or carry out necessary leveling.Because the rolled billet through two deflector roll gaps is not what fix, need carry out real-time adjustment to the spacing of two deflector rolls.If the excesssive gap of two deflector rolls then can't play the effect of correcting and flattening, if the gap of two deflector rolls is narrow, then the frictional force between rolled billet and last lower guide roll is very big, can't realize the normal derivation of rolled billet.This steel rolling adopts upper and lower adjusting bolt to limit maximal clearance between upper and lower deflector roll with roller (guide) apron, makes the maximum torsional deformation degree of rolled billet still can satisfy the needs of back one operation processing.The compression spring is used for increasing the chucking power that goes up between lower guide roll, makes upper and lower deflector roll when the thickness of rolled billet changes, and can both play good leveling and restrained deformation effect.Bolt can precession and back-out up and down, the maximal clearance between last lower guide roll is regulated, to adapt to the limit shape and the leveling of various different size rolled billet.
Beneficial effect of the present invention is, this steel rolling can effectively solve rolled billet and produces the phenomenon of reversing from No. 1 milling train back of coming out by the flexible self-regulated deflector roll gap that is in harmonious proportion with the deflector roll rack device, thereby can effectively increase the stability of rolled billet, reduce the generation of roughing heap steel.This apparatus structure is simple, installs easy to adjustly, can limit shape and leveling processing to the rolled billet of different size thickness and distortion, and the degree of wear between its deflector roll and rolled billet is lower, long service life.
