Description
Technical field
The present invention relates to metal freezing and continuously casting field, in particular to a kind of two roller continuous casting billets with inclination roll
Roll angle apparatus.
Background technique
In Modern World plate & strip production technology, side is directly split or upwarping defect is generally existing, especially in the recent period in
The broadening ratio of the development of Heavy plate production technology, plate constantly increases, and sheet material edge is directly split or upwarping defect is also further from plate
Edge, and it is further close to center.Iron and steel enterprise, which has to use, to increase cutting edge amount, reduces the mode of lumber recovery to cut off
Drawbacks described above meets the requirement of quality.This results in being significantly increased for enterprise's production cost.
For this purpose, metallargist is in addition to being taken other than optimizing in terms of steel quality, two refrigeration techniques, rationally rolling
A technical measures be exactly using the crystallizer technology with chamfering.In the prior art, the knot using side with chamfering
Brilliant device technology is commonplace.It can be with effective solution slab transverse corner crack line although with the crystallizer technology with chamfering
Problem, still, mass production practice result show: the continuous casting billet produced using the chamfer crystallizer technology of above-mentioned parameter,
Due to its fillet surface and wide face is formed above and below slab chamfer angle is smaller, generally less than 135 °, the slab of the shape with
The defects of edge of Strip is directly split or sticks up skin can not be completely eliminated in the operation of rolling afterwards.
Therefore, some metallargists develop the method rolled to the corner of slab both at home and abroad, to obtain corner
The more reasonable continuous casting billet of shape.
Such as Chinese patent CN204747439U discloses " a kind of device for carrying out the rolling of continuous casting billet corner ", which puts
It sets in the left and right sides of slab, i.e., the chamfering roll for thering are a upper and lower ends to have convex edge in every side of slab, drive
Driving under, the chamfering roll with convex edge is rolled to slab, and is rolled using corner of the convex edge of roll to slab, realize
To the chamfering in slab corner, corner shape is advanced optimized, is directly split to meet elimination edge in the cut deal broadening operation of rolling
Or the demand for the defects of sticking up skin.But in production application, the chamfering roll with convex edge is the side from side to squeeze
Formula is rolled to slab corner, rather than forward direction rolls the corner of slab.This just inevitably brings two problems: first is that
Draught pressure is big, second is that due to friction so that roll campaign reduces.
Summary of the invention
For above-mentioned defect existing in the prior art and deficiency, the object of the present invention is to provide one kind to have inclination roll
Two roller continuous casting billets roll angle apparatus.
To achieve the goals above, the present invention provides the following technical scheme that
The present invention provide it is a kind of with inclination roll two roller continuous casting billets roll angle apparatus, which includes chamfering roll 1, rolls
Roller braced frame 3, connector 4 and driving push rod 5；
The roll stand frame 3 is connect with the driving push rod 5 that can be moved forward and backward, two cantilevers of roll stand frame 3
End is respectively arranged with a chamfering roll 1；
Two chamfering rolls 1 are oppositely arranged, and the roll surface of chamfering roll 1 and the wide face of slab are at inclination angle；The device is mounted on
6 left and right sides of continuous casting billet, continuously rolls the corner of continuous casting billet 6.
Two chamfering rolls 1 on two cantilever ends of the roll stand frame 3 are symmetrical arranged or asymmetry is set
It sets.
Two cantilever ends of the roll stand frame 3 are " U "-shaped or " Y " structure, and frame mid portion is by driving push rod 5 through even
Fitting 4 drives.
The wide face setting at α angle of the roll shaft 2 and continuous casting billet 6 of the chamfering roll 1, α angle are 0 °~45 °；Chamfering roll 1
Roll surface and the wide face of continuous casting billet 6 or the wide face contact point of the arc roll surface and continuous casting billet 6 of chamfering roll 1 curved cut line and company
The wide at angle β setting in face of slab 6, β angle are 1 °~45 °.
The chamfering roll 1 and roll shaft 2 are separate structure, or are structure as a whole.
The roll surface of the chamfering roll 1 is uniform cylinder, is perhaps uniform frustum shape or be arc
Frustum, or be shape with groove.
The diameter of the chamfering roll 1 is 100~350mm, and the roll surface length of chamfering roll 1 is 100~350mm.
The driving force for pushing driving push rod 5 to move is hydraulic coupling, electric power or mechanical force.
The exit of conticaster is arranged in the device, or is arranged in continuous casting machine fan-shaped intersegmental part.
Corner of the device for square billet, rectangular bloom or slab rolls, and applicable thickness of strand is 90mm~500mm.
The device had both been suitable for the rolling of chamfering continuous casting billet, was also suitable for the rolling of right angle slab and arc chord angle continuous casting billet.
Compared with prior art, the beneficial effects of the present invention are:
Apparatus of the present invention are mounted at left and right sides of continuous casting billet, with the progress of conticaster process of billet withdrawal, have inclination roll
Two roller continuous casting billets to roll the driving push rod 5 of angle apparatus mobile towards continuous casting billet under the driving of power, and to the corner of continuous casting billet 6
It is rolled.Then, as the movement of slab, chamfering roll 1 continuously carry out rolling rolling to the corner of continuous casting billet 6, chamfering is rolled
Roller 1 mainly determined the amount of rolling in 6 corner of continuous casting billet by the driving force of driving push rod 5, the bigger continuous casting billet corner of driving force
Chamfer amount is bigger.Simultaneously as the axis of chamfering roll 1 is inclined, the roll surface inclination of cooperation chamfering roll 1, so that it may obtain
The preferable angle of positive rolling is carried out to continuous casting billet corner, and required slab corner is obtained under conditions of smaller roll-force
Shape.Simultaneously as reducing the friction between roll and continuous casting billet, roll campaign is greatly improved.
The forward direction rolling to continuous casting billet corner may be implemented in the present invention, therefore resistance is small, plant maintenance is simple with rolling
The advantages that.
