Description
Technical field
The present invention relates to metal freezing and continuous casting field, particularly to a kind of two roller continuous casting billets tilt with roll
Roll angle apparatus.
Background technology
In Modern World plate & strip production technology, limit is directly split or is stuck up skin defect and generally exists, especially in the recent period along with in
The development of Heavy plate production technology, the broadening ratio of sheet material constantly increases, sheet material edge directly split or stick up skin defect also further from sheet material
Edge, and further near center.Iron and steel enterprise has to use increase cutting edge amount, reduce the mode of lumber recovery with excision
Drawbacks described above, meets the requirement of quality.This results in being significantly increased of enterprise's production cost.
To this end, metallargist is except, in addition to being optimized in terms of steel quality, two refrigeration techniques, reasonable rolling, being taked
A technical measures be exactly the crystallizer technology using band chamfering.In the prior art, the knot of side straps chamfering is used
Brilliant device technology is commonplace.Crystallizer technology although with band chamfering can effectively solve strand transverse corner crack stricture of vagina
Problem, but, a large amount of production practices results show: use the continuous casting billet that the chamfer crystallizer technology of above-mentioned parameter is produced,
Due to the widest face of its fillet surface and strand formed chamfer angle less, generally less than 135 °, the strand of this shape with
After the operation of rolling in the edge of Strip can not be completely eliminated directly split or stick up the defects such as skin.
Therefore, some metallargists develop the method that the corner to strand rolls both at home and abroad, to obtain corner
Shape more reasonably continuous casting billet.
Such as Chinese patent CN204747439U discloses " a kind of device carrying out the rolling of continuous casting billet corner ", and this device is put
Put the left and right sides at strand, i.e. every side at strand and have about one two ends chamfering roll with convex edge, drive
Driving under, the chamfering roll with convex edge rolls to strand, and utilizes the convex edge of roll to roll the corner of strand, it is achieved
Chamfering to strand corner, optimizes corner shape further, directly splits to meeting elimination edge in the cut deal broadening operation of rolling
Or stick up the demand of the defects such as skin.But, when production application, the chamfering roll with convex edge is with the side extruded from side
Formula is rolled to strand corner, rather than the corner of strand is rolled by forward.This most inevitably brings two problems: one is
Draught pressure is big, and two is owing to friction makes roll campaign reduce.
Summary of the invention
For defect and deficiency present in above-mentioned prior art, it is an object of the invention to provide one and there is inclination roll
Two roller continuous casting billets roll angle apparatus.
To achieve these goals, the technical scheme is that
The present invention provides a kind of two roller continuous casting billets tilt with roll to roll angle apparatus, and this device includes chamfering roll 1, rolls
Roller support frame 3, connector 4 and driving push rod 5；
Described roll stand frame 3 is connected with the driving push rod 5 that can move 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 becomes inclination angle with strand width face；This device is arranged on
Continuous casting billet 6 left and right sides, rolls the corner of continuous casting billet 6 continuously.
Two chamfering rolls 1 on two cantilever ends of described roll stand frame 3 are symmetrical arranged, or asymmetric set
Put.
Two cantilever ends of described 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 roll shaft 2 of described chamfering roll 1 and the wide face setting at an angle of continuous casting billet 6, α angle is 0 °～45 °；Chamfering roll 1
Wide of roll surface and continuous casting billet 6 or the curved cut line of the arc roll surface of chamfering roll 1 and continuous casting billet 6 wide face contact point and company
The wide face setting at an angle β of strand 6, β angle is 1 °～45 °.
Described chamfering roll 1 is Split type structure with roll shaft 2, or is structure as a whole.
The cylinder that roll surface is uniformity of described chamfering roll 1, or be uneven frustum shape, or be arc
The frustum of shape, or be shape with groove.
A diameter of the 100～350mm of described chamfering roll 1, the roll surface a length of 100～350mm of chamfering roll 1.
Promoting the driving force driving push rod 5 motion is hydraulic coupling, electric power or mechanical force.
This device is arranged on the exit of conticaster, or is arranged on continuous casting machine fan-shaped intrasegmental part.
This device is for the rolling of the corner of square billet, rectangular bloom or slab, and the thickness of strand being suitable for is 90mm～500mm.
This device had both been suitable for the rolling of chamfering continuous casting billet, was also suitable for right angle strand and the rolling of arc chord angle continuous casting billet.
Compared with prior art, the beneficial effects of the present invention is:
Apparatus of the present invention are arranged on the continuous casting billet left and right sides, along with the carrying out of conticaster process of billet withdrawal, have inclination roll
Two roller continuous casting billets roll the push rod 5 that drives of angle apparatus and move towards continuous casting billet under the driving of power, and the corner to continuous casting billet 6
Roll.Then, along with the motion of strand, the continuous corner to continuous casting billet 6 of chamfering roll 1 carries out rolling rolling, and chamfering is rolled
The amount of rolling in continuous casting billet 6 corner is mainly determined by roller 1 by the driving force driving push rod 5, driving force the biggest continuous casting billet corner
Chamfering amount is the biggest.Simultaneously as the axle of chamfering roll 1 is to tilt, the roll surface of chamfering roll 1 is coordinated to tilt, it is possible to obtain
Continuous casting billet corner is carried out the preferable angle of forward rolling, and under conditions of less roll-force, obtains required strand corner
Shape.Simultaneously as the friction decreased between roll and continuous casting billet, roll campaign is greatly improved.
The present invention can realize the rolling of the forward to continuous casting billet corner, and resistance is little, plant maintenance is simple therefore to have rolling
Etc. advantage.
