Abstract
The utility model relates to a novel rough rolling edger roll, edger roll shape middle section is the convex of indent, is the inclined plane between the upper and lower plane of middle section both sides and edger roll, and rolling slab is located the roll table between the convex interlude of coexistence roller indent. Compared with the prior art, the beneficial effects of the utility model are that: the corner of the plate blank can be rolled to eliminate corner cracks, so that the edge warping defect of the final finished product of the strip steel is reduced, the plate blank is abutted against a roller way, the torsion instability phenomenon at the tail of the plate blank is prevented, and the product precision is improved.
Description
Technical field
The utility model relates to roughing edger roll roll design in the steel rolling process.
Background technology
Slab is when roughing is rolling, and edger roll is a plain-barreled roll, and the slab bight is the two-dimentional state of cooling; Cooling velocity is fast, temperature is low, bad plasticity, is prone to form chink, forms and sticks up the skin defective; Slab is when the process edger roll is rolling; The slab afterbody is prone to the unstable phenomenon that twists, and finally causes the product afterbody ultra wide, influences product quality.
Therefore, hot rolling production needs a kind of device that can improve slab bight quality and prevent slab afterbody torsional buckling phenomenon, to improve the product precision.
Summary of the invention
The purpose of the utility model provides a kind of novel roughing edger roll, and this device can effectively improve slab bight quality and prevent slab afterbody torsional buckling phenomenon.
For realizing above-mentioned purpose, the utility model adopts following technical scheme to realize:
A kind of novel roughing edger roll, said edger roll roll forming stage casing is the circular arc of indent, is the inclined plane between the lower plane on both sides, stage casing and the edger roll, rolled slab is on the roller-way between the two edger roll indent circular arc interludes.
Compared with prior art; The beneficial effect of the utility model is: can carry out backing to the bight of slab; The elimination corner crack takes place, and sticks up the generation of skin defective to alleviate final finished strip edge portion, and slab is abutted against on the roller-way; Prevent the slab afterbody unstable phenomenon that twists, to improve the product precision.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-edger roll 2-slab 3-roller-way
The specific embodiment
See Fig. 1, a kind of novel roughing edger roll, said edger roll 1 roll forming stage casing is the circular arc of indent, is the inclined plane between the lower plane on both sides, stage casing and the edger roll 1, rolled slab 2 is on the roller-way 3 between the two edger roll indent circular arc interludes.
In the operation of rolling, edger roll 1 rotates, and can carry out backing to the bight of slab 2; Effectively eliminate slab 2 corner cracks, reduce product limit portion and stick up the skin defective, simultaneously; Can produce a downward component to slab 2; Slab is abutted against on the roller-way 3, prevent the slab afterbody unstable phenomenon that twists, finally improve the product precision.
Claims (1)
1. a novel roughing edger roll is characterized in that, said edger roll roll forming stage casing is the circular arc of indent, is the inclined plane between the lower plane on both sides, stage casing and the edger roll, and rolled slab is on the roller-way between the two edger roll indent circular arc interludes.
