A kind of edger roll of energy cancellation band steel surface point line defect, comprise edger roll body, edger roll body has two, symmetrical and the setting of equal altitudes formula, edger roll body is provided with intermediate throughholes from top to down, edger roll power transmission shaft is inserted this edger roll body by intermediate throughholes and through, and the edger roll bedframe be connected with edger roll power transmission shaft is provided with at edger roll body lower part, the body of roll of the side of edger roll body offers the working surface of vertical roll in inverted trapezoidal, between the working surface of vertical roll being then placed in two edger rolls with steel, and contact with working surface of vertical roll, be rolled operation.The utility model can not be expressed to edger roll upper surface and the lower surface of working surface of vertical roll, so each operative end surface of edger roll produces defect seldom, even and if end face has bonding defect also again can not pass to belt steel surface, the some line defect on elimination steel edge portion surface.The utility model is applicable to the field of various roughing operation standing roller frame for preventing belt steel surface from producing some line defect.
Description
Technical field
The utility model relates to a kind of roll, particularly relates to a kind of edger roll of the roughing operation standing roller frame energy cancellation band steel surface point line defect be applied in the automation field of steel production industry.
Background technology
At present, a kind of roughing mills has often been used in some large-scale steel production enterprise, this roughing mills is made up of the standing roller frame of four band edger rolls usually, called after E1/R1, E2/R2, E3/R3 and E4/R4 standing roller frame respectively, wherein E1 standing roller frame is two roller horizontal mills of band pass, and all the other E2 ~ E4 standing roller frames are edger roll plain-barreled roll four-high mills not with pass, wherein:
The pressure measurement of 1.E1 edger roll a time is maximum can side pressure 120mm, the effective lateral pressure amount 150mm of three passage pressure measurement, maximum lateral pressure 800 tons, roll-force according to 2750KNm, one-sided side pressure speed 80mm/S;
The maximum lateral pressure of 2.E2 edger roll 380 tons, roll-force according to 560KNm, one-sided side pressure speed 80mm/S;
The maximum measuring pressure of 3.E3 and E4 edger roll 180 tons, roll-force according to 150KNm, one-sided side pressure speed 80mm/S.
In these standing roller frames, E1 edger roll lateral pressure amount accounts for about 60% of total lateral pressure amount of four frames, and E2 edger roll five passes lateral pressure amount account for about 20%, E3 and E4 edger roll lateral pressure amount about 20%.E1 ~ E4 edger roll opening degree is 600 ~ 2050mm.E1 edger roll size diameter: 1050 ~ 1100mm, highly: 650mm; E2 edger roll size diameter: 1000 ~ 950mm, highly: 455mm; E3 and E4 edger roll size diameter: 880 ~ 830mm, highly: 455mm.And produce line rolled slab raw thickness 220 ~ 250mm, wherein 90% sotck thinkness is 250mm.
These vertical millers above-mentioned in process of production; field worker finds; the band steel produced often there will be steel edge portion both sides point wire shape defect; along with product quality requires more and more higher, this edge point line defect can not be met consumers' demand, therefore; steel edge portion in enormous quantities some line defect is often had to be blocked in production; particularly when the middle and later periods in E1 edger roll service life, this phenomenon is especially serious, a large amount of band steel degradation of blocking or sentence useless, loses huge.
And block to reduce product because of edge point line defect the loss caused; steel rolling field worker and administrative staff take a lot of way; can not overturn the present conditions always; the probability that finally can only produce according to this defect and E1 edger roll life-span service time; E1 edger roll life cycle was shortened to 4 weeks from original 6 weeks; situation just takes a turn for the better to some extent; but or existing product quality requirement can not be met; the most in short-term E1 edger roll life cycle is dropped to 2 weeks and change once, which increase many nonscheduled down times and cost of labor.
Pass through trace analysis, discovery causes steel edge portion point wire defect cause, be E1 edger roll be hole type design, its objective is and guarantee steel edge portion organizational requirements, but because the design of E1 vertical roll hole is unreasonable, blank in the operation of rolling is caused to extrude by side pressure, both sides can produce bone-shaped projection, bossing band steel directly contacts with bottom surface with the end face of vertical roll hole too greatly because extruding, repeatedly extruding contact can at E1 vertical roll hole end face, side and bottom surface produce sticky iron dross, dross extrusion billet surface has impression to pull to body, point line defect is produced finally by horizontal roller rolling, analyze from E1 vertical roll hole size design, roller pass height 250mm under prior art, end face and bottom surface band constant slope, and the sotck thinkness of rolling inherently 250mm, adding side pressure effect worsens very fast to pass working face, the sticky iron dross produced is large to a certain extent, damage can be caused to blank, and the dross of edger roll above water-cooled is also very hard, some dross is very sharp-pointed, fatal especially to scuffing body blank, point line defect Producing reason is exactly like this.
Scrap old roller aperture type measure by using from new roller E1 edger roll, machine maintenance mill under general each E1 edger roll, pass size can increase a little, but the maximum variable quantity of pass is about 270mm when scrapping to edger roll, so new roller has just gone up machine due to the also no formation of sticky iron dross, edge point line defect is just few, on old edger roll machine because of pass size large, edge point line defect can gently a bit, steel edge portion point line defect is analyzed according to tracking results, produce on E1 Edger Roll working face completely, therefore, want thoroughly to eliminate this mass defect, the breach of dealing with problems will be found from E1 vertical roll hole.
Utility model content
The band steel caused due to its structural reason in order to the edger roll solved under prior art directly contacts with bottom surface with the end face of vertical roll hole too greatly because extruding, repeatedly extruding contact can at E1 vertical roll hole end face, side and bottom surface produce sticky iron dross, dross extrusion billet surface has impression to pull to body, the problem of some line defect is produced finally by horizontal roller rolling, the edger roll structure of the utility model by redesigning, do not change edger roll body construction, edger roll service life is not affected yet, and in the immovable situation of product line, provide a kind of edger roll of energy cancellation band steel surface point line defect, this edger roll can prevent extruding edger roll top end face, the defect that each operative end surface of edger roll is produced reduces, even if end face has bonding defect also again can not pass to belt steel surface.Concrete structure of the present utility model is as described below:
An edger roll for energy cancellation band steel surface point line defect, comprises edger roll body, it is characterized in that:
Described edger roll body has two, the symmetrical and setting of equal altitudes formula;
