Description
Technical field
The utility model is related to a kind of hot strip mill edger roll scraper plate, belongs to metallurgical equipment parts technical field.
Background technology
Generally, steel billet will be heated in the heating furnace in containing oxidizing atmosphere before the rolling, the temperature of heating furnace
Degree is more than 1000 °C, and the heat time is typically even longer at 2~3 hours so that billet surface is with the oxygen in stove in high temperature
It is lower to occur vigorous reaction and generate a large amount of oxide skins.
Steel billet is as working face, and its outermost hardness is very high.Strike off, clear up and come off and accumulate from billet surface
Iron oxide scurf, it is to avoid iron oxide scurf is entered in bearing, requires to be arranged on the scraper plate below roller stock during striking off
Oxide skin can be cleaned out with the rotation of roll.However, there is problems with the prior art：First, scraper plate upper plate and
The front end of column is flushed, and the iron oxide scurf under scraping easily is fallen into be blocked into Bearing gaps；Second, fix the logical of scraper plate
Hole site, because its hardness is high, increases the difficulty of drilling, tapping close to the surface part of edger roll.
Utility model content
The utility model technical issues that need to address are how to provide a kind of convenient drilling, the hot strip mill edger roll of tapping
Scraper plate.
In order to solve the above technical problems, the technical scheme that the utility model is used is：
A kind of hot strip mill edger roll scraper plate, edger roll scraper plate includes circular arc bottom plate（1）Be fixed on bottom plate（1）Middle is vertical
Post（2）, column（2）Including a long square column and a long side using long square column as the trapezoidal column of bottom, the upper bottom of trapezoidal column is dashed forward
Go out in bottom plate（1）Outer rim, two long sides of long square column are in bottom plate（1）The inner side of inner edge, bottom plate（1）Two ends it is symmetrical
Two through holes for fixing edger roll scraper plate（3）, through hole（3）With bottom plate（1）The distance of inner edge is less than through hole（3）With bottom plate（1）
The distance of outer rim.
Technical solutions of the utility model further improvement is that：The upper bottom of trapezoidal column protrudes bottom plate（1）The distance of outer rim
It is circular arc bottom plate（1）Arc it is wide 1/3~1/5.
Technical solutions of the utility model further improvement is that：The long back gauge circular arc bottom plate of long square column（1）Inner edge
Distance is circular arc bottom plate（1）Arc it is wide 1/5~1/8.
Technical solutions of the utility model further improvement is that：Bottom plate（1）With being provided with 3 on the edge of body of roll contact surface
To 8 millimeters of chamfering, the angle of chamfering is 45 °.
Technical solutions of the utility model further improvement is that：Through hole（3）Internal diameter be 24~27mm.
Technical solutions of the utility model further improvement is that：Through hole（3）To bottom plate（1）The distance and through hole of inner edge
（3）To bottom plate（1）The ratio of distances constant of outer rim is 2:3~3:4.
Technical solutions of the utility model further improvement is that：Column（2）Thickness is bottom plate（1）The 10~15 of thickness
Times.
Technical solutions of the utility model further improvement is that：The section of trapezoidal column is isosceles trapezoid.
Technical solutions of the utility model further improvement is that：The angle of inclination of two waists of isosceles trapezoid is 30 °~
45°。
By adopting the above-described technical solution, the technological progress that the utility model is obtained is：
The utility model passes through the former scraper plate upper plate of change and the relative position relation of column so that kept with bearing block
In the case of safe distance, reduce install radius, reach scrape, the effect of scale blowing.
The utility model is moved due to the position of through hole to the center of edger roll, is moved into the relatively low edger roll of hardness
Internal layer so that punching is easier for installation, reduces the difficulty of fixed scraper plate.
Added in the utility model on the edge of bottom plate and end surface of roll contact surface to 8 millimeters of chamfering, chamfering it is big
Small is 45 °.The bottom surface contacted with the body of roll compared to bottom plate in the prior art eliminates 20 to 30 ° of chamfering, makes and body of roll end
The contact area in face expands, and improves the mounting stability of scraper plate.
The scraper plate designed in the utility model is made up of bottom plate and column, and column section is shaped as bottom protrusion the bottom of at
The isosceles trapezoid of the outer rim of plate, and can will be struck off due to the streamline shape of two waists, clear up what is come off and accumulate from steel billet
Iron scale, it is to avoid iron oxide scurf is entered in bearing.The scraper plate flushed compared to bottom plate in the prior art and column, with more
Good scraping effect, and it is more efficient.Simultaneously because bottom plate and through hole lean on inner with respect to column, reduce bottom plate and it fixes spiral shell
The abrasion of nail, greatly prolong its service life, it is to avoid edger roll is on active service the later stage because of serious wear（It is in itself and fixed including scraper plate
Screw cap）And occur scraper plate damage, come off, it is caused scrape, cleaning effect reduction, or even it is necessary replacing or install newly scrape
Plate.
