Abstract
The invention discloses a double-layer slag scraping structure of a lower working roller slag scraping plate. The double-layer slag scraping structure comprises the slag scraping plate. The two ends of the slag scraping plate and a machine frame of a lower working roller are fixed through bolts. The double-layer slag scraping structure is characterized in that a bakelite strip is arranged at an L-shaped groove opening at the front end of the slag scraping plate and is fixed through a bolt, a bakelite plate is arranged at the top face of the slag scraping plate and is fixed through a bolt, and the double-layer slag scraping structure is formed. According to the double-layer slag scraping structure, an existing steel strip pressing rubber strip structure is changed, bakelite strip and bakelite plate materials are used, fixing is carried out through the bolts, the structure is stable, impact resistance is achieved, the service life is long, maintaining workload is lowered, and the rolling mill operating rate is improved. Two slag scraping structures are arranged on the slag scraping plate, the problem that during a steel plate rolling process, scale scrap iron scatters on a rolled piece is effectively avoided, and slag scraping effect is good.
Description
Technical field
The present invention relates to four-high mill equipment, the bilayer that relates in particular to a kind of bottom working roll scum board is scraped slag structure.
Background technology
Existing four-high mill is for rolling medium plate, and its structure is made up of two working rolls of upper lower support roll and setting therebetween.In order to prevent in the operation of rolling that iron scale iron filings are scattered on rolled piece and affect plate surface quality, before and after bottom working roll, be provided with in pairs scum board, be provided with a thick 20mm, wide 55mm, long L(roll surface length at the front end edge length direction of scum board) rubber strip, push down with steel bar thereon, be used for scraping slag.When scum board is installed, rubber strip is close to body surface, prevents that iron scale iron filings from entering in rolling interval.This fixed structure is in the working roll operation of rolling under huge impact force action, can make hold-down bolt on steel bar loosening, thereby often because rubber strip is deviate from or displacement causes and strikes off the disabler of iron scale iron filings, must process, affect operating rate of rolling mill, increased maintenance load.
Summary of the invention
The object of this invention is to provide a kind of Stability Analysis of Structures, shock resistance, scrapes slag effective, and the bilayer of a kind of bottom working roll scum board of long service life is scraped slag structure.
The object of the present invention is achieved like this: a kind of bilayer of bottom working roll scum board is scraped slag structure, comprise scum board, scum board two ends are fixed by the frame of bolt and bottom working roll, it is characterized in that, front end " L " shape notch at scum board arranges bakelite bar, fixes with bolt; At scum board end face, bakelite plate is set, fixes with bolt, form bilayer and scrape slag structure.
In the middle of described bakelite bar, be equidistantly provided with along its length through hole, corresponding with the bolt arranging on " L " shape notch.
In the middle of described bakelite plate, be equidistantly provided with along its length strip through hole, corresponding with the bolt that scum board end face arranges.
Mounted in pairs of the present invention is at bottom working roll front and back position.Further illustrate as an example of a side example.First the through hole on bakelite bar is enclosed within on the bolt of equidistant setting on scum board " L " shape notch, fix with nut, again the strip through hole on bakelite plate is enclosed within on the bolt of scum board end face setting, screw on nut, adjust scum board and bakelite plate position, make bakelite bar, bakelite plate working edge on scum board be close to body surface, by the bolt on the hangers of scum board two ends and the nut screwing clamping on bakelite plate, can use.
Compared with prior art, its advantage is in the present invention: change existing steel bar and compress rubber strip structure, adopt bakelite bar, bakelite plate material, and fix with bolt, and Stability Analysis of Structures, shock resistance, long service life, has reduced maintenance load, has improved operating rate of rolling mill.And twice are set on scum board and scrape slag structure, effectively prevented in steel plate rolling process that iron scale iron filings are scattered on rolled piece and cause the defects such as plate surface quality pit, pit, scrape slag effective.
Brief description of the drawings
Fig. 1 is top view of the present invention.
Fig. 2 is that the present invention coordinates installation side view with bottom working roll.
In figure: 1, scum board, 2, bakelite plate, 3, bakelite bar, 4, bolt, 5, bottom working roll, 6, hangers, 7, strip through hole.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.Referring to Fig. 1, Fig. 2, a kind of bilayer of bottom working roll scum board is scraped slag structure, comprises scum board 1, scum board 1 two ends are fixed by bolt 4 and the frame of bottom working roll 5, it is characterized in that, at front end " L " the shape notch of scum board 1, bakelite bar 3 is set, fixing with bolt 4; At scum board 1 end face, bakelite plate 2 is set, fixing with bolt 4, form bilayer and scrape slag structure.In the middle of described bakelite bar 3, be equidistantly provided with along its length through hole, corresponding with the bolt 4 arranging on " L " shape notch.In the middle of described bakelite plate 2, be equidistantly provided with along its length strip through hole 7, corresponding with the bolt 4 that scum board 1 end face arranges.
embodiment:as shown in Figure 1, scum board 1 front end " L " shape notch (referring to Fig. 2) is provided with bakelite bar 3, in the middle of bakelite bar 3, be equidistantly provided with along its length an exhausting hole, corresponding with the row's bolt 4 arranging on " L " shape notch, be convenient to install, on bakelite bar 3, the setting of through hole number is as the criterion to install firmly; In the middle of bakelite plate 2, be also equidistantly provided with along its length platoon leader's strip through-hole 7, the object that strip through hole 7 arranges is that bakelite plate 2 is convenient to regulate to bottom working roll 5 roll surfaces after gap during steel plate rolling is large, the present embodiment is designed to kidney-shaped through hole, the row's bolt 4 arranging with scum board 1 end face is corresponding, and on bakelite plate 2, the setting of strip through hole 7 numbers is also as the criterion to install firmly.Taking 3800mm four-high mill as example: working roll roll surface length 3800mm, for fixing of bakelite plate 2, the strip through hole 7 of 12 width 18mm is set with 30mm spacing on bakelite plate 2, fixing with Ф 16mm bolt 4, can meet fixing requirement; For fixing of bakelite bar 3, the manhole of 10 Ф 12mm is set with 34mm spacing on bakelite bar 3, fixing with Ф 12mm bolt 4, can meet fixing requirement.Through hole on bakelite plate 2, bakelite bar 3 is enclosed within on corresponding bolt 4, fixes with nut.Referring to Fig. 2, two scum boards 1 are hung in to bottom working roll 5 front and back positions, adjust scum board 1 and bakelite plate 2 positions, make bakelite bar 3, bakelite plate 2 working edges on scum board 1 be close to body surface, nut 4 on bolt on two ends hangers 64 and bakelite plate 2 is tightened, can be used.
