Abstract
The utility model relates to an emulsion scrapper device for a support roll of a cold mill, which belongs to a cold mill auxiliary apparatus. The utility model is characterized in that the back upper part of the support roll (8) of an end rack mill is provided with two scraper slide carriages (3); the scraper slide carriages are fixed above the inside of bearing blocks of the upper support roll by screw bolts (4); a slide plate (1) is arranged between the scraper slide carriages; two adjusting screw bolts (2) are arranged between the slide carriages and the slide plates. A felt (7) is fixed to the lower part of the slide plate (1) by a press plate (5) through the screw bolts (6), and a contact point of the felt (7) and the surface of the support roll forms a beta angle with a horizontal line above the inlet side. The installing direction of the scraper forms an alpha angle with a vertical line. When the utility model is used, not only is the effect of scraping emulsion of the support roll favorable but the quality of finished strip is enhanced as well.
Description
A kind of cold-rolling mill backing roll emulsion screeding device belongs to the cold-rolling mill auxiliary equipment, is particularly useful for removing the emulsion on the milling train backing roll.
Existing cold rolling unit, especially used equipment, there is not the emulsion scavenge unit on the backing roll of a lot of milling trains, for example the Anshan iron and steel plant cold rolling mill is from the four-roller type four frame cold continuous rollings of West Germany's introduction, after technological transformation, its installation level increases, but emulsion is taken on the finished strip surface when the backing roll rotation of finished frame, have a strong impact on the Technology for Heating Processing of finished strip, and produce the black-tape defective at belt steel surface.
The purpose of this utility model provides a kind ofly can remove milling train backing roll emulsion, reduce the finished product belt steel surface produces the black-tape phenomenon, improves the cold-rolling mill backing roll emulsion screeding device of the quality of finished strip.
The utility model is to realize like this, it is by the scraper plate slide, slide plate, felt and bolt are formed, its main points are the back upper places at last rolling mill backing roll (8), two scraper plate slides (3) are installed, and use bolt (4) to be fixed on the inside front of two bearing blocks of top backing up roll respectively, the centre is provided with slide plate (1), between slide (3) and slide plate (1), be provided with two respectively and adjust bolt (2), felt (7) is fixed in the slide plate below with pressing plate (5) by bolt (6), and felt (7) becomes β angle with horizontal line with supporting roll surface contact point above entrance side, the scraper plate installation direction becomes the α angle with vertical line.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a Facad structure schematic diagram of the present utility model.
Fig. 2 is the A-A cutaway view of the utility model Fig. 1.
Fig. 3 is the schematic diagram that the utility model is installed in last frame backing roll back upper place milling train.
With reference to Fig. 1, Fig. 2, the utility model is in the back upper place of original four frames end rolling mill backing rolls (8) two scraper plate slides (3) to be installed, and use bolt (4) to be fixed on the inside front of two bearing blocks of bolster respectively, the centre is provided with slide plate (1), two slide plates are set respectively between scraper plate slide (3) and slide plate (1) adjust bolt (2), adjustment bolt (2) can drive slide plate (1) and slide up and down, in slide plate (1) below felt (7) is installed, felt (7) is fixed in the below of slide plate (1) by pressing plate (5) with several bolts (6).The effect that two slide plates are adjusted bolts (2) is for when the backing roll vary in diameter, adjusts felt and keeps excellent contact with the top backing up roll body surface, and its exposure level must be proper, otherwise it is bad to press De Taisong to scrape the emulsion effect, press felt serious wear too tightly.With reference to Fig. 3, another characteristics of the present utility model are that felt becomes β angle with horizontal line with the body surface contact point above entrance side, and its best angle β=40 ° facts have proved, this position is body of roll emulsion the easiest minimum wiping off a little.Be zero when felt had just contacted with body surface when this device was installed, the scraper plate that will have felt (7) is then adjusted the x distance downwards, its optimum degree of adjusting felt and body of roll distance is x=5mm, the scraper plate installation direction becomes ° angle, α=30～35 with vertical line, this direction helps emulsion scraping on the backing roll.
Another characteristics of the present utility model are that the width of felt (7) must be greater than the width of top backing up roll body surface, like this can be emulsion scraping on the whole body of roll width.
This device is owing to adopted the adjustment bolt to adjust the height of backing roll and scraper plate felt (7), guaranteed that felt contacts with the good of body surface, the wearing and tearing of felt have been reduced, screeding device is not subjected to the influence of roll lifting during work, must often not adjust, need only be when changing backing roll, once adjust according to the roller diameter size, and it is effective to strike off the backing roll emulsion, has improved the quality of finished strip greatly, is specially adapted to remove the emulsion on the cold-rolling mill backing roll.
Claims (4)
1, a kind of cold-rolling mill backing roll emulsion screeding device, by the scraper plate slide, slide plate, felt and bolt are formed, it is characterized in that back upper place at last rolling mill backing roll (8), two scraper plate slides (3) are installed, and be fixed on the inside front of two bearing blocks of top backing up roll with bolt (4), the centre is provided with slide plate (1), between slide (3) and slide plate (1), be provided with two respectively and adjust bolt (2), felt (7) is fixed in the below of slide plate (1) by bolt (6) with pressing plate (5), and felt (7) becomes β angle with horizontal line with supporting roll surface contact point above entrance side, the scraper plate installation direction becomes the α angle with vertical line.
2, cold-rolling mill backing roll emulsion screeding device according to claim 1 is characterized in that β=40 that described felt (7) and supporting roll surface contact point form with horizontal line ° above entrance side.
3, cold-rolling mill backing roll emulsion screeding device according to claim 1 is characterized in that α=30～35 that scraper plate installation direction and vertical line form °.
4, cold-rolling mill backing roll emulsion screeding device according to claim 1 is characterized in that the width of described felt (7) must be greater than the width of top backing up roll body surface.
