Abstract
The utility model provides a be used for cold rolled deoiling device of steel band, includes except that oiling roller (1), air knife (2) and scraper blade (3), remove oiling roller (1) total two, the symmetric distribution of mirror image is on the upper and lower both sides of steel band (6), and sets up before the export of rolling mill (5) its characterized in that: be provided with except that the export of the right of oiling roller (1) and rolling mill (5) a set of air knife (2). The utility model discloses a setting gradually behind the roll and disposing the emulsion on cold rolling steel band (6) except that oiling roller (1), air knife (2) and scraper blade (3), not only the effectual face cleanliness that has improved cold rolling steel band (6) has still reduced the off tracking of cold rolling steel band (6).
Description
Technical field
The utility model relates to the cold-rolling process of steel band, especially a kind of degreasing unit for cold rolling band steel.
Background technology
Generally adopt emulsion to carry out lubrication and cooling milling train when steel band carries out cold rolling, by the emulsion that as far as possible must eliminate steel strip surface before curling for the steel band rolled to reduce cold-rolled strip zinc-plated before cleaning difficulty, traditional deoiling method after steel band goes out roll, first removes oiling roller with one group remove most emulsion, and then clean remaining emulsion with water by one group of brush roll, this way has following problem: when 1, brush roll cleans emulsion with water self also emulsified liquid pollute, just clean with water unclean after longevity of service; 2, bring very large frictional force to steel band when brush roll cleans steel band with water, cause the easy sideslip of steel band, scratch, broken belt.
Summary of the invention
For above deficiency, the purpose of this utility model is to provide a kind of degreasing unit for cold rolling band steel, is successively by effectively disposing the emulsion of steel strip surface except devices such as oiling roller, air knife and scraper plates after roll taken out of by cold-rolled steel.
The technical solution of the utility model is achieved in the following ways: a kind of degreasing unit for cold rolling band steel, include except oiling roller, air knife and scraper plate, the described oiling roller that removes has two, the both sides being up and down symmetrically distributed in steel band of mirror image, and before being arranged on the outlet of milling train; Described air knife is arranged on outside the outlet of milling train, and described scraper plate is arranged on the right of air knife, is close to below steel band.
Described air knife has two, the both sides being up and down symmetrically distributed in steel band of mirror image, and from the distance controlling of steel band between 1cm-3cm, the Stress control of air knife is between 1000Pa-3000Pa.
The length of described scraper plate is greater than the width than steel band, is close to below steel band, for scraping the impurity sticking to steel strip surface.
The described bottom except oiling roller, air knife and scraper plate is also provided with accumulator tank, for reclaiming emulsion.
The utility model, by setting gradually the emulsion disposed except oiling roller, air knife and scraper plate on cold-rolled strip after roll, not only effectively raises the pan cleanliness of cold-rolled strip, also reduces the sideslip of cold-rolled strip.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that 2 is air knives, and 3 is scraper plates, and 4 is accumulator tanks, and 5 is milling trains, and 6 is steel bands, and 7 is crimping devices except oiling roller.
Detailed description of the invention
Known by Fig. 1, a kind of degreasing unit for cold rolling band steel, include except oiling roller 1, air knife 2 and scraper plate 3, the described oiling roller 1 that removes has two, the both sides being up and down symmetrically distributed in steel band 6 of mirror image, and before being arranged on the outlet of milling train 5; Described air knife 2 is arranged on outside the outlet of milling train 5; Described scraper plate 3 is arranged on the right of air knife 2, is close to below steel band 6.
Described air knife 2 has two, the both sides being up and down symmetrically distributed in steel band 6 of mirror image, and from the distance controlling of steel band 6 between 1cm-3cm, the Stress control of air knife 2 is between 1000Pa-3000Pa.
The length of described scraper plate 3 is greater than the width than steel band 6, is close to below steel band 6, for scraping the impurity sticking to steel band 6 surface.
The described bottom except oiling roller 1, air knife 2 and scraper plate 3 is also provided with accumulator tank 4, for reclaiming emulsion.
During work, steel band 6 from roll out, first through removing oiling roller 1, described two except the clearance control between oiling roller 1 is between the 0.5mm-1.5mm being greater than steel band 6 thickness, make dispose most emulsion except oiling roller 1, when the poor then increasing of template of steel band 6 is except the gap between oiling roller 1, otherwise, then reduce; Steel band is first through air knife 2 after the outlet out of milling train 5, and the pressure-air that air knife 2 blows out effectively can get rid of remaining emulsion, then strengthens the pressure of air knife when the time that pan cleanliness is low, otherwise, then reduce air pressure to save energy consumption; Steel band 6 after the purging of air knife 2 enters into scraper 3, and scraper 3 is close to below steel band 6, effectively scrapes the impurity sticked to below steel band 6, and then clean steel band 6 enters crimping device 7 and is rolled into coil of strip and is delivered to galvanization production line.
Claims (4)
1. the degreasing unit for cold rolling band steel, include except oiling roller (1), air knife (2) and scraper plate (3), the described oiling roller (1) that removes has two, the both sides being up and down symmetrically distributed in steel band (6) of mirror image, and before being arranged on the outlet of milling train (5), it is characterized in that: be describedly outside equipped with one group of air knife (2) except the right of oiling roller (1) and the outlet of milling train (5).
2. a kind of degreasing unit for cold rolling band steel according to claim 1, be further characterized in that: described air knife (2) has two, the both sides being up and down symmetrically distributed in steel band (6) of mirror image, from the distance controlling of steel band (6) between 1cm-3cm, Stress control during air knife (2) work is between 1000Pa-3000Pa.
