Abstract
The utility model provides an apparatus for eliminating edge residue of flattening liquid on a cold rolled steel strip, which is composed of air knives and air nozzles. The utility model is characterized in that the utility model is composed of two groups of air knives which are respectively arranged at side drawing devices at two sides of an outlet of a machine frame, and the air nozzles are arranged on the air knives. As a flatten line of the utility model is additionally provided with a blow off device for edge residual liquid, under the condition that the flattening liquid of the middle part can be thoroughly blown off, the utility model ensures that the edge residual liquid can be cleaned cleanly, and the flattening tarnish caused by the edge residue of the flattening liquid can be eliminated, the defect number of flattening machine sets can be reduced, thereby, the surface quality of a steel strip can be ensured.
Description
Technical field
The utility model belongs to the cold-rolled steel sheet technology field, relate to a kind of remove cold rolling strap steel plate surfacing liquid residual device, specifically be a kind of residual device of the smooth liquid of cold-strip steel limit portion of removing.
Technical background
In recent years in order to improve cold-strip steel antirust ability and improve strip surface quality, extensively adopt water-soluble or the oil-soluble antirust agent is made smooth liquid and sprayed roll gap, it is smooth to carry out wet method.Temper rolling technology has a lot of advantages, but also has defectives such as smooth liquid is residual, wherein especially is difficult to control so that smooth liquid limit portion is residual.Common smooth liquid purging system all is an entire arrangement, do not consider the influence of wide variety, simultaneously the steel plate width scope is purged with an air draft mouth, the band steel is in wet smooth process, and the frame smooth nozzle for liquid of upper and lower twice that enters the mouth is ejected on the surface of steel plate, and a large amount of smooth liquid are along with steel plate travels forward at a high speed, the smooth liquid at middle part is through roll the time, after being rolled by roll, the blowing through outlet afterwards purges, with the smooth liquid at middle part can be whole blow off.But the smooth liquid of limit portion, because steel plate has certain thickness, there is roll gap between the upper and lower working roll, cause the smooth liquid of limit portion not rolled by roll, cause the residual of the smooth liquid of limit portion, and owing to the angle reason that the blowing of outlet twice purges, it is very low to reach air quantity arrival steel plate limit portion, can not guarantee that the smooth liquid of limit portion all purges clean.Therefore, the residual ubiquitous problem of smooth operation that becomes of belt steel flating liquid limit portion.
Summary of the invention
At the residual ubiquitous problem of smooth operation that becomes of above-mentioned belt steel flating liquid limit portion, the invention provides a kind of residual device of smooth liquid limit portion of eliminating, the limit portion that can effectively eliminate smooth liquid is residual.
The purpose of this utility model is achieved in that it is made up of air knife, tuyere, is characterized in being made up of 2 groups of air knives, and air knife is installed in respectively on the both sides layback device of frame outlet, and tuyere is installed on the air knife.
Concrete structure of the present utility model has, and every group of air knife is made of upper and lower air knife, and upper and lower air knife is respectively installed 2 tuyeres, and air knife becomes certain included angle with steel plate, and its angle is 40 °～50 °, and best angle is 45 °.
Concrete structure of the present utility model also has, and the layback device is fixed on the planisher delivery guide, and the layback device has slideway, slide block and pull bar, and pull bar connects slide block, and slide block is installed in the slideway, and air knife is connected with slide block.
The utility model is owing to set up the blow device of the residual liquid of limit portion on flat line, under the situation that the smooth liquid at middle part can all blow off, guaranteed that the residual liquid of limit portion also can clean totally, eliminated the smooth corrosion that causes because smooth liquid limit portion is residual, reduce smooth unit defects count, thereby guaranteed the quality of surface of steel plate.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the layback schematic representation of apparatus.
The specific embodiment
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is elaborated.
As shown in Figure 1, the utility model is made up of air knife 1, tuyere 2, is characterized in being made up of 2 groups of air knives 1, and air knife 1 is installed in the both sides of frame 3 outlets respectively, and tuyere 2 is installed on the air knife 1, and tuyere 2 purges the steel plate of steel plate fore side and transmission side respectively.
Concrete structure of the present utility model has, every group of air knife is made of upper and lower air knife, upper and lower air knife is respectively installed 2 tuyeres 2, purge upper and lower belt steel surface respectively, wherein tuyere 2 requires identical with tuyere in the frame, totally 12 holes, and type distributes in the shape of a spiral, in the use, because blowing pipeline and steel plate limit portion at a distance of 6～10cm, consider the length of air knife, the air knife that requires to guarantee side-blown becomes certain included angle with steel plate, its angle is 40 °～50 °, and best angle is 45 °, and it is residual to satisfy the smooth liquid that residues in portion 0-100mm place, steel plate limit.
As shown in Figure 2, the layback device is fixed on the planisher delivery guide, the layback device has slideway 6, slide block 5 and pull bar 4, and pull bar 4 connects slide block 5, and slide block 5 is installed in the slideway 6, air knife 1 is connected with slide block 5, in the process of using, can be according to the difference of steel plate width, the pull bar 4 that blows is surveyed in pulling, slide block 5 is fixed on satisfies the position of 6～10cm apart, guarantee good blowing effect perpendicular to the blowing pipeline of band steel and steel plate limit portion.
