Embodiment
The implementation of specific embodiment has been described below in detail and has used.It will be appreciated, however, that the specific embodiment discussed
It is merely illustrative implementation and uses ad hoc fashion of the present utility model, and unrestricted scope of the present utility model.Retouching
When stating, the statement in locations of structures direction such as upper and lower, left and right, top, bottom of all parts is not absolute, but phase
To.When all parts are arranged as shown in FIG., the statement of these directions is appropriate, but the position of all parts changes in figure
When, the statement of these directions is also corresponding to be changed.
Fig. 1 shows the part inside milling train, is provided with the band of with good grounds one embodiment of the present utility model
Surface degreasing device.With reference to Fig. 1, there are two support rollers 11, about 14 two working rolls 12,13, band up and down inside milling train
15 are rolled between two working rolls 12,13, and are rotated with the high speed of working roll from inlet of rolling mill side (left side in Fig. 1)
It is sent to milling train outlet side (right side in Fig. 1).In Fig. 1, oil guide plate 21 is installed on the top in milling train, it can
Stop most of excess oil from the top drippage in milling train, oil guide groove is respectively provided with the two ends of oil guide plate 21, so that excess oil
It can be collected in the oil guide groove.Because oil guide plate possibly can not stop from whole excess oil under the top drippage in milling train,
Therefore oil drain pan 22 is fixed with the lower section of oil guide plate 21, further to stop and receive the excess oil of drippage.Under oil drain pan 22
Side is fixed with upper backup roll oil scraping plate 23, and the upper backup roll oil scraping plate 23 is fixed on the bearing block in milling train and positioned at upper support
The upper left side of roller 11.Equally, it is also equipped with lower backing roll oil scraping plate 24 in the adjacent place of lower backing roll 14.Upper backup roll oil scraping plate
23 and lower backing roll oil scraping plate 24 can using oil scraping plate of the prior art or scraper form, it can be with upper backup roll 11
Used cooperatively with lower backing roll 14, the excess oil on body surface is struck off during two support rollers up and down rotate at a high speed.This
Gap between two support roller oil scraping plates and upper backup roll 11 and lower backing roll 14 can according to various sizes of support roller come
Regulation, so as to suitable for different types of milling train.Upper backup roll oil scraping plate 23 and lower backing roll oil scraping plate 24 can bases
Need and be arranged at the other positions of neighbouring upper backup roll 11 and lower backing roll 14, however it is not limited to the position shown in Fig. 1.
As can see in Fig. 1, two arcs gear oil clots 25 are each provided with the roll neck of upper backup roll 11, they can be resisted against
On the surface of roll neck.Gear oil clot 25 can stop that the cooling and lubricating of inlet of rolling mill side is trickled through and be worn at the roll neck of support roller both sides
Cross the oil of support roller, at the same be also capable of barrier support roller roll neck itself at a high speed rotate during will be attached to thereon oil from
Entrance side takes outlet side to and then is splashed on band upper surface.The quantity of gear oil clot can be set as needed, and not
It is only limitted to the quantity shown in Fig. 1.Oil guide plate 21, oil drain pan 22, upper backup roll oil scraping plate 23, lower backing roll oil scraping plate 24 with
And gear oil clot 25 can be made by different nonmetallic wear-resistant materials.
With continued reference to Fig. 1, provided with the oily plate 26 of gear at the outlet side of milling train, it by Driven by Hydraulic Cylinder and can pass through liquid
Cylinder pressure is coupled in inside milling train.The oily plate 26 of gear can weld to be formed by carbon steel.Along the length direction point of the oily plate 26 of gear
Fixed (for example, by welding) does not have first jet 27 and second nozzle 28 on the oily plate 26 of gear.First jet 27 and second
Nozzle 28 can have two flat nozzles of big flow being symmetrically arranged on the width of band respectively, and nozzle can be closed by aluminium
Metalworking is formed, and it can be single mouth nozzle or double mouth nozzles, or any other species of the prior art nozzle.Nozzle
In can provided with air-flow be oriented to demixing plate, to be oriented to the gas that nozzle is ejected, so as to prevent air turbulence.First
Nozzle 27 is towards the roll gap injection between upper backup roll 11 and top working roll 12, to purge the excess oil in roll gap, second nozzle 28
Eject slot towards between the upper surface of top working roll 12 and band 15, to purge the excess oil in gap.
Fig. 2 (a) and Fig. 2 (b) respectively illustrate the injection schematic diagram of this two groups of nozzles, wherein, horizontal dotted line represents nozzle
The surface of injection, vertical dotted line represents the longitudinal axis on the length direction of the oily plate 26 of gear, and oblique dotted line represents first jet
27 and the gas injection direction of second nozzle 28.As seen in Fig. 2 (a) and Fig. 2 (b), first jet 27 has one group of spray
Mouth 271 and 272, second nozzle 28 has one group of nozzle 281 and 282, and nozzle 271 and 272 sprays gas with the direction inwardly intersected
Body, to cause the oil dispersed accumulated in the middle part of roll gap between upper backup roll 11 and top working roll 12, and nozzle 281 and 282 with
The direction gas injection outwards dissipated, so that the excess oil in gap between purging the upper surface of top working roll 12 and band 15.
The angle of injection is adjustable, and it can be determined according to the width of different roll surface length, strip surface, also, be passed through
The oily plate 26 of Driven by Hydraulic Cylinder gear, first jet 27 and second nozzle 28 can be moved with the oily plate 26 of gear in milling train, from
And the direction and position of gas injection can be changed.By this arrangement, the roll gap between upper backup roll 11 and top working roll 12
In excess oil and top working roll 12 and band 15 upper surface between gap in excess oil can be purged off, and will not
Cause air turbulence.The gas that first jet 27 and second nozzle 28 spray is by plant compressed air central gas supply, and by proprietary
Gas control cabinet is controlled distribution.
It also show in Fig. 1 and oil-containing groove 29 be provided between first jet 27 and second nozzle 28, to receive from milling train
The excess oil of exit drippage, can be processed by ordinary carbon steel and form oil-containing groove and oil-containing groove is heat-treated.In second nozzle
28 top is also provided with metallic plate 30, and metallic plate 30 is processed to protect second nozzle 28, metallic plate 30 by brass sheet
On be additionally provided with left and right oil guide groove, the oil got off with receiving top working roll 12 to be splashed in rotary course, so as to further stop remaining
Oil is dropped on the upper surface of band 15.
According to principle of the present utility model, minimum and maximum strip width and milling train that operating personnel can be according to production
Situation adjusts the size of the device for removing oil on surface, can also select strip surface oil removing according to actual strip width
The size of device.In addition, operating personnel can be according to actual use situation come by each function part in device for removing oil on surface
Part carries out different combinations, replacement, deletes or increase.Device for removing oil on surface of the present utility model can be applied not only to not
With the rolled strip of breadth width, and it can use (especially in fast mill) in the milling train of various speed smaller
Air consumption effectively to strip surface carry out oil removing.
Technology contents of the present utility model and technical characterstic are had revealed that above, it being understood, however, that of the present utility model
Under creative ideas, those skilled in the art can make various changes and improve to design disclosed above, but belong to this reality
With new protection domain.The description of above-mentioned embodiment is exemplary rather than restricted, protection of the present utility model
Scope is determined by claim.
